Asparagus extract shows synergistic effects with exercise for improved heart fitness
Researchers in Thailand explored the effects of Asparagus officinalis supplementation alongside HIIT to investigate whether the two could work synergistically.
They reported that the combination “has the potential to improve cardiovascular and respiratory function and serve as a preventive strategy against cardiovascular and respiratory disorders in obese and overweight individuals.”
Botanical extract for cardiovascular health
High-intensity intermittent training (HIIT), which involves short bursts of intense exercise and recovery periods, has been found to improve muscle performance and cardiopulmonary fitness. However, little research has evaluated its impact on cardiovascular and pulmonary function in obese individuals, according to the researchers of the new study.
Ecdysteroids (arthropod steroid hormones) have demonstrated anabolic, fat-reducing, anti-inflammatory and cardioprotective properties, and 20-hydroxyecdysone (20E), which comes from Asparagus officinalis, has been shown to improve physical performance and muscle strength in healthy populations.
Previous studies have found that 20E supplementation reduced body weight, fat, cholesterol and inflammation, and improved muscle strength and bone health in obese individuals. However, the researchers noted that no previous studies have explored the combined effects of HIIT and 20E supplementation on cardiovascular and pulmonary function in obese and overweight individuals.

Study details
The researchers recruited 72 obese and overweight male and female participants between the ages of 18 and 30 with a BMI over 22.9 kg/m². They were randomized into four groups: the control group, the HIIT group, the AOE (A. officinalis extract) group which received 1.71 mg/kg/day, and the combined HIIT and AOE group. The HIIT Program consisted of three sessions a week, and participants in the AOE and HIIT and AOE groups received capsules and logged their intake twice daily via an app.
The researchers assessed heart rate (HR), HR variability, endothelial function, blood pressure (BP), BP variability, pulmonary function and volume, respiratory muscle strength, chest expansion and body composition at the beginning of the trial and 12 weeks post-intervention.
Results indicated that combining HIIT with 20E supplementation improved heart rate variability, endothelial function andexpiratory muscle strength after 12 weeks, which in turn was found to benefit lung function and exhalation.
While the 20E group did not experience any significant changes, the researchers suggested that 20E can support molecular pathways related to protein synthesis, inflammation reduction and cardiovascular protection. These effects were more pronounced in the HIIT and AOE group, where the systems activated by the exercise potentially allowed 20E to further improve muscle remodeling, vascular function and autonomic regulation.
The HIIT and AOE groups also showed increased blood flow and enhanced vascular responsiveness, and in comparison to the HIIT group, they showed improved vasodilation, allowing for increased blood flow to tissues. The 20E group did not display significant signs of improved endothelial function.
Resting blood pressure (BP) significantly decreased only in the HIIT group, however, the researchers noted that 20E appeared to reduce BP variability further when combined with HIIT, “suggesting a synergistic effect that may help reduce BP variability”.
“A 12-week HIIT program combined with A. officinalis extract supplementation improved HR variability indices, potentially lowering cardiovascular disease and atherosclerosis risk via increased endothelial function,” the researchers concluded.
“It also enhanced expiratory muscle strength, lower-chest wall expansion and, consequently, pulmonary function. The clinical implication is that utilizing HIIT in conjunction with supplementation with A. officinalis extract containing 20E at 1.71 ± 0.24 mg/kg/day daily for 12 weeks is safe and could be an option for individuals who are obese or overweight.”
They added that future research should assess blood lipid profiles, blood glucose levels and inflammatory markers in order to gain a better understanding of the mechanisms of action.

The NHS has reignited the hybrid working debate – but WFH isn’t the health risk, this is
The latest NHS exercise guidance reinforces what we’ve been preaching for years: hitting that 150-minute weekly movement target isn’t necessarily a get-out-of-jail-free card. It states that prolonged sedentary time is independently harmful, even for those of us who diligently carve out time for the gym. Verbatim, it says ‘prolonged sitting is harmful, even in people who achieve the recommended levels of moderate to vigorous physical activity’.
Chief Medical Officer Professor Sir Chris Whitty has been especially vocal about how detrimental it could be, highlighting hybrid working as a potential health hazard. ‘Without wanting to exaggerate, I think it’s important people think through, for example, hybrid working means quite a lot of people could very easily do very little other than leave their homes, where previously people would be routinely going to work, and that often meant at least some physical [activity],’ he said at a briefing.
I understand his logic, but it’s pretty reductive. Working from home isn’t the villain here – working from one chair is.
When we label remote work as “bad for your health”, we risk throwing the baby out with the bath water. In reality, for many – certainly the whole of the Women’s Health office, but also my less-fitness-conscious sister and stepdad, plus my entire friendship group – working from home often means being more active. It means more time to fit in a lunchtime run, to get some steps in before work, or to run some errands on a quick break.
On the other hand, plenty of office workers are more sedentary than they are at home. They sit at a desk for nine hours straight before driving home, whether to be seen to work tirelessly in front of their manager, or simply because they’re pulled from pillar to post in an office setting. For those who do have an office commute, eliminating that often stressful period of the day allows for better sleep, and more time for the movement breaks we need to break up the dreaded sedentary time. Not to mention that many commutes are almost entirely sedentary on a train/tube/bus.
The potential problem, the advice suggests, is the lack of incidental movement – the walk to the train, the stroll to a meeting room, or heading out for lunch – that’s naturally baked into your day when you’re in the “official” office. Without a commute or a day in the office, the onus is on you to manufacture movement in.
Without sounding evangelical, I’ve made this a non-negotiable part of my day. On WFH days, I work out or walk every single morning before I log on, and walk again every evening, even if just a lap around the block. During the day, I have a personal rule: if I’m downstairs, I use the upstairs toilet (and vice versa). Sounds excessive, but it forces me to activate my muscles and add to my step count every few hours.
Beyond that, the options are endless if you’re intentional. Use a standing desk or put your laptop on a kitchen worktop during calls. Take every phone meeting on foot, pacing your hallway if necessary. Set a timer to stand up every 30 mins to stretch, grab a glass of water, or do a quick load of laundry.
We don’t need to return to the office to be healthy; we need to bring movement back into our homes. The goal: to stop being professional sitters.

A Strength Coach Says These Two Exercises Are All You Need to Build Stronger Shoulders
If you ask anyone on the gym floor how to grow a bigger set of shoulders, you’ll probably find that no two answers are the same. In between front raises, upright rows, machine presses and cable raises, shoulder day can quickly become a long list of exercises.
However, fitness creator and coach Eric Evans, also known on social media as Average to Jacked, thinks most lifters are overcomplicating things. He says that if he had to start from scratch after over a decade of training, he’d strip his shoulder workouts back to just two simple moves.
‘If I had to start over today, I’d build my shoulders with just two movements: a lateral raise and also a rear delt fly,’ he explains.
According to Evans, the reason for this isn’t because those exact exercises are magic, but because they work the correct movement pattern for the muscle.
‘Your body doesn’t know the name of the exercise you’re doing,’ he argues. ‘It really only knows the fundamental movement pattern you’re asking it to perform and also the amount of tension you’re placing on the muscle.’
So, you don’t have to perform cable lateral raises if your gym only has dumbbells, or use a reverse pec deck if you’d rather do bent-over rear delt flyes. As long as you’re training the same movement pattern and progressing the move with intensity or volume, you’ll achieve a similar result.
According to the coach, lateral raises deserve a place in your programme because they primarily target the side delts, helping create broader-looking shoulders and a more pronounced ‘V-taper’. Rear delt flyes train the back of the shoulders to create a rounder, more 3D physique.
‘I’m not including anything for the front delts, and that’s intentional,’ he says. ‘Your front delts are already heavily involved every time you do pressing exercises for your chest.’
For most lifters already bench pressing, incline pressing or overhead pressing regularly, he argues the side and rear delts are more likely to be the limiting factor.
‘I don’t think the front delts are what’s holding their shoulders back. I think it’s the side and rear delts,’ he adds.
He recommends focusing on controlling every rep, and avoiding using momentum to swing the weight. He also suggests working in the 8-15 rep range, adding reps until you reach the top of the range before increasing the load and repeating the process – also known as progressive overload.
‘You definitely don’t need to hit your shoulders from 10 different angles,’ he says. ‘You just need to consistently train these two movement patterns, push them hard and then gradually get stronger over time.’
The Bottom Line
Research suggests muscle growth is driven more by sufficient training volume, progressive overload and proximity to failure than by constantly changing exercises and programme hopping. In fact, that could hinder it. So if your shoulder workouts have become jam-packed with unnecessary variations, simplifying your approach may be exactly what helps you make more consistent progress in the long term.

80-year-old fitness icon Joan MacDonald reveals her simple exercise for a stronger, more stable core
Joan MacDonald didn’t enter a gym until she was 70. Really. Since then, the 80-year-old has transformed her health by losing three stone and building significant muscle, and now coaches other women through her training platform, Train With Joan, which she launched to help others boost their fitness at any age.
The premise of her app is simple: minimal-equipment workouts built around no-fuss, effective exercises that can be done anywhere. One ‘powerful core and stability exercise’ she swears by is alternating bodyweight clock taps. ‘This movement helps strengthen the muscles that keep you stable, balanced and moving well as you age,’ Joan explains.
Bodyweight clock taps benefits
Think they look too simple? That’s the point. Joan is adamant that ‘You don’t need complicated workouts to start getting stronger. Sometimes the most effective movements are the simple ones you do consistently.’
According to Joan, regularly performing bodyweight clock taps help:
- ‘Strengthen your core which supports your spine and reduces strain on your lower back.
- ‘Improve balance and coordination, helping you stay steady on your feet.
- ‘Increase hip stability, which supports your knees and joints.
- ‘Build functional strength for everyday movements like stepping, turning and reaching.
- ‘Help reduce fall risk by improving control and body awareness’
How to do bodyweight clock taps
Find a demo from Joan above, along with instructions for how to do them with proper form below.
- Stand on one leg with a slight bend in your supporting knee and brace your core.
- Keeping your hips level, reach your free foot forward to lightly tap the floor in front of you (12 o’clock), then return to the centre.
- Continue tapping to different “clock” positions—such as 3, 6 and 9 o’clock—maintaining your balance and control throughout.
- Complete all reps on one leg before switching sides.
Form tip: Move slowly and focus on staying stable. The goal is controlled movement, not how far you can reach.
How many reps and sets to do
Joan shares her advice, according to your fitness level.
- Beginners: ‘3 taps per leg x 8-10 reps’
- Intermediate: ‘3 taps per leg x 10-12 reps’
- Advanced: ‘3 taps per leg x 12-15 reps’
