You should be holding onto the bars with the same amount of force it would take to hold a baby chicken (I was going to write chick, but some smartarse would be bound to say something). Your arms should be parallel with the ground, or as near to as possible without being uncorfortable and your elbows tucked in.
Try this:
crouch down in front of your desk so you are sitting on your haunches and hold onto the desk. Try moving your upper body around. Easy huh?
Now try holding onto the desk but with your body at a 45 degree angle, and your body and legs straight (kind of like a push up position, but leaning on the edge of the desk). Now try and move around. This is the way a lot of riders ride (not the position, but the stress on the forearms and wrists). Stress on the forearms and wrists causes tension in the shoulders, which is counter productive to effective counter steering.
Learn to relax and everything will feel better.
