Thoughts on this simple exercise pulley system for moving legs?

https://www.amazon.com/JH-Smith-Body-Exerciser/dp/B00266X5JY/ If you scroll down to the bottom of this product there is a short video showing how this simple pulley could possibly be used to move your legs. Thoughts? And if one didn't have strong arms, does anyone know how this could be adjusted to make pulling the legs easier? Also wondering if anyone knows of a similar product with something like velcro adjusted straps that might hold your feet better?

Did you end up making this work? It’d seem like the lack of knee stability would interfere.

No I never really figured out a pully for my legs but do use one with weight for my upper body, mainly for stretching. For my legs I use a motorized peddlar to get some movement. Here's a old video showing how it works https://youtu.be/nq2Mh1RCfTg
