The Best Gadgets to Make You Slim
The best tool for a strong chest: Medicine ball
Strong-chest move: Roll-the-Ball with Uneven Push-Up
Here's why: "Stabilizing yourself on the balland rolling it back and forthrequires you to engage all of your chest muscles, including the smaller ones that often get bypassed," McGee explains. "And a medicine ball is the perfect size for push-ups." The unevenness of the push-up also helps balance out your strength by not allowing your stronger side to compensate for your weaker one. Plus, the position targets the underside of your chest, helping give the girls a lift.
