Ok, 3 weeks ago during skullcrushers, i lost control of the bar and i felt my right shoulder pop. Sure enough, for the past 2 shoulder workouts, i cant go all out. I normally only do dumbell presses (vertical) and miitary press for my shoulder workout. What are some alternatives to these???

Lots of good alternatives to the standard shoulder presses:
