having just started boxing, I've found that skipping and simple exercises can work quite well. Take simple body weight exercises such as squats, push ups, situps, burpees, etc and do a few minutes of skipping followed by one of the exercises for a minute or so, cycle through skipping and the next exercise without stopping until your set is complete.

It's not perfect, but it can get your heart rate up pretty quickly and can cover a variety of exercises each set. The only equipment needed is a skipping rope.

That said the motivation to do this is a different question entirely.
