Step One: Have an over-inflated confidence in your ability to hang with, say...the class.
Step Two: Put on your best Bruce Lee face and act like it doesn't hurt that much...really.
Step Three: Suppress those crying and vomiting urges. There will be plenty of time for that after class.
Step Four: Don't be terribly intimidated by the fact that even your earlobes are sweating.
Step Five: Please, oh please, don't break wind during the final stretches.
Step Six: Go back to class again on Wednesday and repeat.
