I am going to admit it, I suffered from gym retardidiss, a condition in which one works only the muscles they can see, and does chest almost every other day. For about 2 years, working chest was the highlight of my week, so I integrated it into my lifting schedule as much as I could, even if that meant 2-3 times in a 7 day span. The results were addictive, both in the mirror, and in the gym.
Being able to rep at 265 (5’11" 165 lbs) gave an almost drug like feel, and I didn’t really see a reason to stop. That was until I started to notice the severe pronation that my arms were experiencing, and the more crippling pain in my AC joint.
By being so focused on pushing, and building the muscles in front of me, I created a tremendous disparity in the balance of my body. Not only had my arms started to creep in front of me, but the smaller muscles were thrown out of wack, and slowly started to get pissed off.
Busting your AC joint is not fun, nor is creating severe muscular imbalances in your body, so I just want to use my story to underscore how important it is to work towards muscular balance, and maybe even focus more on the muscles behind and below you, rather than what’s in front of you. It might not be painful, annoying, or awkward looking now, but it will eventually reach that path if your busting out chest and arms everyday of the week.
Eventually I reversed the trend, and took the long and painful path back to correcting the balance. As annoying and frustrating as it might have been (cutting chest out completely for a month), the end result was a much more balanced muscle composition, that looked better in the mirror and felt better on the move. Every motion has an opposite motion, and every major muscle has minor supporting muscles. Make sure you focus on both of those, and you will enjoy better progress, and a more pain free path to greater muscle.
Bottom line, work towards balance, in your lifting, and maybe in the rest of your life. Doing so will lead you down a good path, and won’t force you to back track and carve your way back to normalcy.
