Using the GoFit Go Roller is easy. For deep tissue therapy and self - massage, simply lie on the roller or place the affected body part on it and slowly roll back and forth. You can also use the trigger point ball to target specific areas. When doing upper body strength exercises, take advantage of the open design of the inner structure. As for maintenance, keep it clean by wiping it with a damp cloth. Avoid exposing it to sharp objects to prevent damage. Also, store it in a cool and dry place when not in use. Be careful not to over - pressure the roller, especially during the initial use, to prevent muscle soreness.
