Hi,
thanks for your answer kidcolin. The uneven loading might apply to me as well as i found out that some of the barbells in my gym are heavier on one side than on the other. Not very much, but that might have accumulated over time.
At first i thought it must be me but some buddys confirmed that feeling.
Im going to pick my barbell in the gym a lot more carefully from know on..
Unfortunately i dislocated my kneecap last sunday and i'm out of action for a week or so.
