B Strong Training System - Standard Arms and Legs

I am using it to speed up my recovery from surgery to repair my torn achilles. It is working well. It is easy to use and well made. I am glad that I bought it.

Am dubious however about long-term effects of lubricant cooking oil on the o-ring of the valve, maybe design can be improved

I’ve used them before, I just wrote out the last set. My new product is even better than years ago, glad to be using them, best way to biohack your way back!!
