Well I don't know but you are all a bit high tech over there.
we use a different kind of monitor here to get fit.
It's called a perentie, needs no batteries at all.About 6', so not huge, just big enogh.
Get one of those , put it in your back yard and he will provide you with all the exercise you need.
He is a meat eater, so no pets.
BTW, we taste like pork and he is a very fast runner.
