I mix it up on the Tabata drills but one I just did a few days ago was:
Kettlebell snatch right
Kettlebell snatch left
That's 20s work /10s rest, repeat it 2-4 times for a 4-8 minute workout. That's pretty typical. I'll also do Tabata with things like body weight squats, push-ups, kettlebell swings, Ugi ball taps or high knees, box jumps, anything I can blast for 20 seconds. And I don't always mix it up with several exercises. Sometimes I'll do all kettlebell swings, or all burpees.
