Roll away muscle pain in minutes. Unlike traditional smooth foam rollers, this one has been designed in Germany with a multi-dimensional textured surface to penetrate deep into muscle fibres, targeting trigger points and loosening stubborn knots, and stimulating blood and oxygen flow to sore muscles for faster recovery. It's your portable, personal physical therapist! Whether you need to pamper your tight, aching shoulders or you want to finally bust that annoying knot in your lower back, this roller has you covered.
