Recent research has shown that high-intensity interval training (HIIT) may actually reduce and reverse longterm damage done to mitochondria—the powerhouse of the cell.
Those who practiced HIIT had increased numbers and health in their mitochondria, which, long term, can actually slow cellular aging.
HIIT involves doing a particular exercise at 100 percent effort for short bursts of time (30 seconds-3 minutes), usually with 30 second rest periods in between. Generally, workouts range between 10-30 minutes.
