I think I complain about this every year so I'm going to do it again. I hate going to the gym after the New Year. For the first few weeks in January there are always more people in the gym than usual trying to fulfill their New Year's pledge to get in shape.
Then February rolls around and all of a sudden people realize that going to the gym is real work and that you actually have to be committed to going. Just doing it on a whim doesn't really work.
For all you people who crowd the gyms in January, only to disappear by February, why don't you save everyone some time and come back when you are truely committed to getting in shape. You can start by putting down that donut.
