I’ve been working out on and off for roughly the past 7 or 8 years now. Ever since the beginning, I have always noticed that muscles on the left side of my body are significantly smaller than the ones on my right (and weaker for some exercises). I have been trying to correct this by focusing more on my left side mentally and kind of “flexing” more during movements. For example, during barbell curls, I’ll make sure the bar is completely even so I am not cheating with my right arm and make sure my left bicep is flexing as much as I can.
PROBLEM. For some reason, my left muscles seem kind of “retarded.” It’s extremely irritating. During a set, I will start to feel the burn in my right side of the body but not the left! There is nothing more irritating than doing a set and suddenly getting fatigued but only on one side of the body! I know that I am not cheating with my right side either. How can this be happening? It almost feels as though the muscles in my left arm didn’t “exist” … which is why I don’t feel the burn. I might be a little obsessed since my friends say they can’t notice a difference, but I think it is definitely there.
BTW, I suffered a shoulder injury about 5 years ago and never went to see a doctor for it. It left me unable to move my left shoulder without pain for a week or so but eventually it healed by itself. Occasionally I have shoulder pains but they always go away. I wonder if this has caused all the muscles in my left arm (bicep, tricep, shoulder, even chest) to be unable to develop properly?
I also know I am not psychologically envisioning the whole thing cuz when I wear tight tee-shirts I feel it much tighter on my right side than my left. During some single arm dumbbell exercises, my left arm gives out much faster too
