Ab Circuit, Exercise 1: Walkout With Alternating Shoulder Tap
Start standing. Make sure your feet are hip-distance apart. Bend at your hips and reach down toward the floor with your legs as straight as they can be.
Keep your feet planted on the mat as you walk your hands forward until your shoulders are directly over your wrists and you're in a high plank position.
From the plank position, bring your right hand off the mat to touch your left shoulder without moving the rest of your body. With control, put your right hand back on the mat, tap your right shoulder with your left hand, and place your left hand back on the mat.
Slowly begin to walk your hands back to your feet, and come up to a standing position.
