RE: Squatting, bar giving shoulder pain
mate, i posted exactly the same post about three weeks ago. Now things are working a lot better, this is what i did:
1) change my grip from wide arm to shoulder width with my elbows facing down,
2) place the bar on your traps, even if they are small it should not sit on the base of your neck, this will hurt like a mother.
3) try and keep your traps tense when doing the squat
I only use a smith machine with the plastic foam in the middle of the bar but i found that putting my towel on the foam worked better as the foam would stick to my skin...........
