I am in no way a bodybuilder, but i try to keep a reasonably trim physique eg press ups about 150 throughout the day, then the next day the same for crunches then alternate etc. I dont particularly intend to go to the gym, but i was wondering why it is that my left pec is bigger than my right. It looks a bit silly and is also surprising seeing as i am right-handed which would leave me to expect my right one to be bigger. Any ideas as to how to remedy this without using gym machines, and if poss without weights, although feel free to advise as i do have weights, just not at uni (small barbells designed for bicep curls i assume). Thanks...
