The Charge Vibe is probably one of the best ways to improve thoracic kyphosis, rounded shoulders and release muscle knots in the back and shoulders. This is a quick video on how to use the Vibe. Careful! Less is more. Start with just resting on the Vibe with the head supported. Progress to the other techniques as you get better. Do this 2-3 times a week for just a few minutes at a time to see improvement.
