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.
The move is a bit percussive, so focus on the rotation initiating in your torso.
Control the weight back up to the starting position to complete one rep.
Complete the same number of reps on each side.
Remember you are moving with force but also control. Don't give into the momentum of swinging the weight around.
