There are many ways to enhance the abilities of common items. A bar of soap in a sock (especially coming from the army) is a formidable hitter. A wet T shirt or coat is much stronger and heavier in hits than a regular one. A fist is stronger if it is holding a pen and the list goes on and on. As a daily workout, Find a location you frequent or one of chance (think why this place calls for the exercise to be made there or the situation and you will learn about yourself from this) and make a list of at least 50 ways to construct or use what is there as ways to protect yourself and your loved ones. The sand on the beach, the towel hanging over the faucet or anything else goes.
