Compared to sitting all day, any exercise is better than none. But if you’re determined to ward off an early death, one form of exercise, called high-intensity interval training (HIIT), may give you a leg up.

It sounds technical, but it’s not. HIIT is basically any workout – on a bike, in the pool, on the pavement – that alternates quick bursts of intense exertion with short intervals at a moderate pace.This approach to exercise puts the brakes on important markers of aging at the cellular level, researchers say.

In a study published last month in the journal Cell Metabolism, sedentary volunteers who did high-intensity interval training showed increased activity in their mitochondria, the energy powerhouses in our cells. Mitochondria are like tiny digestive systems, converting nutrients from food into the main energy source for most of a cell’s functions.

After 12 weeks of HIIT workouts, study volunteers between the ages of 18 and 30 saw a 49-per-cent boost in their mitochondrial capacity, while the 65- to 80-year-old group saw an increase of 69 per cent. #novuscenter #antiaging #HIIT
