IN for tight pecs.
I too have that exact same problem described with the lovely picture of the woman in a bra. I notice it in the shower, being able to reach further up my back with one hand than the other. Ha. Now you're all thinking of me in the shower (more than you normally would at least).
Anyway, you say tight right pec, well this makes a lot of sense - even being a nomass weakfag I am very aware of my left pec being bigger than my right. Just from feeling about I can feel the shape of my left but the right is quite different.
Years of mousing and one-strapping likely to have caused this? Likelihood of rapid fixing?
