Was back to my first circuit class in about 6 months, and ooh fuck did I feel it! My legs and arms now have about the same strength in them as rolls of jelly. I enjoyed it though. Except for the beginning where I got some stuck up woman who, instead of kindly and helpfully pointing out that I was doing the circuit wrong (it was a different instructor from my last class) and pointing me back in the right direction, scrunched up her face, and effectively inferred that I was a total moron that cannot follow simple instructions and was generally getting up her snooty nose. There is just no need.
Anyway, once I got back on course, I did pretty well I think. Sweated alot and generally managed most of the exercises without collapsing/throwing up. And am doing it all again tomorrow!
And good news - I'm coming to the Juneathon
