Tone and Tighten With a 30-Minute Strength Program

Alternating overhead squat

(for legs, core, shoulders)
Stand with feet shoulder-width apart, toes slightly turned out, and hold a dumbbell in each hand. Keeping your spine lengthened and core engaged, squat down, pressing hips back. At the same time, press a dumbbell overhead and reach the other toward the floor. Return to starting position. Repeat squat with opposite arm; that’s 1 rep. Do 2–3 sets of 8–15 reps.
