How long do you have to exercise for it to count? – Times of India
The minimum effective dose: 150 minutes a week
The World Health Organization (WHO) and the American Heart Association (AHA) recommend at least 150 minutes of moderate-intensity aerobic exercise per week. This translates to just 30 minutes a day, five days a week. If you prefer more vigorous activities, like running or high-intensity interval training (HIIT), the recommendation drops to 75 minutes per week.
Research supports these guidelines, showing that even this “minimum effective dose” of exercise can significantly reduce the risk of chronic diseases such as heart disease, diabetes, and certain cancers. A 2019 study published in the British Journal of Sports Medicine found that exercising for just 15 minutes a day could extend life expectancy by three years, proving that even short bouts of activity can make a difference.
Quality over quantity: The intensity factor
While the 150-minute rule is a great baseline, it’s not just about how long you exercise but how you do it. Research from the American College of Sports Medicine (ACSM) suggests that higher intensity workouts can provide similar, if not greater, benefits in less time. For instance, 20 minutes of HIIT can burn more calories and improve cardiovascular fitness more effectively than a 40-minute steady-state cardio session.
6 best evening workouts for weight loss, better sleep
The key is to find a balance between intensity and duration that works for your body and fitness level. A mix of moderate and vigorous activities can help you meet your goals without overloading your schedule.
Strength training
Cardio often gets the spotlight, but strength training is equally important. The AHA recommends incorporating muscle-strengthening activities at least two days a week. These sessions don’t have to be long—even 20 to 30 minutes of resistance training can improve muscle mass, bone density, and metabolic health.
A study published in the Journal of Applied Physiology highlighted that just 11 minutes of strength training three times a week could lead to significant improvements in muscle strength. So, whether you’re lifting weights or doing bodyweight exercises, consistency is key to seeing results.
Power of short workouts: Do they really work?
For those with jam-packed schedules, short workouts—sometimes called micro-workouts—can be a game-changer. Recent studies, including one from the Journal of the American Heart Association, have shown that breaking up your exercise into shorter sessions throughout the day can be just as effective as longer workouts.
For example, three 10-minute sessions spread across the day can provide the same cardiovascular benefits as one 30-minute session. These micro-workouts can be anything from brisk walks to quick strength circuits, making it easier to fit exercise into your day.
Listen to your body: Rest and recovery
While it’s tempting to push yourself to exercise more for faster results, rest and recovery are crucial components of a successful fitness routine. Overtraining can lead to injuries, burnout, and even diminish the benefits of your workouts. The ACSM emphasizes the importance of listening to your body and adding rest days to allow muscles to repair and grow stronger.
Experts suggest varying your routine with different types of exercises to avoid overworking the same muscle groups. This approach not only reduces the risk of injury but also keeps your workouts fresh and engaging.

You don't need to go to an in-person exercise class to lower your back pain
Around 39% of adults in the United States deal with back pain, according to the Centers for Disease Control and Prevention. Research shows that lumbar stabilization exercises and stretching and strengthening exercises can help reduce back pain. One of the reasons exercise could be beneficial for diminishing those aches or twinges is because it lowers inflammation. Studies reveal that just 20 minutes of exercise has anti-inflammatory effects. There are different types of exercise, and working out at home is more convenient and affordable, offering you the privacy and comfort of your own space. A new study reveals that a specific type of online exercise class could also help your back pain. Let’s look at the research.
The study
In a study published in Jama Network Open, the researchers categorized patients into two groups:
- Yoga group 1 — participants received virtual hatha yoga classes.
- Waitlist group 2 — participants were on a waitlist for yoga.
The study participants were Cleveland Clinic employee health plan patients in Florida and Ohio. Patients in group 1 were given detailed workbooks and video recordings to help them safely practice yoga at home. The trained teachers demonstrated using supportive props like chairs and blocks to adapt poses when necessary.
The study results
When the study began, the participants reported back pain levels of around 6 out of 10. After six weeks, group 1, who practiced yoga, reported that their pain levels dropped to 4. After six months, pain levels declined to 3. Group 2, who didn’t practice yoga, noted that their pain levels remained the same.
74% of participants were taking some type of pain medicine at the start of the study. Six months on, over half of the patients in the waitlist group were still taking ibuprofen, aspirin, opioids, and other pain medicines. Less than one-third of the yoga group continued taking pain relievers.
Patients with back pain who took 12 weeks of online live-streamed yoga classes also moved more easily and slept better than individuals on the wait list for the classes.
If you’re dealing with chronic back pain, it’s best to consult with your healthcare provider, doctor, or physical therapist to rule out any underlying health problems. It’s possible that for some people, yoga could aggravate certain issues.
The benefits of yoga
Yoga is a meditative movement where you perform specific physical poses and postures while focusing on deep breathing. There are more fast-paced types of yoga that can raise your heart rate higher or slower and gentler practices.
Growing research highlights the many benefits of practicing yoga, such as:
- Lower stress and anxiety.
- Decrease back pain.
- Improve the quality of life in those with chronic conditions.
- Stimulate brain function.
- Help reduce the risk of heart disease.
- Enhance muscular strength and body flexibility.
- Improve sleep.
- Promote and improve cardiovascular and respiratory function.
The takeaway
The study’s senior author noted that pain levels were cut in half when patients practiced yoga. Online yoga classes are more accessible and allow you to be guided by an experienced yoga teacher while still working out from the comfort of your home. You don’t have to travel to attend in-person yoga classes to get the benefits.

Higher Physical Activity Levels Can Increase Life Expectancy
FRIDAY, Nov. 15, 2024 (HealthDay News) — Higher physical activity (PA) levels can increase life expectancy, according to a study published online Nov. 14 in the British Journal of Sports Medicine.
Lennert Veerman, M.D., M.P.H., Ph.D., from the Griffith University School of Medicine and Dentistry in Gold Coast, Australia, and colleagues estimated how much low PA reduces life expectancy by applying a predictive model based on device-measured PA risk estimates and a life-table model analysis among adults aged 40 years and older. In addition, the authors examined how much life expectancy could be improved by increasing PA levels.
The researchers found that Americans older than 40 years could live an extra 5.3 years if all individuals were as active as the top 25 percent of the population. Individuals in the lowest activity quartile had the greatest gain in lifetime per hour of walking, where an additional hour of walking could add 376.3 minutes of life expectancy.
“Higher PA levels provide a substantial increase in population life expectancy. Increased investment in PA promotion and creating PA promoting living environments can promote healthy longevity,” the authors write. “Infrastructure measures that encourage active transport, walkable neighborhoods as well and green spaces might be promising approaches to increase PA and resultant healthy life expectancy at the population level.”
