Get into a side plank position with your legs and feet stacked, bottom hand under your shoulder, top hand reaching up toward the ceiling, inner thighs squeezed together, and abs engaged. Inhale to prepare. As you exhale, lift the hips higher and thread the top hand underneath the torso, rotating through the waist to complete one rep. Inhale to return to start position and repeat. Try 5-10 reps on one side before switching.
To regress this exercise, keep your knees on the ground.
