This Trainer's 6-Move Ab Workout For a Stronger Core Takes Just 10 Minutes

• Begin in an elbow plank with your forearms resting on the top of the ball and your feet wide.
• Push your arms into the ball as you roll it away as far as you can without compromising your form (like breaking at the waist or over-arching your back).
• Slowly return to the starting plank position by contracting your abs and rolling the ball back toward your chest. That completes one rep.
• Do 12 reps.

Alternate move: kneeling ball rollout or standing ab rollout
