Most people who have been coming over for a visit cannot do everything at "full power" in the beginning.
Um, I STILL can't do everything at full power after a couple of months!
Plus, the minute I accomplish something like headstand + lowering my legs slowly without falling over, Ark and Chu add a new thing! These people are crazy.
Actually, I think one of the primary hidden benefits from the whole routine is precisely that because it's so many different things, you can never do it all perfectly. So, it's a constant challenge, and you choose how to respond to that challenge. Do you get frustrated and give up before you even start?
I decided to just sort of focus on a few things, like: Do a better headstand, and improve balance (last exercise), and increase flexibility (for the legs apart in front of you, and then lean forward). The rest maybe I'll deal with later. For example, I really, REALLY can't do The Pretzel (where you're sitting and your legs and arms are all twisted together).
But I'm not so worried about upper body flexibility like that. It literally seems impossible for me to do. Maybe it is, maybe it isn't, but I just decided that's not one of my goals right now. Maybe later after headstand, balance, and lower body stretchiness.
Sometimes, it's fun to just to sit - and rest - and watch other people do something that I can't do!
Plus, every day is different. Sunday, certain parts were a bit tired since I went running on Saturday. Today, one of my feet was cramping. Tomorrow, who knows...
