BLM02 HMS are double balls designed to relieve highly tense myofascial trigger points. The BLM02 HMS massage balls are very easy to use. Simply place the ball on a hard surface like a wall or floor to stabilize its movement. Next, you need to apply pressure to the selected body points. By using balls for massage, you can also reach the least accessible muscle areas. Their effectiveness is based on their small size, which allows you to target trigger points, or the source of pain, precisely. The BLM02 HMS balls are intended for athletes of varying performance levels. They are excellent for alleviating mild neck, shoulder, back, arm, and leg pain. They are often used by people who do CrossFit to improve motor mobility.
