Just walking on the treadmill, maybe while on the crosstrainer if I can manage it. If the set I get is light enough (or adjustable), maybe even while going about daily business.

I don't suggest using ankle weights for cardio because you'll only make your leg muscles bigger, and end up tiring yourself faster. Leg weights are useful in sports like swimming, karate, taekwondo and basketball (jumping) though. Instead, you could try raising the incline of the treadmill when walking instead, or to simply move at a faster pace.

Squat thrust push ups works well for cardio too. Works your muscles and takes a lot less time than running on a treadmill.
