Two Machines in One – Complete Chest and Shoulder Isolation
Isolation exercises are essential for complete muscle development—compound movements build mass, but isolation movements create the detail and definition that distinguish developed physiques. The Spartaks Strength Pec Fly and Rear Delt Machine provides two critical isolation exercises in one compact unit, allowing you to target the chest with fly movements and the rear delts with reverse fly movements without needing separate machines.
The controlled movement path is the key advantage over free-weight alternatives. Dumbbell flyes and reverse flyes require significant stabilization and can stress the shoulder joint at end ranges of motion. This machine guides the movement through a fixed arc, ensuring proper form and consistent resistance throughout each repetition. The result is targeted muscle stimulation with reduced injury risk—ideal for bodybuilders seeking detail work, athletes requiring shoulder stability, and anyone rehabilitating from injury. For facilities where space and equipment efficiency matter, this dual-function design delivers exceptional value by combining two essential exercises in one footprint.

Muscles Targeted – Complete Upper-Body Isolation
The dual-function design targets two distinct muscle groups that are often underdeveloped yet critical for complete upper-body aesthetics and function.
Pectoralis Major (Pec Fly)
The primary chest muscle responsible for chest width and definition. The fly movement isolates the pectorals without the tricep involvement of pressing exercises, allowing focused chest development. The controlled arc provides a deep stretch at the start and strong contraction at the finish, creating the muscle stimulation needed for chest detail and separation.
Pectoralis Minor (Pec Fly)
The smaller chest muscle beneath the pectoralis major. While often overlooked, developing this muscle contributes to full chest development. The fly movement engages the pectoralis minor throughout the range of motion, supporting complete chest development.
Posterior Deltoids (Rear Delt Fly)
The rear shoulder muscles are often the most underdeveloped of the three deltoid heads. The reverse fly specifically targets this area, building the three-dimensional shoulder appearance that completes a developed physique. Strong rear delts also support shoulder health and improve posture.
Rhomboids & Mid-Traps (Rear Delt Fly)
The upper back muscles work synergistically with rear delts during the reverse fly motion. Building these muscles contributes to upper back thickness and postural support. Many people with forward-head posture benefit from strengthening these muscles.
Infraspinatus & Teres Minor (Rear Delt Fly)
These rotator cuff muscles assist during the reverse fly motion. Strengthening these muscles supports shoulder stability and can help prevent injuries. The controlled movement path provides safe, effective strengthening for these important stabilizers.

Exercise Execution – Pec Fly vs. Rear Delt Fly
Understanding proper execution of both exercises maximizes the machine's value and ensures optimal results.
Pec Fly (Chest Fly)
Position: Sit facing the machine with back against the pad. Grasp the handles or place forearms against the pads with arms slightly bent.
Movement: Bring arms together in an arc motion in front of your chest, squeezing the pectorals at the peak contraction. Control the return to the starting position, feeling a stretch across the chest.
Key Points: Maintain slight elbow bend throughout—do not bend and straighten during the movement. Focus on squeezing the chest muscles rather than pushing with the arms.
Rear Delt Fly (Reverse Fly)
Position: Sit facing the pad (opposite direction from pec fly) with chest against the support. Grasp the handles with arms in front of you.
Movement: Pull arms back in an arc motion, squeezing the rear delts and upper back at the peak contraction. Control the return to the starting position.
Key Points: Focus on pulling with the rear delts, not the arms. Keep chest against the pad to prevent using momentum. Visualize squeezing your shoulder blades together.
Key Training Benefits
The Spartaks Strength Pec Fly and Rear Delt Machine delivers benefits that make it essential for complete upper-body development.
Chest Definition and Detail
The pec fly isolates the pectorals without the tricep involvement of pressing exercises. This isolation creates the chest detail, separation, and definition that pressing alone cannot achieve. Bodybuilders use fly movements specifically to create the striated chest appearance that distinguishes developed physiques.
Complete Shoulder Development
The rear delt fly targets the most commonly underdeveloped shoulder area. While front and side delts get plenty of work from pressing movements, rear delts require targeted training. Building rear delts creates the three-dimensional shoulder appearance and contributes to the complete upper-body aesthetic.
Posture Improvement
Strengthening the rear delts and upper back directly counteracts the forward-shoulder posture common in modern life. Desk workers, drivers, and anyone with forward-head posture benefit enormously from rear delt training. Improved posture reduces pain and creates a more confident, athletic appearance.
Shoulder Joint Health
Balanced development between chest and upper back supports shoulder joint health. Many shoulder issues result from strength imbalances between the front and back of the shoulder girdle. Training both pecs and rear delts helps maintain this balance, potentially reducing injury risk.
Safe Training Environment
The controlled movement path creates a safe training environment for all experience levels. Beginners learn proper mechanics without coordination challenges, while advanced trainees can push to failure safely. The guided motion is also ideal for rehabilitation settings.

Frequently Asked Questions About the Pec Fly and Rear Delt Machine
What muscles does the pec fly work?
The pec fly primarily targets the pectoralis major—the main chest muscle responsible for chest width and definition. The pectoralis minor, located beneath the major, also receives stimulation. The movement isolates the chest without the tricep involvement of pressing exercises, allowing focused chest development. The anterior deltoids assist slightly during the movement.
What muscles does the rear delt fly work?
The rear delt fly primarily targets the posterior deltoids—the rear head of the shoulder muscle. It also engages the rhomboids, middle trapezius, and the rotator cuff muscles (infraspinatus and teres minor). This combination makes it excellent for upper back development, posture improvement, and shoulder joint health. The rear delts are often underdeveloped, making this exercise particularly valuable.
Is this machine better than dumbbell flyes?
Both have their place. Machine flyes offer controlled motion that's easier on the shoulder joint, especially at end ranges of motion. They also allow training to failure without coordination challenges. Dumbbell flyes provide more freedom of movement and may feel more natural to some trainees. Many lifters use both—machines for safe isolation and controlled training, dumbbells for variety and different stimulus.
How do I switch between pec fly and rear delt?
The machine design allows easy switching between exercises. For pec fly, you sit facing the machine with your back against the pad. For rear delt fly, you turn around and face the opposite direction with your chest against the pad. The same movement arms work for both exercises—you simply reverse your position. This quick transition makes supersets between chest and rear delt exercises easy.
Is this machine suitable for beginners?
Absolutely. The guided motion path makes both exercises safe and accessible for beginners. The fixed arc ensures proper form without the coordination challenges of free weights. Beginners can focus on feeling the target muscles work rather than managing dumbbells. The controlled movement is also safer for those learning their strength limits.
Will this help my posture?
Yes, particularly the rear delt fly function. Many people develop forward-shoulder posture from desk work, driving, and other daily activities. Strengthening the rear delts and upper back muscles helps pull the shoulders back into proper alignment. Regular rear delt training, combined with stretching the chest, can significantly improve posture over time.
