Hey, I was just wondering if old grips can cause problems. I think my grips are about 12 years old. I just haven't wanted to spend the money on new ones but I'm thinking about it. They fall off my fingers and they've stretched out so much that they kind of curl up in my palm somewhat. I wasn't really concerned but I've been working on free hips and I've been getting bruises and now a huge painful lump on my palm near my thumb but I think right underneath the edge of where my grip would be. I'm not sure if the grips could be contributing to it or if its just because I'm not regripping the bar like I should. If anyone has any idea I'd appreciate the advice. Also if I get new grips what brand do you suggest is the best? I should probably get new ones anyway.
