Weight Lifting: Less is More
Who's getting the better workout? The woman who quietly does her three sets each of lighter weight lifts? Or the man who piles on the weight and grunts and strains to hoist one enormously heavy set? According to a study reported in the Journal of Applied Sport Science Research involving subjects doing deadlifts, squats, crunches, bench presses, and bent-over rows, the woman would win.
Lifting less weight with more repetitions is better for building muscles and high-intensity endurance, the study found. The advantage of low-weight, high-repetition training was particularly apparent after just seven weeks of exercising, and the benefits intensify when extended over months and years.
