The Best Abs Exercises: Walkout from Pushup Position
Why it works: This abs exercise involves full-body movement, such as using the arms and legs, while incorporating resistance to strengthen your entire core.
How to do it:
A. Start in pushup position with hands two inches wider than your shoulders.
B. Walk hands out as far as possible, then walk back. Do 10-12 reps.
Make it harder: Lift one leg before you walk your hands out and back.
