We love the wood chop, and this variation is one of celeb trainer Gunnar Peterson's favorites.
- Holding an eight- to 10-pound dumbbell overhead, twist to the left, pivoting your right foot as needed.
- Exhale, and slice the dumbbell across your body to the right as you raise your right knee, bringing the weight to the outside of your right hip.
- Raise the weight back to starting position, and lightly tap your right toes to the floor. This completes one rep. Do three sets of 15 reps on each side.
