Why two hours of strength training is the ultimate longevity tool.
If you still think strength training is only for gym fanatics who enjoy lifting heavy objects for fun, it may be time for a rethink. Research from Harvard University, published in the British Journal of Sports Medicine, followed more than 147,000 adults over 30 years and found that just 90 to 120 minutes of strength training a week was linked to a 13 per cent lower risk of premature death, a 19 per cent lower risk of death from heart disease and a 27 per cent lower risk of death from neurological conditions. Interestingly, researchers found that doing more than two hours a week offered no additional longevity benefits, suggesting that when it comes to strength training, a little consistency goes a very long way. Combining resistance exercises such as squats, lunges, press ups and rows with regular aerobic activity delivered the greatest results, with some participants reducing their risk of premature death by as much as 58 per cent.
The benefits extend far beyond adding years to your life. TheAmerican College of Sports Medicine recently reviewed 137 studies involving more than 30,000 people and concluded that strength training improves muscle strength, balance, walking speed, power and everyday function, regardless of age or fitness level. Their advice is refreshingly simple. Two full body strength sessions each week can make a meaningful difference. Experts from the ACSM recommend focusing on fundamental movements such as squats, lunges, pushing, pulling and lifting. Strength training is associated with improved mood, energy levels and a reduced risk of several chronic diseases.
In short, building muscle is not about looking like an action movie star. It is about making everyday life easier, whether that means carrying shopping bags, climbing stairs or getting up from the sofa without making that involuntary noise everyone starts making eventually.
One of the most important reasons to lift weights is that muscle naturally declines with age through a process known as sarcopenia. As muscle strength falls, the risk of falls, fractures and loss of independence rises. Researchers studying healthy ageing have found that maintaining strength helps preserve mobility, balance and resilience during illness or injury. The encouraging news is that it is never too late to start. Studies show that even adults in their seventies and eighties can make significant strength gains when they begin resistance training. That means your muscles are far less interested in your birth certificate than you might imagine.
The biggest mistake people make is assuming they need the perfect programme before they begin. Experts increasingly agree that consistency matters more than complexity. The advise is to start slowly, focus on your personal goals and remember that anything is better than nothing. So whether you begin with a few squats in your living room or a couple of weight sessions each week, the evidence is clear.
Strength training is one of the most powerful investments you can make in your future self, and unlike many health trends, this one comes with decades of research rather than a flashy social media filter.
