The Pulseroll Vibrating Foam Roller is the perfect training aid for both pre and post training sessions or races. It features vibrating technology that helps to improve general muscle health and recovery time by increasing blood flow and oxygen to your muscles. When used before a ride or turbo session, run or swim, it can enhance performance, and when used after, it can help speed up recovery and reduce delayed onset muscle soreness (DOMS), meaning you can get back to your next session sooner! The low power settings are ideal for a more relaxing massage, either on tired or sensitive areas, and the higher levels deliver a more intense deep tissue treatment for knots and trigger points. A handy thumb remote-control ensures ease of use, and is unique to Pulseroll.
