I'm guessing a couple of the instructors at my Jazzercise class had a bad week - because we did a ton of kick-boxing routines.
Just how bad is it for me to admit that I had a person in mind for each punch or a kick. Imagining that face at the end of my fist was cathartic and I'm pretty sure my punches were much harder which means I got a better workout.
A great reminder of the reason Jazzercise is so great for me - I get a good workout and I get to take out all my frustrations so the don't stay bottled up and keep me up at night.
One of N's favorite kick-boxing routines is to Madonna's "Celebration." Listen, and if the spirit moves you, put your arms up and start punching. Don't be afraid to imagine there is a face at the end of your fist, after all it is only imaginary violence.
