With the Open steadily approaching hand care and preventing rips are a big concern.. Here is a short and sweet video showing how to make a wrap to protect your hands in just a few min using some athletic tape. A great simple and relatively cheap option, these can be reused a few times just be careful when taking them off.
If you are looking for a more permanent option that is a little more expensive check out these: LINK HERE they have great reviews, I have not used them first hand ,:) but sources tell me they are very effective. I personally would go with the purpose built product and not tape. The durability and convenience will more than pay for itself (tape isnt cheap either) with a few uses. But if you are in a pinch and can steal/borrow some tape from someone the video above is easy and fast to follow. Go forth and do pullups without leaving flesh behind!
