HMS LACROSSE BLC02 Massage Ball BLC02 HMS are double silicone Lacrosse balls used to release excessively tense myofascial points. The BLC02 HMS massage balls are very easy to use. Simply place them on a hard surface, such as a wall or floor, to stabilize their movement, then apply pressure to selected points on the body. Using massage balls allows us to reach even the most difficult-to-reach muscle groups. Their effectiveness stems from their small size, which allows for precise pressure on trigger points, the source of pain. BLC02 HMS balls are designed for athletes of all skill levels. They are excellent for minor pain in the neck, shoulders, backs, arms, and legs. They are often used by CROSS FIT athletes to improve mobility.
