Shoulder Issues While Lifting, Help Please
Since I got back home from school last week I've been working out at the local YMCA and they have different equipment than my school so I'm still getting used to it. Their fly (for the chest) is different than what I'm used to but it is one of the common ones that I've seen in every gym. I did shoulder raises too on a different machine but I realize the other day I was going too high with the raises, now if I use the fly machine and I set it above 6 (the plates are numbered from 1 to something like 15) I'll be able to do most of the motion but then my left shoulder will lock half-way and I won't be able to finish the exercise. On weight levels 6 or below it sometimes happens but I'm able to do something (I don't know exactly what I do) and my shoulder goes back to "normal" and I can finish the rep and set. Since then I've moved to the chest press instead of the fly, although I still would like to do the fly more.
Has this happened to anybody before? If so, how did you fix it (can it be fixed)? Thanks.
