Want to Try the Ab Wheel? These 4 Moves Will Challenge Your Balance and Ignite Your Core

After conquering the first two exercises, Eric and Ryan recommended this elevated plank march on the ab wheel to get your lower body involved as well. It's challenging for both your abs and your balance.

• Get into a high plank position with both hands on the ab wheel and your arms directly below your shoulders.
• Lift your left leg slowly, keeping your foot flexed and core engaged so your back doesn't sag.
• Set your left leg back down, and repeat with your right leg.
• This completes one rep.
