Constantly shifting your weight and balance as you slide the towel forward strengthens the entire arm, as well as the postural muscles and core, big time, Speir explained.

1. Come into a plank position and place the hand towel under the left hand.
2. Keeping both arms straight, press your left hand forward. Don't go past the point of control — the point where the body can remain in a straight line with the abs engaged.
3. Draw the arm back in to the starting position to complete one rep.
4. Complete 30 seconds on each side.
