Pec deck fly – Rear deltoid

The Pec Deck Fly – Rear Deltoid Machine is designed to target both the chest (pectoralis major) and rear shoulder (posterior deltoid) muscles through controlled forward and backward arm movements. The guided motion ensures proper shoulder alignment, reduces joint strain, and provides smooth, consistent resistance. This machine is ideal for building chest and rear deltoid strength, improving upper-body stability, and supporting balanced muscle development for users of all levels.
