Taping your fingers is a great way to help prevent injuries during physical activity. It provides extra support and stability for the joints, helping them move more efficiently while also reducing the risk of sprains or strains. Additionally, taping can provide extra cushioning so that any impact on the hands isn't felt as strongly. This means you can train harder without worrying about getting injured. Furthermore, taping helps protect against friction from activities such as rock climbing which could cause blisters or skin irritation over time. Finally, if you already have an injury to one of your fingers, taping it up can give it additional protection and keep it immobilized until it has healed properly. All in all, taping your fingers is an easy way to reduce the risks associated with physical activity and make sure that you stay safe while having fun!
