Reps: 15
How to do it: Stand with your feet wider than hip-width apart, knees and toes slightly turned out, holding one end of a dumbbell with both hands.
Squat down and tap the dumbbell to the floor. As you stand, swing the dumbbell overhead, pressing your hips forward. Quickly lower back down into your squat.
Form tip: Get as low into your squat as you can, dropping your hips down and back. When you stand and swing the dumbbell, focus on squeezing your glutes together.
