Burpees are for people who hate form, hate supporting their body the whole time, and hate puppies.
If you are the type of person who loves form, body support AND puppies, then you should do things that don't involve some sort of rushed, fish flopping around in the ground move. I mean, really, you end up laying on the ground for a second? And that is "work'?
We do these (because my group is instructed by a former SEAL):

You can search for "8 count bodybuilders" for a few variations, but they're all the same series of moves.
Variations are remove the sideways kicks, and/or remove the pushup (so clean, systematic squat thrusts). Weight is always on the arms, motion is systematic and rhythmic, controlled. They take much longer than burpees but that's because you're not trying to break something.
3x10 Bodybuilders will kick your ass. When it's someone birthday, we toss in that many 8-counts in addition to the normal workout. I had to lead us through 45 of them last week
