Only one workout helped older adults lose fat and keep muscle

Perspective
I’m cautious about generalizing these results to all older adults, since the study reports only an overall benefit of HIIT.
Source summary
A six-month study suggests that high-intensity interval training (HIIT) may offer older adults a powerful advantage: losing body fat while keeping their muscle. Unlike moderate-intensity workouts, which led to a small loss of lean muscle, HIIT preserved it while also improving body composition around the waist.
