The Story of Tension Toner
After years of weight training and thinking I knew everything there was to know about exercising, I learned a hard lesson. I was sidelined by a shoulder injury after a routine gym workout.
I was in excruciating pain. Every time I moved my shoulder too quickly or in a certain direction, it felt like I was being speared by a harpoon. My shoulder pain became even worse at night. I would wake up in a cold sweat grabbing my shoulder and trying to massage away the pain.
