We love the woodchop since it works your upper and lower abs while standing.
- Holding an four- to 5-kilogram 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. Complete the same number of reps on each side.
