If you travel for a living you may not have the time you like for practice.
Take the washcloth in your hotel room, grip like a club. It will give your arms extension and allow you to make your swing.
If you will do this each day as a 10 minute workout session, you will be amazed at the results and how your swing will stay sharp and improve.
It will allow you to focus your mind on what the body has to do to perform the swing. Do it slowly and feel what is happening.
Try it! It works and you will be practicing your swing.
