Dual-Function Strength Training

The Hoist HD-3900 combines two essential upper-body exercises into one efficient machine:

• Pec Fly for developing the chest muscles
• Rear Delt Fly for strengthening the rear shoulders and upper back

This dual-function design saves valuable floor space while giving users complete upper-body training versatility.

Superior Biomechanics

The HD-3900 is engineered to replicate natural body movement while minimizing unnecessary joint stress.

Each exercise arm features dual pivot points, allowing users to create a customized movement path that better matches individual shoulder mechanics. The result is smoother movement, greater comfort, and improved muscle engagement throughout every repetition.

Swiveling Handles with Rotating Grips

Unlike traditional pec fly machines, the HD-3900 includes swiveling exercise handles with rotating hand grips.

Benefits include:

• Multiple hand positions
• Reduced wrist strain
• Improved shoulder comfort
• Natural movement patterns
• Better exercise variety

These ergonomic handles help users maintain proper positioning throughout both Pec Fly and Rear Delt exercises.

Adjustable Range of Motion

The HD-3900 features 11 easy-to-adjust starting positions for each exercise arm, allowing users to customize their range of motion for optimal comfort and muscle activation.

This flexibility accommodates users with different shoulder mobility levels while supporting a wide variety of training styles.

Comfortable for Users of All Sizes

The machine includes seven seat height adjustments, making it easy for users of various heights to achieve proper alignment during every workout.

Proper positioning helps improve exercise effectiveness while promoting safer lifting mechanics.

Silent Steel® Weight Stack Technology

The Hoist HD-3900 utilizes HOIST's exclusive Silent Steel® Weight Rack System, which features precision-machined weight plates with durable nylon bushings.

Benefits include:

• Smooth operation
