Instrument Assisted Soft Tissue Mobilization, is a myofascial release (massage) methodology developed by one of the largest and strongest men in the world - Donnie Thompson. Besides being a famous powerlifter and the first human to lift 3,000 pounds total in the squat, bench press, and deadlift, Donnie is also a world-renowned rehab specialist sought-after by countless athletes in different sports and disciplines. Why? Because he came up with a method that allows for the traditional effects of a time-intensive, hands-on deep-tissue massage in a drastically shorter period of time.
