5" Orb working like a charm to take away adhesions. Better at pinpointing where pressure should go than a roller of the same size - really gets between muscles to separate adhesions. A bit of give like a foam roller so more massage or pressure feel as compared to the bite of a lacrosse ball. Also easier to maneuver into specific spots and drive the pressure with bodyweight than a lacrosse ball because the bigger size gets my leg further off the floor when rolling quads and hamstrings. Also exceptionally good at hitting the front of hips / psoas for release because of the size. Highly recommended!
