Set of massage balls in 3 different hardnesses for acupressure massage and trigger point release. Starting with the softest (least aggressive) ball choose a ball of suitable hardness and position it on the point to be massaged. For the lower back or glutes start in a sitting position; for calfs or thighs try either sitting or lying on the floor and gently roll around on the ball. For shoulders and upper back place the ball between your back and a wall. For the neck, roll the ball around between your neck and open palm. Use in conjunction with a foam roller for great results!
