Recently injured shoulder. Assumed the worst (SLAP tear, rotator cuff, etc). Turns out I have early signs of arthritis and have a small piece of cartilage in joint, significant sharpening at top of humerus bone already, not good at age 32. Long story, short....Doc says no more "heavy" pressing. Wants me to keep my rep ranges higher, even then Im probably still screwed, but Ill deal with that when time comes.
Question is, i just started HST and I love it, if I wouldve start this 10 years ago I probably wouldnt be in this situation. But I dont feel comfortable doing the 5 rep range on pressing exercises (bench, dips, any shoulder press). Would it be extremely detrimental to the program if I did 8's instead of 5s on those few exercises?
Not detrimental at all to keep the rep ranges higher. I think HST is actually a great program for people with problems like this as most of the loading is submaximal and you get ~9+ days completely off between cycles.
My suggestions for a guy with a screwed up shoulder:
* Figure out why you hurt your shoulder. This could be form-related, obviously. I.e. make sure you have good pressing mechanics in stuff like benches, dips, overhead press and so forth.
* For the time being, don't use any movements which cause noticeable aggravation to the area. This is a fine line, but anything that causes lingering pain afterwards should be excluded for the time being.
* With a set of exercises which don't seem to bother the shoulder, proceed as above, perhaps keeping the rep ranges a little higher (something like 15's --> 12's --> 8's would be fine, for instance).
* Try to actively rehab the area. Figure out if you have disparities between sides in stuff like shoulder external rotation, for instance. Do PT-ish exercises to help correct these. No need to be aggressive here - perfect form, very slowly incrementing the loading over a larger period of time.
* Consider pushups - I throw in some pushups a time or two a week as they seem to help train stuff other pushing exercises don't, most noticeably serratus anterior. Obviously these will be implicitly higher reps, and there's no reason to go crazy here.
Just some thoughts and how I'm addressing my own shoulder injury. Best of luck.
