Lay rope long and horizontally on floor. Start facing center of rope on floor on all fours with left hand holding left rope handle and right hand on floor on top of center of rope. Pull bent left arm up (palm faces backward) until fist reaches chest height; pull bent right leg toward chest.
Without touching floor, extend left arm forward at shoulder height and right leg backward and slightly up. That's 1 rep. Do 24 reps. Switch sides; repeat. That's 1 set. Do 3 sets.
