The first adaptive massage roller is here! This first-ever, transforming Revolve Roller® massager from GoFit® adapts for targeted massage. You adapt it to fit your massage needs by rearranging the 9 included adaptive massage rings. These interchangeable rings provide ultra-diverse massage options, from superficial to deep tissue compression. Each ring has variable patterns of raised ridges that promote circulation and release trigger points. Simply slide the rings on and off the roller to create limitless massage configurations! * Before beginning any weight loss or exercise program, you should consult with your physician.
