Place TRX straps at waist height.Stand facing TRX with feet a little wider than hip-width apart.Hold both handles, making a fist around the handles. Take a few steps back, and lean away from the straps so that arms are fully extended, core engaged. Keeping arms straight, pull yourself toward the straps, driving hands to the right. Return to starting position, then repeat, this time driving hands to the left.That’s 1 rep.Repeat for 10 to 12 reps.Make it easier or harder: Walk feet away from the straps (so your body is at less of an angle) for less of a challenge. Or for more of a challenge, walk feet toward the straps (so your body is at more of an angle).
