A high quality pressure point tool designed to easily relieve muscle knots, muscle spasm and tightness that causes hip, knee and lower back pain. This size is recommended for athletes and active people who have a high tolerance to discomfort. Tight muscles will resist attempts to get them to relax. Targeted triggering which is similar to the pressure applied by a Massage Therapist or Chiropractor's knuckle or elbow, may cause increased local pain initially until the muscle starts to relax. This is to be expected and is a sign that you have located the a significant trigger point in the muscle. This product is also useful for improving posture in people who sit or stand for long periods. Its pointed triangle shape makes it more effective than a massage ball or lacrosse ball for targeting deep muscle tightness. It's flat stable base is designed to stop it rolling. Place against a wall or on a flat surface and use body weight to apply pressure. Recommended for release of Glutes, ITB, Quads. Piriformis, QL and Hip flexor muscles Also great for tension headache relief and improving mobility in the shoulder, neck and upper back.
