Feature Highlights

• Dual-Function Upper-Body Training: This machine combines pec fly and rear delt movements in one station, allowing facilities to train chest, posterior shoulder, and upper-back muscles without dedicating floor space to two separate machines. Users can move efficiently between pushing and pulling isolation patterns for balanced upper-body development.
• Selectorized Resistance System: The single 200 lb weight stack allows users to change resistance quickly with a weight selection pin. This makes the machine easy to use in commercial gyms, personal training studios, and multi-user fitness spaces where fast setup and repeatable resistance settings matter.
• Smooth Cable and Pulley Motion: High-grade pulleys, cables, and self-lubricated bushings help deliver consistent resistance through the movement path. The result is controlled muscle engagement for chest flys, reverse flys, rear delt raises, and shoulder isolation work.
• Adjustable Ergonomic Positioning: The adjustable seat, backrest, and training position help users align their body for better biomechanics. Proper positioning supports comfort, helps isolate the intended muscles, and accommodates a wider range of users in busy training environments.
• Commercial-Grade Durability: A solid steel frame, durable upholstery, and robust moving components make this pec fly rear delt machine suitable for frequent use. It is built for commercial gyms, athletic facilities, performance centers, and dedicated home gyms that need reliable selectorized strength equipment.
