Briee, I was going to answer your pull-up question to Maximus on that thread, but now that you've mentioned my name on this one (which, by the way, has 13 0's -- not 10), I'll answer it here.
I couldn't even do one pull-up, but the way I got up to doing 824 of them was by pulling myself up one millimeter higher every day for 19,776 days (which = 54.18 years). I've learned on this forum that it's always better to increase incrementally (be it cardio, strength, flexibility or whatever) in order to avoid injury, so that's what I did with pull-ups. Once I get to 1000, I'll try them in reverse like you mentioned.
