Dr. John Ball’s Pick: Pallof Press

Attach a resistance band to a wall or doorknob. Holding the band with both hands at belly button level, walk sideways away from the wall to create tension in the band.

(a) Stand perpendicular to the wall with your feet shoulder-width apart.

(b) Bracing your core, punch both your hands out in front of you and hold with arms straight while you count to three. Return to the starting position. Repeat 10 times.
