Disclaimer: I am not a climber. However, I previously did CrossFit and pole fitness, and I am trying to get back into it. I appreciate good recovery tools, and I was browsing this page during a sale and decided to give this a shot. First I applaud the eco friendly packaging. Now, I’ll say I love these items. I’m 39 and everything hurts, so the roller ball has already been worth the cost of the kit. I use the black circular bands regularly, but I’m not 100% sure how to use the blue elastics. These are just like tourniquets I get in an IV start kit as a nurse, so I’m not sure if that’s their purpose or if they’re supposed to be used as resistance bands (maybe both?). The finger massager rings are fantastic. I haven’t needed to use the tape but after watching the videos on the Power Company website, I hope I find a reason to use it because it sounds like a very useful product.
