Body-Weight Challenge

Perform the following four moves as a circuit: Do one for 20 seconds, rest for 10 seconds, and then move on to the next. Repeat twice. To increase difficulty, do the exercises for 30 seconds but keep the resting time the same. This finisher will take about five minutes.

1. Speed Squat: With feet hip-width apart, bend your knees to 90 degrees, keeping your chest upright. Return to standing as quickly as possible.

2. Squat Thrust: With your feet hip-width apart, bend your knees to place your hands on the ground and jump your feet back into a pushup position. Quickly reverse to return to standing.

3. Mountain Climber: From a pushup position, quickly bring alternating knees toward your chest.

4. Speed Skip: Skip in place, quickly bringing alternating knees up toward your chest.

Body Bonus: Sculpts your arms, back, shoulders, and legs
