RUMBLEROLLER - Beastie Bar XFirm
The Beastie Bar contains two Beasties permanently mounted, but free to rotate, on a rigid fibreglass shaft. Both the Beastie and Beastie Bar have the same effect on muscle. Choose the Beastie for ultimate portability and to work into the smallest areas of your body. Choose the Beastie Bar if you prefer its 2-hand control.
Xfirm (green): extremely firm, similar to a lacrosse ball.
