How to do a dumbbell swing:
- Stand with your legs shoulder-width apart and toes pointed slightly outward, holding the dumbbell (or a kettlebell, if you have it) in both hands.
- Swing the dumbbell backward between your legs, bending your knees slightly and pushing your hips back. Be careful not to round your spine.
- Forcefully squeeze your glutes, and drive your hips forward to thrust the weight forward and up as you straighten your legs. Aim to raise the weight to chest height.
- Allow the weight to fall between your legs, bending your knees and sitting your hips backward to begin the next rep.
