Irulan, yes, we went to Coba and loved it. We got dumped on and drenched but still enjoyed walking around (it was really too wet to ride; think rivers flowing down the roads). Thankfully we were able to climb the pyramid before the rainstorm; I can't imagine trying to come down those steps when they are wet!!

katluvr, my friend that is into Crossfit actually has a Crossfit coach. She has 3 sessions with him each week (I think they are an hour) and she sends her a daily exercise every morning. She is an ultra runner, and was in really incredible shape before she started Crossfit, but still claims that it's taken her to a new level as far as muscle endurance is concerned. There are certified Crossfit coaches all over; I suspect they have programs for specific goals like you mention.

LG, I read two books in their entirety and almost finished a third!

SBS, clothing definitely optional, but not too many naked folks. Mostly just topless women.
