HOD made it very easy, because I'd already taught my dc basic calisthenics from the HOD guides. HOD had taught my dc to run in place, do jumping jacks, sit ups, push ups, bounce a ball, windmills, and toe touches. I added leg lifts, boxing (because we have a kids' punching bag and gloves), and a few simple stretches to round it out. That makes 10 exercises. I put each one on an index card, numbered them 1-10, and hung them spaced around the ceiling in our basement spare bedroom that has now really become the playroom (except for the bed we left in it ). I got a timer, started my middle ds on Exercise #1, my oldest son on Exercise #5 (to spread them out), and let my toddler just run around. I first set the timer for 2 minutes for each station, but that was way too long as my boys haven't huffed and puffed that much in awhile. So, we stopped and did 1 minute stations, but did them twice. This resulted in a 20 minute workout. They already want to work up to 3 rounds and 30 minutes of workout, but they're way too sore. Maybe in a month. 
They were so excited about it today. I'm sure it'll wear off eventually, but it's great for now. I figure it'll be easy to add things in or take them away over time too. Here are some pics to help make this clearer:
Running in place 
push-ups 
sit-ups 
bouncing the ball 
jumping jacks (my he looks like a hummingbird! ) 
leg lifts 
punching bag 
toe touches 
windmills My toddler ran around and actually did a few sit-ups, jumping jacks, punched the bag, and threw the ball to me. He also played with the pool stick, rocked on his rocking horse, and dragged out the knights and castles. That's o.k. My goals for him were to have him move a little, be generally happy, and not get trampled.
This worked great to get the wiggles out of my boys and have them get in some healthy exercise without having to leave the house, and without buying anything. I plan to play the Beach Boys exercise music for them once they get the circuit down better, and who knows, it looks so fun I may join them!
Maybe this idea would work for someone else! All of your dc using HOD probably already know these moves, so that makes it super easy to start this without a bunch of teaching. Just thought I'd share this for fun!
In Christ,
