Load One Side to Fire Up Your Core
Your core does more than resemble beer packaging (six-packs for some, kegs for most); it also stabilizes your body. So when you create instability—by holding a weight in one hand, but not in the other, for instance—your middle starts working. "In order to maintain proper posture, your torso muscles have to engage to counterbalance the load," says Nick Tumminello, CSCS, director of Performance University. He recommends this strategy for lunges, squats, and shoulder presses, but his favorite offset load is the standing, single-arm chest press on the cable machine.
