Next time you hit the head, work on your pull-up!
- Using either the door or side wall of a bathroom stall, grab hold of the upper edge.
- Either jump to the top position or (if you can) pull yourself up.
- Hold for a 10 count.
- Carefully lower or drop to the floor.
- Increase the amount of time you hold the top position each day.
A word of caution - please be careful and make sure that the adjacent stall is empty. It will be very difficult to convince someone that you're working on your pull-up skills and are not, in fact, a pervert.
