Leg strength is often overlooked but plays a crucial role as we age. It helps improve balance, protects the brain, and predicts longevity. Maintaining it is also important for keeping chronic diseases at bay and preventing injuries that may cause more damage than you think.
In one of his recent posts on X, Dr Shraddhey Katiyar explained that leg strength can improve the overall quality of your life. “Strong legs save lives. This isn’t motivation. It’s biology. Your legs are the largest muscle group in the body. When they weaken, everything else follows,” he wrote.
“Leg muscles act as a metabolic sink. Strong quads, glutes, and hamstrings improve insulin sensitivity, lower blood sugar, and reduce the risk of type 2 diabetes. Loss of leg muscle is strongly associated with insulin resistance and metabolic disease,” he said. This is proven by studies, one of which associated low leg muscle strength with a greater risk of diabetes.
After 50, balance becomes a problem, especially when leg muscles are weak. This increases the probability of falls, leading to injuries, disabilities, and deaths in older adults. The doctor explained, “Strong legs mean better balance, faster reflexes, and the ability to recover from a stumble. Weak legs mean fractures, hospital stays, and rapid decline.”

“Multiple cohort studies show that lower body strength is a better predictor of all-cause mortality than hand grip alone. People with stronger legs live longer, independent of age, smoking, or BMI,” Dr Katiyar pointed out. Thus, leg strength plays a crucial role in predicting how long you will live.

When your legs are strong, there’s slower cognitive decline, better body functioning, and a lower risk of dementia. “Leg training increases blood flow, improves mitochondrial function, and releases myokines that reduce inflammation and support brain health. Sarcopenia is linked with higher dementia risk. Walking strength matters more than crossword puzzles.”
Healthy and strong leg muscles determine hospital outcomes. If your lower-body strength is better, it implies faster recovery, better tolerance to illness, and lower ICU mortality. However, the doctor warned, “Bed rest kills muscle first, especially in the legs. Once it’s gone, recovery is slow or never complete.”
Think of everyday activities that require your legs. These include toileting, climbing stairs, getting out of a chair, and catching yourself from a fall, among others. So, if you lose leg strength, you don’t just lose fitness but also your autonomy.
According to Dr Katiyar, training your legs is important for heart health, brain health, and longevity. It is not for aesthetics or sports, but for survival. What should you do? He suggests walking daily, doing squats, climbing stairs, and carrying weight.
