SportsArt DF-300 Leg Extension / Leg Curl Machine
Description
The SportsArt DF-300 is a dual-function selectorized strength machine that combines leg extension and seated leg curl into a single, space-saving unit. Designed for commercial gyms, fitness centers, and performance training facilities, it delivers two of the most essential lower-body movements in one beautifully engineered frame. The direct drive system features two opposing cams, eliminating cable slop and ensuring smooth, consistent resistance throughout every rep. Transitioning from quadriceps training to hamstring work is fast and intuitive, keeping workouts moving without downtime. Adjustable seat back and leg pads make it easy to fit users of all sizes, while the 220 lb weight stack provides plenty of resistance for serious athletes. If you need to maximize floor space without sacrificing training quality, the DF-300 is the smart choice.

FAQ
How does the dual-function design work?
The DF-300 uses a direct drive system with two opposing cams to enable both leg extension and seated leg curl movements on the same machine. The user simply adjusts their position and the leg pad configuration to switch between targeting the quadriceps (extension) and the hamstrings (curl). The transition is designed to be quick and intuitive, minimizing downtime between exercises.
Is this machine suitable for rehabilitation use?
Yes. The low starting weight of just 13 lbs on both the curl and extension motions, combined with the fine 5 kg plate increments and fully adjustable seat and leg pads, makes the DF-300 well-suited for rehabilitation settings. It allows therapists and trainers to begin with very light, controlled resistance and progress gradually as the user recovers strength.
How will this machine be delivered?
Due to its size and weight - nearly 500 lbs - the DF-300 ships via freight on a pallet. Professional delivery and installation are recommended. Please email us at service@omahasportsandgames.com before ordering if you need details about your specific delivery location or lead times.
What is the maximum user weight capacity?
The DF-300 is rated for a maximum user weight of 500 lbs (227.3 kg), making it appropriate for a wide range of users in commercial and institutional fitness environments.
Does the DF-300 require assembly?
Yes, some assembly and setup is typically required for commercial selectorized machines of this size. Professional installation is recommended to ensure the machine is set up safely and correctly. Contact us at service@omahasportsandgames.com for more information or to arrange installation support.
