The plan: Do each move for 1 minute. Knock out as many reps as you can, then immediately start the next move. Feel strong? Go again!
Tones: Butt, thighs, shoulders, triceps, and core
Stand with your feet hip-width apart. Hold dumbbells up at your shoulders—elbows bent and pointing out to the sides, palms facing forward. Take a giant step forward with your right leg and lower your body until your knees are bent 90 degrees. Your knees should be in line with your ankles. (A) Press into your right foot, straighten your right leg, and come to a stand, simultaneously pulling your left knee forward in front of your hips (so you’re standing on one leg) and pressing the weights up toward the ceiling .(B) Return to start. Repeat with your left leg. 10 to 12 reps per leg
Assume a side plank position, with your right elbow on the floor directly beneath your shoulder. Stagger your feet so your left foot is in front of your right foot. (A) Raise your left arm directly overhead—bicep next to your ear, arm extended, and with your palm facing the floor—so your arm is in line with your body. Arch your left arm towards the floor as you raise your hips up in the air. (B) Return to start. Repeat for a full set; then switch sides. 8 to 10 reps
