Most adults over 70 face a difficult body-composition challenge: they need to lose fat, but losing muscle is dangerous, and standard aerobic exercise and even some forms of strength training may contribute to both.
A six-month randomized study of more than 120 healthy adults averaging 72 years old has identified a specific solution. Published in Maturitas by researchers at the University of the Sunshine Coast (UniSC) and the University of Queensland in Australia, the study found that high-intensity interval training (HIIT) was the only exercise modality that consistently reduced body fat percentage while maintaining lean muscle mass.
