1, the action principle is different. The foam shaft combs the muscles and reduces the tension by rolling itself and concentrating its weight. The area for single relaxation is larger. For beginners, it is recommended to use foam shaft (fascia ball) to relax, so it is easier to feel muscle tension.

2. The relaxation effect is different. Because of their different working principles, it is generally recommended to use a fast-frequency fascia gun before training and then use a foam shaft for proper traction after training.

Both the massage ball and the foam shaft roll repeatedly on the muscles that need to be relaxed by their own weight, while the fascia gun relaxes the muscles and soft tissues by high-frequency impact on the target parts of the body.

Both the foam shaft and the massage ball may be stuck.
