Frequently Asked Questions

What is a variable resistance cam?

The cam shape changes leverage through the movement — heavier at mid-range where quads are strongest, lighter at end ranges to protect the knee joint.

Can this be used after knee surgery?

Yes, the ROM limiter allows precise range-of-motion settings for post-operative rehabilitation. Always consult your physical therapist first.

What is the starting weight?

The first plate is approximately 10 lb. With the 5 lb add-on, you can work as low as 15 lb for rehab protocols.

Can I do both leg extensions and curls on one machine?

Some models are dual-function. However, dedicated machines each provide superior biomechanics and are the standard for commercial gyms.

Is this machine safe after knee surgery?

The adjustable ROM limiter makes this excellent for post-surgery rehab under professional supervision. Follow your physical therapist's protocols.
