Chirp - RPM Mini - Black

The Chirp RPM mini combines two excellent relief and recovery methods, percussion and rolling massage like the original RPM, but in a mini travel-size version! The alternating percussive bar design creates a percussive effect to mobilize muscle knots and promote blood circulation to the area. The rolling massage stretches the muscles over a larger area for a deeper, more effective stretch.
