If you have a pool table at home, ensure you are practicing in the same attire that is required at your tournaments. It will help you to practice in the clothes and shoes you would be wearing at an event.
- If you don't normally wear glasses, don't wear them to practice when you are on your home table.
- Don't wear slippers or don't go barefoot - the difference in height and feel is amazingly different when you wear your comfy shoes for an all-day event.
- Wear the type of shirts and pants you would play a tourney in to get used to them. If you always wear your jeans, and your next big event requires slacks and a belt, will you be comfy?
As everyone knows, being comfortable is an important element to playing pool. Let me state this in a louder voice: Being uncomfortable can hinder your performance.
Give yourself a better chance to be better prepared by practicing to the optimum.
