Yes, all of those. I used incline, assisted, and isometric holds to get it the first time. This time, I first had to find a way to do any push-ups pain free (see thread
Other/Mixed - Painful push-ups - front delts) but I'm currently doing pretty well with the Shenaboard and letting the elbows come out towards 45 degrees. I also started physical therapy last week; the diagnosis is tight/weak/inflamed rotator cuff muscles so treatment is 4 each stretches and strengthening exercises for infraspinatus, supraspinatus, teres minor, and subscapularis. So we'll see how it goes from here.
