This machine is designed primarily for light commercial environments such as hotel gyms, corporate fitness facilities, and hospitality fitness rooms. At 484 lb overall weight and with a 190 lb weight stack, it is a heavy-duty piece of equipment. While technically usable in a home setting with adequate space and flooring, it is best suited for commercial or semi-commercial facilities.
What exercises can I perform on this machine?
This dual-function machine supports two exercises: the seated leg extension (targeting the quadriceps) and the seated leg curl (targeting the hamstrings). Both exercises are performed on the same unit with smooth transitions between them, eliminating the need for two separate machines.
How does the Lock N Load® weight selection system work?
Lock N Load® is Nautilus's patented weight selection system. It allows users to quickly and securely select their desired weight on the stack with a simple, positive-locking pin mechanism. It is designed to be faster and more reliable than traditional weight pin systems, reducing the chance of the pin slipping or being improperly inserted.
Does this machine ship assembled?
This machine ships via freight on a pallet due to its significant weight (553 lb shipping weight). Some assembly and professional installation is recommended upon delivery. Please contact us at service@omahasportsandgames.com to confirm shipping details and get a delivery quote before purchasing.
Can the range of motion be adjusted for different users?
Yes. The machine features dual exercise option range of motion control for both the leg extension and seated leg curl functions. This allows facility staff or individual users to set appropriate movement limits based on comfort, injury history, or training goals.
