A year or two ago i use to do dips all the time at the gym. I would usually work up to having a 35lb plate hanging from my belt. I stopped doing them for awhile because i changed routines, plus i sort of hurt the back of my left shoulder possible doing that or something else.
Anyways, i tried to do them a week ago with no weights at all and they were tough and afterwards i felt some pain in the back of my left shoulder, possible rotator cuff problem? I haven’t done them since because i don’t want to mess up my shoulder at all. Is this a normal thing and is this just an exercise i should avoid from now on?
