Look at the picture. My left pec is way bigger than my right.
When I bench press, sometimes the left part of the bar goes up faster than the right.
However, when I DB bench press, my right arm goes up faster than my left… weird.
Anyway, what can I do to correct this? It really really annoys me. They used to be equal. My friend has the same problem, and his pecs used to be equal as well.
