Engaging in regular High Intensity Interval Training (HIIT) is an effective way to improve your level of fitness while promoting cardiovascular health. A new study published in the journal Medicine & Science in Sports & Exercise suggests there are no age barriers to the benefits of HIIT.

Researchers recruited 72 men and 22 women between the ages of 20 and 70 years old. All exercised the typical amount for their age bracket, and all subjects performed supervised HIIT workouts with a targeted intensity of 90% to 95% of maximum heart rate 3 times a week.

Compared to before the 8-week intervention began, all age groups experienced between 9% and 13% increases in maximal oxygen consumption, an indicator of fitness. These improvements were not significantly different between age groups.
