A study with over 120 adults in their 70s showed that high-intensity interval training (HIIT) effectively reduces body fat while preserving muscle mass. Unlike moderate or low-intensity exercise, HIIT maintained lean muscle, which is important for healthy aging. The six-month trial highlighted HIIT's unique benefits in simultaneously improving body composition for older adults.
