Here's what I learned after my first week back at the gym. First off, I got a decent baseline of what amount of weight I can lift. Second, and more importantly I found my stability muscles in my left shoulder are weaker than my right and I'm unable to push the same load for the same reps. It's also making my form messy the deeper I go into each set as it fatigues. I find this also when I add more weight in my squat, my ass tended to move out to the right instead of stating in a nice straight, neutral line.
So, I'm going to step back, revise the workout routine I had made to focus more on strengthening my stability muscles because I don't want to cause any injuries or make my right shoulder worse since I had hurt it while taking a fall snowboarding a couple years ago. Doing certain exercises are causing pain in it.
