Keep your clothes on!

I had a normal day at work and then went to my first gym class... bums, tums & thighs. It was great but soooo hard. I was confronted with the normal gym change room behavious though, the older ones just walk around naked! One gets completely naked before taking off her shoes...why? I dont want to see it. I could tell I was going to feel it later. I even walked home! It's a 25 minutes walk! Go me!
