Will the fascia gun hit the muscles

No, it just relaxes the muscles.

From a scientific point of view, this product can be regarded as one of the massage tools, rather than having special medical effects. If the user is not sure about the basis or guidelines for using the fascia gun, he may use too much massage or press for too long. Generally speaking, slow massage or vibration can achieve the effect of relaxing the muscles. Since muscle size and age will affect the required strength, it is recommended that consumers choose models with adjustable strength.
