We found a Christian exercise program we like called Action 4 Life on 3ABN. We stream it on Roku 3ABN channel at 2 pm central time zone, certain weekdays when it is on.

We also have some indoor equipment the children rotate through. I call them “stations”, and they set a timer for 5 min. at each station, and play higher tempo music with it. We use a personal indoor trampoline, a step, Teeter Popper balance board, and freestyle exercises (like jumping jacks pushups, jogging in place) to rotate through.
I personally have liked videos of Leslie Sansone’s Walk Away the Pounds.
Daily walks are good, too. Walking is the best exercise!
