A Piece of cake!

I'm Richard Stewart and I'll tell one story which happened with me and my wife. My wife's name is Marilyn. One day she return from her new advanced exercise class. She was very tired and she said that this new exercises is too hard for her. I can't believe on it! I said that aerobics - it's very easy and i wouldn't feel a thing working the class. She was very surprised but i  said that i would do it without a doubt! She can't believe me, she just laugh at me and offer to make a bet :  if I'll lose I'll cook dinner for the entire family and if she'll lose so she will do it.I really thought aerobics is easy! 
When i came to this class the coach Jack Davis offer me to made some photos for advertising instead of doing aerobics.I agreed, but when i came home i told Marilyn that in the aerobic class  was perfect and that i am not tired and that I'm in excellent health! I won, but I didn't feel it because I lied to my wife. And then, in the next morning ,i told her truth because i can't keep it anymore! After that we went to the class together and cooked dinner for the whole family .But when i came from the exercises non-stop I was exhausted! It was awful! I couldn't even moved! My whole body achesed! 
So now i understand that aerobic it is not so easy!!!!)))))
