Combines the best of the Body Back Buddy features for those who want the ultimate self massage tool. Overall length is 25 . Comes with a free 12 page instruction booklet. Directions: Hook the Body Back Buddy massage tool over your shoulder or around your side to treat hard to reach areas of the back, neck and shoulders. Hold it comfortably by the handles or the frame so that the therapy knob touches the affected muscle. Push away from your body with your lower or outside hand while guiding the therapy knob with the upper or inside hand. This leveraging technique creates self-directed pressure to the targeted muscle. You can also use the Body Back Buddy to apply healing pressure to many other parts of the body such as your legs, arms, feet, chest and hips. Its versatility allows you to approach each muscle from many angles in creative ways. Since there are hundreds of ways to use the Body Back Buddy, take a moment to experiment and find out what works best for you. Use it standing, sitting, lying down or with a partner. Place the therapy knob on the sore muscle (trigger point) and apply what you consider to be a comfortable amount of pressure. When this muscle compression is released it stimulates a therapeutic response. Pressure preferences vary from one person to another deep and intense or gentle and relaxing. However, only apply as much pressure as you feel comfortable with. More pressure is not necessarily better! Ten to thirty seconds is normally enough time to elicit a therapeutic response in the muscle.
