Age-defying effects of high-intensity interval training

Any exercise is good for your health, but a recent study published in the journal Cell Metabolism found that high-intensity interval training, also known as HIIT, can improve age-related changes in a person's cells.

As we age, our ability to produce protein and develop muscles declines. But New York Sports Clubs personal trainer Edem Tsakpoe says HIIT helps you produce enzymes to slow that decline.

He says doing HIIT has many benefits, including for your heart. It is great at developing aerobic and anaerobic cardiovascular capacity because it taxes your heart and lungs. High-intensity interval training also increases your metabolism and can make you feel more euphoric, he says.

If you have never done HIIT before, you can start with a 4-minute workout. Then gradually build up endurance for 30- to 45-minute workouts.
