Stretching and mobility is essential in any strength training routine. It can help with full range of motion and preventing injury. Using a Lacrosse Ball can target those specific tight areas you need to work out. You can use it by pressing or rubbing the ball on one spot or laying on it.
This Lacrosse ball (or LAX ball) has firm enough to work out those tender spots but soft enough to use on your neck.
One of the most cost efficient mobility tools and easy to take with on the go.
