THIS
Trying to gain strength/muscle mass super quick is a near-guaranteed way to get injured -- which, in addition to majorly sucking in and of itself, will prevent you from training for awhile, and set you way back, accomplishing exactly the opposite of what you want.
Slow and steady is always the way to go. Push your body to its limits, sure, but don't try to push PAST those limits.
Anyway, as for my own status, since I haven't updated in forever:
I'm officially retired as a competitive gymnast, but I'm still doing enough rings training to stay in pretty good shape. Still got my iron cross, my planche, my nakayama (pull from back lever to cross), my maltese on a good day, and my azarian (backward roll to cross) on a great day.
My diet is what really needs work -- it's been inconsistent and unhealthy, and I'm absolutely positive I could be in much better shape if I ate better.
