FAQ
How does the dual-function design work?
The DF-305 uses a direct drive system with two opposing cams - one for bicep curl and one for tricep extension. You can quickly switch between the two movements without changing cables or attachments, making it ideal for supersets and efficient programming in a busy facility.
Is the seat adjustable for different user heights?
Yes. Both the seat back and seat bottom are independently adjustable, allowing the machine to comfortably fit a wide range of users. This makes it especially well-suited for shared commercial environments where many different individuals will be using the equipment daily.
What is the minimum resistance available on each exercise?
The bicep curl starts at 11 lbs (5 kg) and the tricep extension starts at just 6.5 lbs (3 kg). These low starting weights make the machine accessible to rehabilitation clients, beginners, and lighter users, while the full 220 lb stack provides ample ceiling for advanced athletes.

Due to its size and weight (485 lbs), the DF-305 ships via freight on a pallet. Professional installation is recommended. Please contact us at service@omahasportsandgames.com for delivery scheduling and to confirm site access requirements before your order ships.
