Left arm is doing more work.

[CastorRuss]

I just started doing a lot of compound exercises and have realized that there's some kind of imbalance between the left and right sides of my body. On a bench press, even with dumbells, I'll feel that my left arm is getting more of a workout, i.e. it feels more strained. And I'm left-handed, so I would think it would feel less strained if anything.

This is probably related to something I recently noticed when i go to do crunches. If I lie flat on my back with my hands behind my head, my right elbow can easily/naturally be stretched to the floor, while I cant really get my left elbow to the floor if I try. It almost seems as if my left shoulder blade is larger and slightly titling my body to the right.

I've tried focusing on using the right arm, and adjusting my grip a little to put more pressure on the right, but this hasn't worked too well and am not sure it's good for the workout.

Any ideas?

It sounds like you need some mobility and corrective work. You're already doing some DB work to give both sides equal loads but consider adding an extra set to start bringing up the lagging side.

Hartman is a guru of corrective work. Cressey and Robertson also have a ton of good stuff on the topic. Look into some of their articles, programs and even DVD's.

If you keep up with the imbalances chances are it will lead to getting hurt.
