The Machine Pec Deck Fly targets the chest (pecs) and front shoulders for precise muscle activation. Sit on the pec deck machine with your back against the pad and feet flat on the floor. Grip the handles, elbows slightly bent, and bring your arms together in front of your chest in a controlled arc. Slowly return to the starting position, keeping tension on your chest (pecs) throughout the movement. Gymcheq ensures correct posture and form to maximize chest (pecs) engagement while minimizing shoulder strain.
