Rotation movements, like the high-to-low woodchop , engage your core by forcing it to resist the side-to-side motion, said Rachel McPherson, ACE-certified personal trainer. "This helps strengthen and stiffen the side body and core." Keep this move steady and controlled, resisting the momentum of swinging the weight around.
- With feet slightly wider than hip distance apart, twist upward to the right, bringing the dumbbell above your head.
- Exhale and slice the weight diagonally across your body, ending twisted to the left with the dumbbell outside your left thigh. Pivot on your right foot as needed and focus on the rotation initiating in your torso.
- Control the weight back up to the starting position to complete one rep.
