FAQ
What exercises can I perform on the HD-3900?
The HD-3900 is designed as a dual-function machine that targets two key upper body muscle groups. The pec fly exercise works the chest (pectorals), while the rear delt movement targets the posterior deltoids and upper back. The swiveling handles and dual-pivot arms allow for a natural range of motion on both movements.
Can users of different heights use this machine comfortably?
Yes. The HD-3900 features seven seat pad adjustment positions, making it easy for users of varying heights to find a safe and ergonomic position for both the pec fly and rear delt exercises. The 11 range-of-motion adjustment positions further personalize the experience for each individual user.
What is the Silent Steel Weight Rack feature?
Silent Steel is HOIST's patented weight stack guide system that significantly reduces the noise typically produced when weight plates contact each other during use. This makes the HD-3900 an excellent choice for upscale or noise-sensitive environments like hotel fitness centers, corporate gyms, and university facilities.
Is the optional 5 lb. weight upgrade worth it?
For facilities serving a wide range of users - from beginners to advanced athletes - the optional 5 lb. weight upgrade (RS-CAGE-NG-OPT1) adds finer resistance increments between standard weight settings. This can be especially beneficial for rehabilitation programs or users who want smaller progressive overload steps. The total stack increases from 310 lbs to 315 lbs with the upgrade.
How is this machine delivered and does it require assembly?
Due to its size and weight (649 lbs), the HD-3900 ships via freight on a pallet. Professional installation is strongly recommended. Please email us at service@omahasportsandgames.com for delivery scheduling and to confirm any site access requirements before your order ships.
