10 Exercise Cheats That Blow Your Calorie Burn
Momentum comes in handy when you're attempting a long jump, but not if you're lifting weights. Each exercise involves two phases: a concentric (contracting) move and an eccentric (stretch) phase. "Building momentum by swinging your arms when doing a move like a bicep curl or a tricep push-down sacrifices results by not controlling the eccentric phase, and also increases your risk of injury, " says Irv Rubenstein, PhD, exercise physiologist and founder of STEPS Fitness, a science-based fitness facility in Nashville, Tenn. Practice a two-second count on the concentric move and four to five count on the eccentric.
