Exercise, and in particular high-intensity interval training (HIIT) pushes your cells to make more proteins and this slows the aging process, according to a new study published Tuesday in the journal Cell Metabolism.

Three exercise groups were compared.
1) The high-intensity interval training (HIIT) training group did three days a week of cycling, with high-intensity bouts sandwiched between low-intensity pedaling, and two days a week of moderately difficult treadmill walking.
2) The strength training group performed repetitions targeting both lower and upper body muscles just two days each week.
3) The combined training group cycled (less strenuously than the first group) and lifted weights (fewer repetitions than the second group) for a total of five days a week.

All forms of exercise improved overall fitness. Strength training was most effective for building muscle mass and for improving strength.

With the HIIT group, younger participants saw a 49% increase in mitochondrial capacity, while older participants saw a 69% increase, showing that HIIT is most effective for rejuvenating the body.
