Yah, it looks gnarly but it feels great, it's your Pro-Tec Athletics RM Extreme contoured roller massager. Hit deep tissue adhesions, hotspots, and soreness with handheld pressure for control as you work things out. Wrap massaging nubs around body parts to release muscle tension from multiple angles. Dig in with a non-flexible design that generates all the leverage you need. Keep your body relaxed and injury-free with the RM Extreme, great before and after training or rest day maintenance.
