Cross Fit

So I just got home from my first Cross Fit experience.  There aren't many boxes in the area, so I found the closet one and e-mailed the owner.  My boyfriend's cousin started there in the summer, but she goes to the morning classes.  She seems to like it so I had high hopes.  The class started at 5:30, but I showed up around 5:15 because I had no freaking idea what I was getting myself into.  I filled out a form and signed a waiver.  The owner was very nice and welcoming.  He had me do a different warm up than everyone else.  I almost did a pull up!! (I've never done one before in my life.)  He had two workouts planned, I don't know how it's supposed to work so I went with it.  First we did three sets of 30-second handstand holds, 60-second forward leaning rest, 90-second side plank (each side) but they turned into 45 second during the second set.  Then for time we did four rounds of 10 dead lifts (@60%) but I just used a kettle bell and I don't know how heavy it was, 5 barbell roll outs but I had an ab roller, and 400 meter run.  Ouch.  That is all I have to say.  The first part wasn't too bad except I'm horrible at side planks.  And the second set of workout was more difficult than I had pictured, probably because I'm used to just running but now I was using muscles that I haven't used in a long time.  The I didn't come in last, so that was nice.  A couple of the people were nice, but others I didn't get a good vibe from.  Being a smaller gym, they had to know I was new.  Maybe I was expecting too much, but I've heard so many great things about cross fit people being welcoming and encouraging that only two out of 12-15 people even speaking to me wasn't what I had pictured.
I think I'm going to check out my boyfriend's box next week.  It's farther and more expensive, but he rants and raves about it so we'll see how I like it.
