Accessible Butterfly + Standard Reverse Butterfly (Config. A) This setup enables inclusive upper body training by pairing an Accessible Butterfly station with a Standard Reverse Butterfly. The patented design (U.S. Patent 9,079,069) allows users in wheelchairs to perform pressing movements without transferring, building strength in the chest, shoulders, and triceps. The opposite side features a standard reverse fly station for back and rear shoulder development, allowing two users - one seated, one standing - to work out simultaneously and independently.
