To add more versatility to your Pilates reformer and workout, invest in the AeroPilates Pull-Up Bar. Strengthen and sculpt your upper body by targeting the back, shoulders, biceps and triceps with the same machine that also engages your core, lower body and builds cardiovascular endurance. Use one, two, three or four cords to make the pull-ups easier or more difficult. Attaching the AeroPilates Pull-Up Bar is just as easy as our other AeroPilates accessories. Simply loosen the locking knobs to remove the pulley risers, insert the bar attachment and re-tighten the locking knobs.
