Ab-solutly effective ab wheel training tips:
Start with your weight equal between your knees and your hands. Tilt your pelvis back to clench your abs as much as you can.
Contract your glutes to push your hips forward and down so you shift your weight onto your hands.
Maintain tension in the abs and glutes as you flex your shoulders to roll your hands forward.
Pull back using your lats while keeping your hips and core locked.
