Pushup Position. Begin
One rule we have in the new office that I share with two others is that every time you enter the office is that you must complete pushups. We started at 10, increasing one every day.
This is done for two reasons. The first reason is to increase personal physical fitness. If you are forced to do pushups every day then you will do a better job on the fitness test. Second reason is to keep unwanted visitors out of the office. On the first visit you are informed of the rule, every time after that you will comply.
There is no reason for me not to max out my pushups in a few months.
