As an always skinny person who recently started training for 5k micro marathons I must admit I way over estimatedy exercise. I was really surprised after coming back from a 1.5 mile run, sweaty and out of breath, that I had burned a mere 150 calories. For me it felt like it should have been 400 or something, it must be wrong and "I earned these beers". Then it hit me, "That's fat logic!! FUUUUUUUCK!!!!" So now I realize why fats are fat. It's easy to be fat, it's hard to be fit. Well I'll be damned if me or anyone in my family will be on people of walwart. I am up to 3.2 miles on 32 minutes. Nothing spectacular but I am running my first 5k July 4th. Then I am going to wear my 5k T shirt to shit lord fatties everywhere I go.
