Some background: about 2 - 3 years ago, I moved from lifting dumbbells to barbell compound heavy lifting. The core of my workout includes bench, squat, and deadlifts. After about a year, my left shoulder got so sore that I could not sleep on it. I gave up lifting altogether for about 6 - 8 months and focused on sprinting and high intensity cardio. Of course, I lost way too much weight that way, but my shoulder improved. I switched to pushups, pullups, and chinups, and had no problems.


For reference, I'm currently 37 yrs old.
