Start by holding a pair of 5-lb. dumbbells in each hand at shoulder height. With feet hip distance apart, slowly start to sink into your heels, lowering into a squat.
When you get to the bottom of the squat, power up, drive your hips forward and engage your glutes as you straighten your legs back to standing. At the same time, press your dumbbells above your head into a shoulder press.
Squat back down a second time, and this time as you come up, keep your dumbbells at shoulder height and push off your glutes into a squat jump.
Lower back into a squat and repeat. Alternate between a squat press and squat jump, repeating each 10 times for one complete circuit. Perform the circuit twice.
