Although the RockBlades looks and sounds rather alarming it was a revelation! Lisa used it on my legs and ankles and once I got used to the pressure (firm!) it was an extraordinary sensation. It gives Lisa the capacity to do long deep sweeps and work on soft tissue and connective tissue. I came out feeling like my legs had softened and they honestly felt lighter. The chronic pains and stiffness I was getting have been greatly reduced with each treatment. After three I am now barely noticing my previously sore and stiff Achilles’ tendons!
