I have found the fountain of youth for sore, worn-out lifting joints and muscles. It is Sound Assisted Soft Tissue Mobilization.

I call them "The Blades of Death". If you guys have someone in or around the area certified to do this.. DO IT. It is really for rehab, as it breaks up scar tissue in joints or muscles, and lets it heal properly. If you have been lifting weights for many years and have that nagging shoulder issue, this will fix it. I did not believe it until I went. My shoulders, after 20 years of lifting, never felt so good. I go a couple times a month when training.
I will also tell you it is painful (aka Blades of Death), when the process is going on. It hurts like an SOB, but it is worth it. You will not be able to stand more than 15-20 mins for a session.
They essentially take those blades and can work in the different layers of the muscle, or the smaller tools and work into the joints.
