Well when I 1st started bac working out it was Monday 200 push ups 250 sit ups tuesday get as many bench press reps in as possible 250 situps then repeat until friday.
Now I'm just kinna doing whatever, I guess experimenting. I tried to do some incline bench 30 mins ago but my shoulder didnt feel 2 good.
Last night I did weighted push ups as well cuz I was hella irritated.
So yea, Idk what I'm doing anymore, I just know, if i worked on my arms & stomach yesterday, i may work on my chest & stomach tomorrow, next day I may do some barbell rows then hit my stomach right after.
You are either doing too much weight or too many reps.
Give your shoulders a rest and only do stretches until they are pain-free, work on back, abs and legs while you wait.
