Attach suspension straps at mid-height; stand sideways to the anchor point and grip the handles with both hands, arms extended.
Brace your core and, keeping arms relatively straight, pull the handles diagonally across your body from high to low (or low to high) in a chopping motion.
Control the return to the starting position, resisting the pull of the straps.
Complete all reps on one side, then turn around and repeat on the other side.
