New Delhi: You don’t need a gym, fancy equipment or long hours to stay fit. A large global review of studies has found that just two sessions of basic strength exercises per week can make a real difference to your health.Research published in the Journal of the American College of Sports Medicine looked at data from more than 30,000 adults and discovered that simple resistance exercises — such as squats, push-ups, lifting household weights or using resistance bands — can improve muscle strength, balance, walking speed and overall fitness.These aren’t just fitness benefits — they directly affect how easily a person can climb stairs, carry groceries, or avoid falls as they age.The biggest takeaway is how little effort is required to start seeing results. Two short sessions a week, working major muscle groups with moderate effort, are enough – there is no need to push your body to exhaustion or follow complex routines. What matters more is consistency and a gradual increase in difficulty over time.Dr Deepak Joshi, director of the Sports Injury Centre, Safdarjung Hospital, said, “Two days a week is a start, but for real gains in strength and overall health, I recommend patients to aim for at least four days. Even simple, no-equipment routines or yoga can be effective – just 20-25 minutes is enough to cover major muscle groups like the back, knees and hips.”These findings are especially important at a time when many people are sitting for long periods of time and physical activity is decreasing.Weak muscles and poor balance increase the risk of falls, joint problems, and loss of independence later in life. Dr Naman Wahal, Senior Consultant Orthopedics, Fortis Escorts, Delhi, said that in regular practice, many patients who walk regularly still show decreased muscle strength, poor balance and early overload on joints. He added that walking alone does not solve age-related muscle loss and reduced strength contributes to instability, falls and delayed recovery even in people in their 40s and 50s.Experts say almost any form of resistance exercise works, but how it’s done matters.Professor Mandeep Dhillon, director of orthopedic and sports medicine, Fortis Chandigarh, said low-grade weight training helps maintain muscle tone and improve bone mass, especially with age. He cautioned that beginners, especially older adults, should avoid suddenly performing exercises such as push-ups or squats without prior conditioning and should ideally start under supervision in a structured or group setting, while building strength work with walking as an aerobic activity.Despite the obvious benefits, very few people still include strength training in their daily routine. The study highlights this gap as a lost public health opportunity, with evidence showing that even 30–60 minutes a week of muscle-strengthening activity can substantially reduce overall mortality risk, with greater benefits when combined with aerobic exercise.
