re: Shoulder issues after bench and flys still happening, recs please?

Same here just strange to have little to no feeling in fingers still.

I've always had issues with shoulder impingement any time I'd try to start lifting... Until recently.

I started lifting again a little over two months ago and quickly had the same ole issues with my shoulders. I decided that it must be something I was doing wrong and did as much research/practice of proper form as I could.

The two biggest cues that will help you prevent shoulder injury are to squeeze your traps together before you unrack the weight and to "row the bar". At first the second one made no sense to me but if you've ever seen a properly performed bent over barbell row it will make total sense.

Finally, I've started doing dead weight hangs to relieve shoulder pressure and gain more shoulder mobility. There's research to suggest that doing dead weight hangs with a thumbless grip 5-7 minutes a day can cure most shoulder problems.
