We can see many such foam shafts in the gym, which is a good tool for relaxing muscles in the gym, so that your muscles can be relaxed and relieved to a certain extent, and the muscle pain caused by training tension and fascia adhesion can improve the poor flexibility caused by insufficient joint activity. This kind of foam shaft can be used before and after training. I suggest you relax your lower back with a foam shaft.

Why use a foam shaft to relax the lower back? When we use the foam shaft, these bones will help you support your body, so we can see intuitively that the stress on the muscles of the lower back of a big fish is far greater than that on the upper back. Such a big pressure itself may be more vulnerable. But the main purpose of using foam shaft is to relax, but when you put too much pressure on your muscles, it will cause muscle tension and confrontation.

Everyone feels differently. It's not normal to stay nervous all over after several times, so we can't relax. So we use foam shaft to relax the lower back, which is likely to lead to more serious pain. In this case, it is really a bad thing for our lower back, especially for our lumbar spine.

Therefore, it is suggested that the majority of fitness friends, no matter how many people are using the foam shaft to relax their backs, you'd better not do this back relaxation, but it doesn't mean that the foam shaft has no other functions. We can relax the gluteus medius and rectus femoris with foam shaft, and piriformis is also a very good choice.
