I wasn't made for sport. I'm dying.

Never practiced sport before.
But this month I had this terrible idea of starting fitness classes.
I had one hour yesterday, and now ( it's 6 in the morning here ) I have unbearable muscle ache. It's as if somebody was hitting me with a wooden stick. Can't even wake up from bed and go to school.
If this shit doesn't pay off by making me lose my damned 3 kilos
I'm murdering all people at the gym.
