Stand facing the TRX straps and hold onto the handles with an overhand grip, keeping your arms straight and hands slightly wider than shoulder-width apart.
Keeping your core engaged, slowly raise your arms forward until they are overhead.
Pause for a moment at the top of the movement, then slowly lower your arms back to the starting position.
Start by setting up the TRX straps to a secure anchor point and adjust the straps so that they hang about waist height when you stand under them.
Stand facing the TRX straps, grab the handles with both hands, and step forward so that your body is in a plank position with your hands directly beneath your shoulders.
Lower your body down by bending your elbows until your chest nearly touches the handles. Keep your core tight and your body in a straight line.
Push your body back up to the starting position, straightening your arms as you do so. Make sure to engage your chest, triceps, and core throughout the movement.
