- Stand with your feet hip-width apart. Hold a dumbbell in each hand so your palms face in toward the sides of your body.
- Hinge slightly at the hips so your torso is at a 45-degree angle, and the dumbbells almost touching.
- Keeping a slight bend in the elbows, raise both hands up toward the ceiling so they're parallel with your shoulders. Keep your core tight and back flat as your lift the weights, not allowing your spine to curve or hunch.
- Slowly lower your hands back to your body to complete one rep.
- Keep going for 45 seconds, followed by a 15-second rest.
