Yeah, no running for me. At 300 pounds with a power lifter build it just does not work well. I am getting back on my diet and I am hoping to drop some major weight over the course of the next year. I have had a lot of troubles with having a gotta be big mentality that I guess I developed over the course of my lifting career that has been really hard to shake, but the toll it is taking on my body these days I HAVE to do soemthing.
