Gas exchange and lactate threshold are valid indicators of moderate-intensity aerobic exercise, rat study finds
Researchers at University of Tsukuba identified a previously unconfirmed gas exchange threshold in rats and demonstrated that this threshold, together with the lactate threshold, serves as an indicator of moderate-intensity exercise to determine the effectiveness of training in enhancing aerobic performance.
The study is published in Medicine & Science in Sports & Exercise. This achievement is fundamental for basic research on exercise. It will be useful for researchers in the field of health and fitness promotion as it provides a useful moderate-intensity index for rats.
During incremental aerobic exercise, there are thresholds where blood lactate levels begin to rise, and CO2 production increases rapidly relative to O2 uptake. The former threshold is termed the lactate threshold (LT), and the latter, the gas exchange threshold (GET). In humans, these thresholds are moderate-intensity exercise indices, with LT and GET at 45%–74% of the maximal oxygen uptake (VO2max). Training at or above these thresholds improves aerobic performance.
In contrast, in rats, LT has been identified, but GET is not known yet. Furthermore, it is unclear whether the rat GET and LT can be useful indicators of exercise intensity similar to the thresholds in humans.
The researchers previously established a rat model for identifying the LT during running exercise. This study aimed to simultaneously identify LT and GET by integrating this LT model with the standard human GET identification method, known as the V-slope method.
Subsequently, the relationships among the identified GET, LT, and VO2max, as well as the changes in these thresholds following aerobic training below or above the LT, were examined. The results showed that GET and LT in rats occurred synchronously at intensities ranging from 41.0% to 65.5% VO2max, and that the maximal (VO2max) and submaximal (GET, LT) aerobic capacities were enhanced only in rats that trained at intensities above the LT.
These results suggest that the GET and LT in rats are valid indices of moderate-intensity exercise in training prescription to enhance aerobic performance as in humans. The findings of this study are expected to serve as a catalyst for further research in the field of rat studies focused on exercise intensity, ultimately contributing to the advancement of human exercise prescription strategies. In particular, the noninvasive and easily identifiable nature of the GET from the exhaled gas suggests a wide range of potential applications.

My Exercise Bike Cuts Me No Slack: Peloton Cross Training Bike+ Review
We may earn a commission for purchases using our links. Learn more.
If you told me a few years ago that my exercise bike would be judging my squat form, I would have laughed. But here we are!
Admittedly I could go deeper on those goblet squats so the judgement it warranted.
The home fitness world is crowded. And what works for one person may not fit the lifestyle of another. Any company trying to make a device that supports people new on their fitness journey while also supporting fitness fanatics are faced with some pretty tough challenges to apepel to both crowds.

Peloton is using AI and fusing their experience across devices to create what might be the ultimate home fitness studio experience with the brand new Peloton Cross Training Bike+.
I’ve been testing the new Peloton Bike+ with Peloton IQ for a few weeks now, and if you’re wondering if AI can actually make you fitter (or just make you feel guilty about your form), you’re in the right place.

Peloton’s latest fitness bike is truly their greatest. The instant feedback on your form during workouts and sturdiness of the hardware, all in a relatively small footprint, make this a solid pick for anyone who likes to stay fit in the comfort of their own home.
What is Peloton IQ?
The biggest feature differentiating this bike from the older bike is the AI-powered smarts. Peloton IQ is essentially the brain inside the new Bike+. It uses the new built-in camera and some clever AI to track what you are doing—not just on the bike, but for any workout you do using the sprawling swivel screen.
Source: geekingout.ca
Peloton IQ is a prime example of AI that doesn’t suck
If you’ve ever done a home workout and wondered, “Am I doing this lunge right?” or “Did I actually do 10 reps or did I zone out and stop at 6?”, this is for you.
- Form Feedback: During strength classes, the camera watches your movement and gives you real-time corrections. It’s not nagging; it’s helpful. Especially if you’re losing steam by the end of a long workout and your form/posture is strting to get sloppy. It reminds you (and helps you) finish strong.
- Rep Tracking: No more counting! The system automatically tallies your reps so you can focus on breathing and not dying. Occasionally it misses a rep (like in a strength workout maybe twice), but it’s surprisingly consistent. And if you beat your reps in a strenth workout, it will suggest you increase the weight.
- Personalized Plans: The IQ system looks at your history and goals to suggest what you should do next. It takes the “what workout should I do today?” paralysis out of the equation. This is super important because some days getting the will power to exercise is tough, so it’s one less thing you have to think about.

Particularly in the last year, I’ve gotten pretty deep into learning about AI, large language models, agentic AI, cloud computing and more. From my knowledge and experience, I think Peloton is doing AI “right” for a lot of reasons. But the main one is all the AI stuff is happening on the bike, and not in the cloud.
Don’t be freaked out by the camera. The benefits of Peloton IQ are worth it.
Source: geekingout.ca
If you have a camera pointing at you during a workout, that’s a vulnerable place to be. So you can have some extra peace of mind knowing that video is staying in your home, and not streaming, even for a few seconds, to a cloud server to quickly analyze your form, and then send you suggestions back.
On device AI is fast and private, which is exactly what you want for your workout. But if you just don’t want the Peloton IQ support on a certain day, you can always retract the camera back into the screen.

2025 Peloton Bike+ Hardware Explained
The physical design of the hardware was dialed in with the previous generation, so the smarts are the biggest change, not the design when looking at the new edition of the Bike+. But there are a few nuanced changes.
Source: geekingout.ca
The Swivel Screen
The 23.8-inch HD touchscreen now rotates 360 degrees. This sounds simple, but it changes everything. You can hop off the bike, spin the screen around, and roll out your yoga mat. It turns the bike from just a cycling machine into a full home gym hub.
Sound by Sonos
Peloton partnered with Sonos for the audio system, and you can tell. The front-facing speakers and rear-facing woofers make the music and instructor’s voice crystal clear. When you’re in a heavy climb and the beat drops, that immersive sound actually helps push you through.
Auto-Resistance
This is a feature that was on the previous Bike+ that carried through to the new one. But if you’re coming from a non “plus” Peloton, it’s a game changer. On the base bike, you had to manually twist the red knob every time the instructor called out a change. With “Auto-Follow,” the Bike+ automatically adjusts the resistance to match the instructor’s callouts.
You can still adjust it manually if you need a break. Which, I’ll be honest, on some of those climbs, I do. At least if I notice my heart rate zone is passing from beneficial, to unnecessary stress.
Source: geekingout.ca
The Riding Experience
Riding the Bike+ feels premium. It’s nearly silent (great for early morning rides while the family sleeps), stable, and smooth.
Source: geekingout.ca
When you combine the hardware with the software and your existing tech the experience is even better. The integration of Apple Watch (via GymKit) means your heart rate connects instantly. The new “Cardio Performance Estimates” give you a heads-up on how hard a class is going to be for you specifically, based on your past performance. Overall the metrics on this bike are deeper than what you’d get on the “old” model.
It feels less like you are following a video and more like you are in a private training session.
Is the new Peloton Bike+ Worth It?
This is not a cheap piece of equipment. Between the hardware cost and the monthly All-Access Membership, it’s a commitment.
I feel very strongly that you need to do what works for you and makes sense for you. There’s so many different motivations for wanting to get fit. And there’s so many unique and “smart” (in the tech sense) ways to do it.

The newest Peloton bikes are incredibly smart which is going to make all the difference in hitting your fitness goals. For cycling workouts, it can automatically adjust the difficulty during classes based on coaches recommendations. But the real magic happens in strength workouts (done on the swivelling built-in display). The new screens are powered by Peloton IQ which can analyze and offer suggestions to correct your form during exercise.
My personal opinion is that the quality of classes in Peloton is the very pinnacle of what’s available and, for me, they work very well.
Source: geekingout.ca
I’m coming at this though, from the benefit of having had some quality personal training sessions over the years with excellent in-person instructors who taught me some more advanced techniques. And the “good stuff” I remember from those IRL classes where you’re exhausted but feel stronger is present for me at the end of every Peloton workout.
But this is so personal. Apple Fitness+ has GREAT instructors and I think is a little easier entry point (and is much cheaper especially if you bundle with Apple One). I feel like Fitbit Premium has some good ideas and integrates beautifully with their Fitbit/Pixel hardware, but their interface is just way too chaotic and busy, so that can be a barrier when you’re trying to figure out a daily class or a larger-scale program. Vitruvian is awesome, but that’s just for strength and the hardware and membership are also super expensive.
Source: geekingout.ca
I mention all these other options becuase those are some of the other brands I think you should research before making a committment to smart fitness hardware. Because even though we don’t know each other, if you’re at this point in the article, you must have a serious level of interest in your personal fitness, and I want to see you succeed.
I’d suggest the Peloton Bike + for anyone who:
- Has tried other fitness programs and wants to take things to “the next level”
- Would be motivated by the fact that “I spent thousands of dollars on this thing so I’m gonna use it.”
- Wants the VERY BEST fitness and coaching classes and programs (where a program is a long-term collection of classes designed around specific goals)
- Recognizes that strength training is an essential part of the overall fitness mix (not just cardio)
- Would benefit from an AI note to improve your form, add weight, or track your metrics and progress over time

If you just want to spin your legs and sweat, the original Peloton Bike is great. If you’re wishy washy about your fitness comttiment and don’t see yourself making exercise part of your daily routine, it’s likely not worth the investmnet.
But if you want a personal trainer that lives in your spare room (and doesn’t judge you for sweating in your pajamas), the Bike+ is a fantastic upgrade. It may be one of the best investments you make in your entire life.

Move Over, Aches and Pains: 11 Best Yoga Stretches For Easing Tightness, Tension, and Stiffness
I’m getting old.
Well, I’m not, not really. But as I creep further into my late twenties, the aches and pains are starting to feel worthy of someone beyond my years. They’ve even become a running dinner table topic amongst my friends. Each of us seems to have acquired a niggle, a dodgy joint or a pulled muscle we can compare over pasta, right alongside our new obsessions with homeware and the unexpected thrill of a good vacuum cleaner.
Which is to say: we’ve officially graduated to caring about things we never used to. Including, crucially, the underrated power of a proper stretch.
If you’re still at the stage where you can finish a long run and wake up the next morning without achy knees or stiff hips, then allow me to share a small pearl of wisdom: start stretching now. A regular yoga practice (especially one with slow, deep holds) will buy you more years before you join the rest of us moaning about our backs on a Friday night. And if you’re already here? Rejoice. Because below, two top yoga teachers share the poses they rely on most to ease tightness, tension and all-around stiffness.
It’s pure indulgence for your body and mind. Read on, and thank me later. And once you’re done, don’t miss our guides to yoga for relaxation, yoga for flexibility, yoga for lower back pain, plus the best 10-minute yoga workouts, best 20 minute-yoga workouts, and best yoga flows for core strength, here.
Yoga Is A Failsafe Way To Ease Tension and Tightness. 11 Stretches To Try
Why is stretching important?
First, a reminder that yoga is about far more than stretching or flexibility, and the physical poses aren’t the end goal. “They’re a gateway into presence, connection and self-awareness,” says Yoga Instructor Sophie Rumble.
Still, the stretches we practise in yoga do play a big role in supporting physical and emotional health. One 2021 study found that just ten yoga sessions were enough to improve women’s flexibility, whilst another found that a twelve-week yoga course increased levels of the calming amino acid GABA, which correlated with boosts in mood and reductions in anxiety.
Think of stretching like oiling the bolts on a door or engine. “Most people sit around for six hours a day, which leads to shortened hip flexors, weakened glutes, limited thoracic rotation and stiff fascia,” explains Sarah Drai, Holistic Wellness Retreat Leader and Yoga Teacher at HOME. “Without regular stretching, the muscles become short and tight, which means they’re unable to extend fully when called upon for movement, which increases the risk of joint pain, strains and muscle damage.”
By counteracting the positions we repeat all day, whether sitting, scrolling or commuting, stretching supports posture, hydrates joints, protects our range of motion and keeps muscles supple. “The flexibility which comes from regular stretching also improves circulation and balance,” adds Drai. “Ultimately stretching supports overall movement longevity by minimising the risk that we’ll develop aches, injuries or poor posture.”
What’s the best form of yoga for stretching and flexibility?
The good news: almost any form of yoga will help. “Even when the stretch is dynamic, the muscle is still lengthening and releasing,” explains Drai, which means faster flowing practices like vinyasa still offer strong benefits.
But if you’re after a really profound release, yin yoga will be your best friend. “Each pose is held for three to five minutes,” says Drai, explaining that this “allows you to ground into the pose, releasing tension stored in the connective tissue.” For an even deeper experience, try warm yin. “Warm yin yoga combines the meditative quality of the long holds with the grounding element of heat, which deepens the stretch and creates a profoundly calming experience,” she says.
How long should you hold your stretches for?
A few minutes feel longer than the 60 seconds you’re waiting for the kettle to boil, or the first 60 seconds of a stretch. That initial phase before your body softens can feel painstaking, especially if (like me) you possess a brain that’s always halfway into the next task.
But if you can stick with it, that’s when you really see results. “Consistency is even more important than the length of the hold,” says Drai, who says that even thirty-second holds will help to increase your range of motion.
Yoga instructor and breathwork coach, Jenny Haynes, agrees. “The length of time you hold your stretch really depends on your goal,” she explains. “When warming up before a training session, flowing through some dynamic stretches can be really beneficial, whereas for a deeper release, you should work on holding for longer.”
She’s right. For really significant improvements to flexibility, Rumble says that holding a stretch for between one and two minutes is best. “It’s important not to force the stretch or hold your breath, though,” she reminds us, adding that this is where a yin-style yoga practice, with its breathwork cues, can be really helpful in deepening the stretch.
11 best yoga stretches to relieve tension, tightness, and stiffness
1. Supported Bridge
What? “Start on your back with your knees bent,” says Drai. “Gently raise your hips and place a block or bolster beneath your pelvis.”
Why? “The pose is excellent for stretching the hip flexors, which are shortened by our sitting position in a chair all day,” explains Drai, who adds that it also stretches the lumbar spine and neck.
How long? 2-5 minutes.
Watch On
2. Pigeon Stretch
What? “Start kneeling or in downward dog, bringing one knee forward to the opposite wrist,” says Haynes. “Extend the other leg behind you and try to keep your hips centre.”
Why? Great for releasing tension in the lower back, hips and glutes, the pose also increases mobility and flexibility in the hip joint.
How long? 30-60 seconds.
Watch On
3. Wide Leg Forward Fold
What? “Sit with legs wide, feet gently flexed, and fold forward with a long spine, hands resting on the floor, a block or a bolster,” says Rumble. Her top tip? “Keep the fold gentle enough that your jaw and shoulders can stay soft.”
Why? “Ideal if you sit a lot, this stretch opens the whole inner line of the legs, including the inner thighs (adductors), hamstrings and possibly the lower back,” she explains.
How long? 60–90 seconds, and up to 2 minutes in a more yin-style hold.
Watch On
4. Melting Heart Pose
What? “Start on your hands and knees in a tabletop position,” says Drai. “Keep your hips stacked directly over your knees as you walk your hands forward, allowing your chest to melt toward the floor. Your forehead can rest on the ground. Let your heart sink heavy toward the earth.”
Why? “Providing a deep stretch for the shoulders, chest, and thoracic spine, this pose also relieves the mid-back area that often becomes stiff and immobile from poor posture,” says Drai. “It opens the front body while gently compressing the lower back, creating space in the upper spine.”
How long? 1-2 minutes for beginners. 3-5 minutes if you’re experienced.
Watch On
5. Puppy Pose
What? “Come to an extended child’s pose, kneeling on the ground, sitting your hips back over your heels and stretching your arms forward,” says Haynes. “From there, walk your hands forward and lift your hips up so they’re aligned over your knees. Allow your chest to melt down like a puppy bowing to play, and extend your arms forward until you feel a stretch in the shoulder and chest area.”
Why? One of Haynes’ most requested poses by her students, this offers a “great stretch for the chest and shoulders,” she says.
How long? 30-60 seconds.
Watch On
6. Lizard Lunge
What? A progression from low lunge, this is where “both of your hands come inside the front foot,” explains Rumble. “You can lower the back knee and, if appropriate, come onto your forearms or blocks.”
Why? It’s an intense stretch for the front hip and groin, especially the psoas and hip flexors. “These are classic bracing areas when we’re in fight-or-flight mode. Staying and breathing here can help us unlearn that constant anxiety and urgency, challenging us to be with the sensation rather than distracting from it,” says Rumble
How long? 45–90 seconds each side. “If it’s very intense, start with 5–8 breaths and build up slowly,” says Rumble.
Watch On
7. Reclined Spinal Twist
What? “Start lying on your back with your knees bent and feet flat on the floor,” says Drai. “Draw both knees toward your chest, then let them fall to one side. Turn your head to look away from your knees, or keep it neutral if that feels better for your neck.”
Why? “ This pose stretches the outer hips, lower back, and the muscles between the ribs while gently releasing tension along the entire spine,” explains Drai, adding that “twists are thought to aid digestion and create space between the vertebrae.”
How long? Short hold: 30 seconds. Long hold: 3-5 minutes.
Watch On
8. Downward Dog
What? “Start in a table top position on your hands and knees,” says Haynes. “Walk your hands approximately a hand width distance forward of your shoulders and lift your hips and knees up off the floor, aiming for your hips to draw up and back towards the wall behind you, melting your heels to the ground.
“Don’t worry if your heels don’t touch the floor to begin with,” she adds. “Aim for the line from your wrists to your hips to be as straight as possible, and if that means bending your knees to start, then bend your knees.”
Why? “This is a pose I take almost every day,” says Haynes. “It’s great for opening up tight calves, hamstrings and back, whilst also stretching the shoulders and lats.”
How long? 15-30 seconds.
Watch On
9. Child’s Pose
What? For this pose, you need your “knees wide, big toes together, and your hips sunk back towards your heels,” says Rumble. “Place your forehead on the mat with your arms forward or alongside the body.”
Why? “Incredibly calming for the nervous system, it also gently stretches the hips, lower back and ankles,” Rumble explains.
How long? 1-3 minutes, or longer if it feels good. “Focus on lengthening your exhale as this allows you to drop into your parasympathetic nervous system,” says Rumble.
Watch On
10. Reclined Butterfly
What? “Start seated on your mat, bringing the soles of your feet together and allowing your knees to fall open to the sides, creating a diamond shape with your legs,” explains Drai, who adds that “you can place blocks or folded blankets under each knee for support if your hips are tight.”
Why? “This is a deeply restorative hip opener that also gently opens the chest and heart space, making it ideal for releasing tension accumulated from sitting and stress,” says Drai.
How long? Up to 10 minutes in restorative practices.
Watch On
11. Seated Neck Release
What? “Find a comfortable seated position, and allow your head to drop to the left side, with your left ear melting towards your left shoulder,” says Haynes. She says this can often be enough, but for more of a stretch, “reach your opposite hand over your head and encourage the stretch to deepen.”
Why? “This simple stretch is great for relieving tension in your neck and shoulders, and letting any stress from the day melt away,” says Haynes.
How long? 30 seconds.

Can you overstretch?
Absolutely, and more isn’t always better. “It’s not a problem to stretch every day,” says Yoga instructor and breathwork coach, Jenny Haynes. “But problems can arise when we push too hard or for too long.”
Your stretch can be challenging, but it should never feel like you’re forcing your body to its limits. “We’re always looking for an element of ease,” she says. “If in doubt, tune into your breath. If it’s harsh or jagged, you’re probably pushing too hard.”
“Flexibility is a nice byproduct of yoga,” adds yoga instructor Sophie Rumble. “But yoga isn’t only for the super bendy, despite what you might see on Instagram.” Her parting thought? “You don’t need to be flexible to start; you come to the mat exactly as you are. Over time, your body will usually open and soften, but the real shifts are in how you breathe, how you relate to yourself and how you move through your life off the mat.”

Fitness Experts Share Their Number-1 Aerobic Exercise Tip for Longevity
As strength-training after the age of 50 has been steadily rising in popularity in recent years, love for traditional cardiovascular or aerobic exercise has been on the decline. Still, making this form of exercise a regular part of your routine is just as important to maintaining your vitality as you age—and following the below aerobic exercise tips for 50 plus can help you get the most out of every session.
According to the Cleveland Clinic, aerobic exercise is any activity that you do continuously that increases your heart rate, such as walking, jogging, cycling, swimming, or dancing. “Regular aerobic activity helps mitigate risks like cardiovascular disease, insulin resistance, and bone density loss by improving heart health, managing body composition, enhancing insulin sensitivity, and reducing systemic inflammation,” said Mark Kovacs, Ph.D., C.S.C.S., a human performance scientist and longevity expert.
These benefits become especially important during and after menopause, when your risk of developing osteoporosis and heart disease go up. “Estrogen helps keep blood vessels flexible and cholesterol levels in check,” explained Brooke Bussard, M.D., a certified personal trainer and owner of Brooke’s Balanced Blueprint, a lifestyle medicine health coaching practice in Baltimore, MD. “When estrogen drops, regular aerobic exercise helps pick up the slack by keeping your circulatory system healthy.”
In fact, adults at 50 with ideal cardiovascular health are expected to live an additional 36.2 years, on average, while adults with poor cardiovascular health were only expected to live an additional 27.3 years, according to a 2023 study in the journal Circulation.
Meet the experts: Mark Kovacs, Ph.D., C.S.C.S., is a human performance scientist and longevity expert. Brooke Bussard, M.D., is a certified personal trainer and owner of Brooke’s Balanced Blueprint, a lifestyle medicine health coaching practice in Baltimore, MD.
The best part? You don’t need to run marathons or swim hundreds of laps to get the benefits. You don’t need to be an experienced exerciser either. So whether you’re just getting started or looking for ways to mix up your exercise regimen, these expert-backed tips will help you feel better and healthier for years to come.
Just be sure to check with your doctor before starting a new fitness routine, especially if you have high blood pressure or any heart problems, including heart disease. And if you feel off while exercising, get medical help right away.
How to get the most out of aerobic exercise at 50 plus
1. Aim for 150 minutes a week—but break it into small chunks.
The CDC recommends 150 minutes of moderate-intensity aerobic activity per week. But “this is a minimum recommendation,” said Kovacs: People who worked out two to four times above the moderate physical activity recommendations (about 300 to 599 minutes each week) saw the most benefit in a 2022 study published in Circulation.
Still, something is better than nothing. “The best plan is the one you can stick with,” said Dr. Bussard, who recommends walking for about 30 minutes five times a week. If three 10-minute dance breaks a day works better for you, that’s cool, too. It all adds up—and workouts of less than 10 minutes still count toward recommended weekly activity goals, according to the CDC.
2. Use the talk test to measure your intensity.
Not sure if you’re working hard enough for your activity to count as a workout? Try talking. “For heart-healthy aerobic exercise, you should be slightly breathless but still able to hold a conversation,” said Dr. Bussard.
You can also determine intensity using a scale from 1 to 10. “Moderate intensity (like a brisk walk or steady cycling) typically corresponds to a five or six out of 10 on the effort scale,” said Kovacs, “while vigorous aerobic exercise (fast walking uphill or jogging) should feel like a seven to eight out of 10, where talking becomes difficult.”
3. Don’t count out low-impact activities.
Cycling, elliptical training, swimming, or walking on an incline are all joint-friendly ways to raise your heart rate. “These options reduce joint stress, which is critical as cartilage, tendons, and ligaments may become less resilient with age,” said Kovacs.
But “low-impact doesn’t mean low-intensity,” said Dr. Bussard. “You can absolutely work up a sweat and challenge your heart and lungs without pounding your joints.” Just pay attention to the effort you’re exerting in the moment and aim to hit that five out of 10.
4. Work in short, quick bursts.
“Adding short bursts of faster-paced intervals to your aerobic routine boosts the benefits,” said Dr. Bussard, as long as you’re cleared by your doctor to work harder. Recent research in the journal Lipids in Health and Disease shows that high-intensity interval training (HIIT) can improve insulin sensitivity, blood pressure, and overall fitness—“all areas that can decline during menopause,” she added.
This kind of training is considered vigorous activity, so you don’t need as much of it: Just two HIIT sessions per week (with a total training time of 20 minutes per workout) improved working memory and lower-body muscle function more than moderate-intensity continuous cycling, and boosted cardiorespiratory fitness just as much, according to a 2023 study published in The Journals of Gerontology.
5. Mix up your workouts.
Boredom is the enemy of consistency. Try different types of cardio—like hiking, aqua aerobics, Zumba, or even pickleball. “Varying modalities challenges different muscle groups, reduces overuse injury risk, and improves neuromuscular coordination,” said Kovacs. “It also helps sustain motivation and supports functional aging by preparing the body for a wider range of physical challenges.”
6. Let your body recover.
As you age, your body may take longer to bounce back. “Recovery between workouts often takes longer due to a combination of physiological changes,” said Kovacs. “These include slower muscle protein synthesis, reduced hormone levels (like estrogen and growth hormone), and less efficient mitochondrial function—all of which contribute to slower tissue repair and reduced energy availability.”
Make sure to allow 48 to 72 hours of muscle recovery between higher-intensity sessions, and prioritize adequate sleep, sufficient nutrition, and active recovery, like gentle walking or mobility work. And listen to your body; if you feel wiped out for days, scale back and allow more rest between sessions.
7. Take the time to warm up.
Older muscles and joints need more prep. “As estrogen drops, tendons and ligaments get stiffer, so warming up is more important than ever to prevent injuries,” said Dr. Bussard. “A good warm-up should move your joints through a full range of motion and activate your major muscles.” Try inchworms, bodyweight squats with overhead reaches, and side-to-side lunges—just five to 10 minutes can prime your body for exercise.
8. Pair cardio with strength-training.
Women over 50 benefit most when they combine cardio and strength-training, as both play essential but distinct roles in healthy aging. “Aerobic exercise keeps your heart healthy, but you need strength training to keep your muscles and bones strong,” said Dr. Bussard. Putting them together is the real key. “Combined, they form the foundation of long-term healthspan and mobility,” said Kovacs.
