FAQ
What is the difference between the pec fly and rear delt functions on this machine?
The pec fly motion brings the arms together in front of the body to target the pectoral (chest) muscles, while the rear delt motion opens the arms outward behind the body to engage the posterior deltoids and upper back. The HD-3900 handles both movements on one machine, making it highly space-efficient for any gym floor.
What does the optional 5 lb. weight upgrade do?
The optional 5 lb. weight upgrade (part RS-CAGE-NG-OPT1) adds an additional 5 lbs. to the weight stack, bringing it from 310 lbs. to 315 lbs. More importantly, it allows for finer resistance increments, which is especially valuable for users who need precise, gradual progression in their training.
Is this machine appropriate for a commercial gym or hotel fitness center?
Absolutely. The HD-3900 is specifically designed and used by prestigious gym brands, hotels, and universities worldwide. Its patented Silent Steel® Weight Racks, durable construction, and intuitive adjustability make it ideal for high-traffic commercial environments where reliability and a premium user experience are essential.
How does the Silent Steel® Weight Rack feature work?
Silent Steel® is a patented HOIST technology that significantly reduces the noise and vibration typically generated when weight plates make contact during exercise. This creates a quieter, smoother lifting experience - a major advantage in settings like hotels, apartment gyms, or upscale fitness facilities where noise control matters.
