I have a book, it's called No Excuses by Harvey Walden IV, I think he's on one of the weight loss shows, he's a Marine who inspires people to exercise, boot camp style.
The book is broken up into stages, I am doing the Stage One, Get Off Your Butt, sometimes when I am at home and miss the gym that day or don't walk. It takes about half an hour and consists of exercises, broken up into 30 second spurts, with 30 seconds of marching in place.
I didn't get a chance to do it today, so when TJ comes home from school, I ask if he wants to exercise with me. "Yes!" he does, he tells me. I'm worrying that it will be too much for him, he's had a long day already, but I figure we can stop if it is too much for him.
So we do it.
The marching part turns into fun, with TJ saying "I am the leader!" and yelling "hup, two, three, four" with me chasing him around the room. We are both laughing.
I teach him how to do lunges, somehow he already knows how to do push-ups and crunches. He does the cutest "steam engines" in the world with his hands behind head, elbows out, alternate touching knees with the opposite elbow. He gets the concept, sort of.
We finish all the exercises, do the last flutter kick. "Woo!" I say, "great job!" and give him a high five.
"Let's do it again!" he says.
