This foam roller is not for the faint of heart, nor is it for those who don't enjoy some pain during their recovery sessions. However, for all the pain it deals out, it does some miraculous work releasing tension in hard to fix knots. It comes in various sizes and an option for extra firm (for the masochists). We like the compact version because it can fit in a bag and wont break the bank.
