Shoulder surgery, deteriorated disc, herniated disc, spinal stenosis, epidural shots to walk cortisone in the knee, 30% tear in right distal bicep tendon and yet I still lift heavy. I try to always go light and a lot of reps but that doesn't last long. It's not in my blood. I used to have 23in arms.. Miss that shit as they still get big but my right one doesn't quite tighten up and swell all the way like it did b4 the tear. I'm gonna keep on keeping on until my body quits. Why because it what makes me happy, clears my mind,balances my life and keeps my sanity. If I don't lift and lift heavy everything in my life gets fucked up. Been doing it 27yrs and going to do it until I die!
