Basically a support hold is simply holding yourself up on the rings with straight arms. Eventually, to perform these in the most productive manner, they should be done with elbows straight (almost straight is still bent) and the hands turned out to 45 degrees. To visualize this, simply put your hands overhead in a chinup grip and, keeping that grip position, lower your hands to your side and then let them turn in slightly.For beginning ring strength development I would focus on support holds, front levers, and back levers. Once reasonable proficiency is achieved in support holds, then add dips which in turn progress to muscle ups which progress to handstand pushups which progress to reverse muscle ups (basically a bodyweight curl followed by a handstand pushup).
The rings will move anywhere & anytime within 360 degrees. And the direction they will move will always be toward your weakest area.
