The Bumpy firm-density roller has alternating rows of firm finger-size bumps that mimic a kneading massage style. It is ideal for relieving tight muscles, performing myofascial release, and providing a stimulating deep tissue massage. The bump pattern stretches muscles in multiple directions simultaneously. This targets tightness, knots, and trigger points to improve flexibility, mobility, and range of motion. Most often used between workouts when muscles are tight and stiff.
