A foam roll is a useful tool for sore muscles, especially if you don't have anyone else around to help you. This long piece of foam can be used to roll across a muscle, elongating the muscle tissue and breaking up any scar tissue or other issues that may have begun to accumulate. This is essentially a quick and cheap way to give yourself a deep-tissue massage without the help of anyone else, so it's recommended for those who might be in a hurry or who need a bit of regular soreness relief. Foam rollers are rarely expensive, so think about adding one to your workout collection.Next
