Rain, rain, go away!

So yes, today is raining and it's disgusting out. It's also pretty chilly, and to me, that simply means summer has come to an end yet again.
I went to the gym for over 2 hours today! I did 40 minutes of cardio, 20 minutes of weights (approximately,) and I took a Zumba class. Which didn't go so well. Right at the end, there was about 10 minutes left of class, I pulled a muscle. It was around my butt and it did not feel good! The class itself is pretty out of my league, I made a complete fool of myself, but I wasn't the only one. I actually really enjoyed it though, and I plan on taking it again next week! Hopefully I won't pull another muscle...
Then, as I was stretching out to make the pain go away, this personal trainer approached me and offered some help with this new machine that would really help stretch out and relax my muscles. It was wonderful, but I learned something quite unfortunate.
Turns out that my body is all messed up from carrying all that weight on my left shoulder. I'm incapable of having it on my right shoulder and it's really starting to show on my posture. She says I have a mommy body and I don't even have kids! She also said that if I keep this up, I can develop Scoliosis and that's something I most certainly do not want! She told me, she ordered me actually, to start carrying my bag on my right shoulder otherwise I am really going to regret it. So, I'm trying, but I'm struggling. I really don't want to be permanently damaged.
Anyway, that's all for today, I have some studying to do.
XOXO,
