Place the ball on the floor or against the wall and apply pressure to the desired muscle. Roll the ball in up and down, side to side, or in circular motions to experience relief.

Anytime! You can use the MojiHeat massage balls whenever your muscles feel tight, stiff, sore, and need some relief. The MojiHeat massage tools are great for warm-up and recovery rolling sessions.
