3 Moves That Will Tone Your Body and Give You More Energy

WORKS: shoulders, abs and legs. Stand with feet together and arms at sides, knees bent (A). Pulse three times and then jump up, reaching arms and legs out into an "X" shape (B). Land gently with feet together, knees bent and arms by sides. Repeat for 20 seconds. Rest 10 seconds; repeat eight times.

MAKE IT EASIER: Do regular jumping jacks instead.

MAKE IT HARDER: Skip the pulses and do continuous Star Jumps.

WORKS: arms, back, abs and butt. Start in plank position with shoulders above wrists and legs extended (A). Keeping shoulders still, jump diagonally to left, tucking knees into left elbow (B). Jump feet back to plank; repeat tuck to right. Alternate sides for 20 seconds. Rest 10 seconds and repeat eight times.

MAKE IT EASIER: Pull knees to center and jump feet straight back to plank.

MAKE IT HARDER: Go faster.

WORKS: abs, butt, thighs and hamstrings. Stand with feet together and hands on hips. Hop right foot forward into a deep lunge, left knee almost to ground (A). Quickly spring back to standing, feet together (B). Do for 20 seconds with 10 seconds of rest. Repeat on opposite side. Continue for 4 minutes.

MAKE IT EASIER: Step-lunge forward instead of hopping.

MAKE IT HARDER: Bring arms overhead as you lunge.
