Psoas Muscle Self-Release With Ball
The Psoas muscle is usually tight and tender in most people. Jiu-Jitsu practitioners are no exception since we focus on keeping our hips up and in to prevent guard passing. Releasing this painful, tight, and tender muscle can be a challenge, but this technique is relaxing and easy to do. Not to mention that tight psoas muscles can be a contributor to low back pain, which is another common issue with BJJ players. Try this technique out, you will have looser hips and less pain.
