OMG 658 Posted January 19 Anyone else using one so something similar? Great wrist forearm workout, I use it while driving. I've been wondering what physics causes them to spin up. Quote Share this post Link to post Share on other sites

RichardCranium 1,184 Posted February 3 Not sure what a dyna flex is. Your post is pretty light on info. I have a forearm exerciser/flexer thingie that I don't remember what its called. I used it after the bike crash where I had to have my hand pinned back together for a few weeks. Quote Share this post Link to post Share on other sites
