Dynamax Ball

If a stress ball and a medicine ball had a baby, that lovechild would be the Dynamax. This soft, squishy, weighted wonder is big enough to wrap up in a hug-then hurtle against a wall or slam on the ground for a tension-melting workout that melts cals and hones hot muscles.

Go-to move: Squat, toss & catch

All Dynamax balls are 14 inches in diameter, and they can range from 4 to 30 pounds. For Jackson's move below, try a 6- to 8-pounder to start, and upgrade as you get more badass.

Try it: Stand with feet hip-width apart and holding the Dynamax ball in both hands at waist, elbows bent. Squat low, then explosively jump up, simultaneously throwing the ball into the air above your head. Catch it, then return to start and repeat. Do 3 sets of 10 reps.

What it works: Everything! Shoulders, chest, back, abs, butt, legs
