A foam roller is a must-have recovery tool for any woman who practices calisthenics. This cylindrical foam tube is used for self-myofascial release, which helps relieve muscle tension, improve flexibility, and reduce post-workout soreness. It's a versatile tool that can be used to target different muscle groups, including the back, legs, and arms. Look for a foam roller with a textured surface for deeper massage and better blood circulation. It should be firm enough to provide effective pressure but not too hard to cause discomfort. With a foam roller, she can give herself a relaxing massage after intense calisthenics sessions, promoting faster recovery and preventing injuries.
