The Volksgym Butterfly S5-4 is a dedicated pec deck machine that targets the chest through a controlled fly movement — the exercise that builds the inner chest line and stretch that flat bench pressing alone cannot deliver. With an 82 Kg selectorized weight stack and Volksgym's mid-range S5 professional frame, the S5-4 gives personal training studios and serious home gyms a purpose-built chest isolation station at a fraction of what commercial pec deck machines cost.

The Butterfly S5-4 pairs naturally with the Volksgym Chest Press S5-3 for a complete pressing-plus-isolation chest training station. Here's how they complement each other:

Who Should Buy the Volksgym Butterfly S5-4

• Bodybuilders and physique competitors in the UAE who need the deep chest stretch and peak contraction that only a pec deck delivers — the fly movement develops the inner chest separation that pressing movements miss
• Personal training studios adding a dedicated chest isolation station alongside their press machine — clients see and feel the difference when pec deck flies are part of their chest program
• Home gym owners who already have a bench press and want to add the isolation component — the butterfly is the single most effective machine for developing chest definition beyond what compound pressing provides
• Rehabilitation and older fitness enthusiasts — the controlled arc of motion is safer on the shoulder joint than dumbbell flies, making it suitable for users returning from shoulder injuries under professional guidance

Frequently Asked Questions

What muscles does the butterfly machine work?

The primary target is the pectoralis major (chest), with emphasis on the inner (sternal) fibers during the squeeze phase. Secondary muscles include the anterior deltoid (front shoulder) and serratus anterior. Unlike the chest press, the butterfly isolates the chest without significant triceps involvement.

Is the butterfly better than dumbbell flies?

Each has advantages. The butterfly machine maintains constant tension throughout the entire range of motion — dumbbells lose tension at the top. The machine also eliminates the stabilization requirement, allowing you to focus purely on the chest contraction. Dumbbell flies offer a deeper stretch at the bottom. For maximum chest development, use both: the S5-4 for peak contraction training and dumbbells for deep-stretch work.

Can I do reverse flies for rear delts on this machine?

The S5-4 is a dedicated pec deck — the arm pads face inward for chest flies. For rear delt reverse flies, look at the Volksgym cable crossover stations which allow face-pulls and reverse fly movements with adjustable pulleys.

How does the 82 Kg stack compare to other brands?

Most commercial pec deck machines carry 70–90 Kg stacks. At 82 Kg, the S5-4 sits in the upper range. Since pec deck flies are an isolation exercise, most users train in the 20–50 Kg range — the full 82 Kg stack provides ample room for progressive overload.
