minor shoulder tendinitis

NCULEFT,

I think the key thing here is you said "I think".

Unless you have had tendinitis before and know exactly what it is I wouldn't take anything for granted. I suggest you talk to your team trainer or doctor if the pain/irritation persists.

I don't think anyone on this website could/should tell you if you should try to do your weight lifting workout through any shoulder issues you may be having.

I hope it's nothing but suggest you be safe rather than sorry.

NCULEFT,
I'm going to give an answer based on a pitcher that has tendonitis. If you have pain that persists more then a couple days I would suggest that you talk to your trainer or a physician. If I'm working with a pitcher that has tendonitis I will do everything possible to help increase blood flow to the shoulder. I will normally combine running , stretching, and my Shoulder Program while the athlete is at practice. An example of this would be:
1) Jog 2 foul poles (over & back = 1)
2) Upperbody Flexibility Program (same as before a game)
3) Sprint from 1 foul pole to the other & then jog back.
Do this 3 times.
4) Upperbody Flexibility Program (throwing arm only)
5) Shoulder Program - 10 Reps.
6) Sprint from 1 foul pole to the other & then jog back.
Do this 3 times.
7) Upperbody Flexibility Program (throwing arm only)
8) Shoulder Program - 8 Reps
9) Sprint from 1 foul pole to the other & then jog back.
Do this 3 times.

This is an example of something that we might do on M/W/F.
Normally after a week you shouldn't have anymore problems.

In regard to your lifting. I would still lift your upperbody
twice a week, but I would only do 1 exercise per bodypart,
and keep your reps high (15-20) and your weight light.
I hope this helps you !
Good Luck - Kerry
