Will HandBand Pro® constantly move if you're doing an inconsistent movement like kipping pull ups?

I certainly understand your skepticism. If you haven't read my story, I've tried everything out there to protect my hands and offer a grip - specifically for kipping pull ups. They work. That's not to say there may not be a slight learning curve once you get them. They are very different from gloves and tape and everything else, so it may take you a few workouts to get them to feel like second nature to you - but most people get it right away!
