The benefits of sprint interval training

In a paper from June 2021 published in Medicine & Science in Sports & Exercise, sprint intervals performed on a bike improved both muscular and cardiovascular markers in the body. After eight weeks of training three times a week for 15 minutes, participants increased their muscle volume in their thighs, overall muscle mass, neuromuscular power and oxygen consumption. Most impressively, the participants were all aged 50-68, the age at which these markers of health tend to decline.

While there are other ways to increase your muscle mass, Weldon says “the beauty of SIT is in its efficiency. SIT training massively outperforms other styles of training in regards to increasing aerobic fitness and lean muscle mass in a shorter amount of time.”
