60 Seconds to a Slimmer Body

Reps: 20 seconds

Stand with feet hip width apart. Hold a dumbbell at both ends with both hands in front of the chest. Lower into a squat and lower a dumbbell to the side of the left thigh in a scooping motion (think of tracing a circle from the front to back). Stand up, raising the dumbbell back in front of the chest. Immediately repeat to the right.

Reps: 20 seconds

Stand with your feet together. Hold a dumbbell at both ends with both hands in front of chest. Quickly jump your feet apart and press the dumbbell overhead. Return to the start. Repeat as quickly as possible.

Reps: 30 seconds

Run in place, bringing your knees up high to your chest as your arms lift overhead and lower to your sides (as if doing a jumping jack). Repeat as quickly as possible.

Reps: 20 seconds

Begin in a lunge position with your right leg back and left arm extended overhead, your palm facing in. Jump up, switching your arms and legs midair, landing in a lunge with your left leg back and right arm overhead. Repeat as quickly as possible.

Reps: 10 seconds

Stand with your feet together and bend your knees. Lower into a squat, swinging your arms back by your hips. Jump up, opening your arms and legs midair into an "X" shape. Land in the starting position. Repeat as quickly as possible. (Too tough? Try a traditional jumping jack instead.)

Reps: 30 seconds

Stand with your feet hip width apart, holding the dumbbells at your sides. Lower into a deep squat, pressing the dumbbells into the floor under your shoulders. Keeping your arms extended and your shoulders over the dumbbells, jump your feet back to a full plank position with your feet together.

Jump back into the squat position, lift the weights, and pull your elbows behind your body, rowing the weights to the sides of your torso while keeping your back naturally straight. Return to the start and repeat.
