Bodymasters MD504 Pec Fly/ Rear Delt Combo. $2500

The Bodymasters MD504 Pec Fly/Rear Delt Combo is one of the most trusted and versatile upper-body machines ever built. Designed for commercial gyms, training studios, and serious home gyms, this dual-function unit delivers two essential movements in one compact footprint—a smooth pec fly for isolated chest development and a rear delt fly to target the upper back and posterior deltoids.

Built with Bodymasters’ legendary American-made construction, the MD504 features heavy-gauge steel, precision pulleys, and a durable weight stack system that provides consistent resistance through every rep. The adjustable seat and arms allow users of all sizes to dial in the perfect position for both chest and rear-delt movements, improving range of motion and muscle activation.

This machine is widely known for its biomechanics—engineered to follow the body’s natural movement pattern, reducing shoulder strain while maximizing muscle engagement. Whether your goal is chest isolation, shoulder balance, or rehab-friendly training, the MD504 remains one of the best combination machines ever produced.
