I would like thicc hams

The other day my back went out. I hurt it carrying a 100lb generator, normally carrying 100lbs isn't too bad for me but I slipped in some mud and twisted my back but didn't fall. That was in January during the big storms. We had a power outage which is why I was lugging a generator around.

Anyway, Its been in and out for the last 3 months. I decided to do something about it. I don't have room for a full size power rack. This is a trap bar. While my back is healing up I loaded it up with 70lbs and the frame weighs 30. I'm doing dead lifts, squats, shrugs. I also have a curling bar coming and a lot more weight. 100lbs just isn't heavy enough.

My legs are strong, my shoulders are strong, but my lower back, core, glutes, and hamstrings need work. My chest and arms also need to grow. This will get me my way.
