Dbells will help a little. Going lighter, and focusing on correcting the form will help even more. If you have one side stronger than the other, then try some single-arm lifts for chest on chest day. Same for Tris. Same for shoulders. Same for Back. When I say "single-arm", I mean single arm. One arm at a time. For chest, you can do some 1 arm pressses on the Hammer Strength machine, assuming you have one at your gym. Tris: you have a lot of choices with one arm cable movements. Pick an attachment. Shoulders--1 arm presses on the Hammer Strength. Same with single-arm side laterals on a cable.
