Trying hard to size up them bi's

My new routine is called No Days Off. My current goal is make sleeves go extinct. 🤘

Chest pounding complete; pecs begged for mercy

Bear-hug Medball Squats Not my favorite exercise but good for cardio, butt, and testosterone production. Just doing the work, folks.

Messed up my back doing standing dumbbell shoulder presses, I guess I put too much weight on my lower back and it took me out for a few days. Any recs on how to keep doing shoulder presses but not repeat this? I'm thinking incline bench... recs?
