When I'm short on time I do the following routine that I got from my wife's fitness mag:

3 sets of 12 reps descending / ascending of:

* frog jumps - plank pushups

* reverse lunge with overhead press - spiderman crawls

* burpees - leg raise sit ups

Eg: do 12 reps of of frog jumps and one rep of pushups, then immediately do 11 reps of frog jumps and 2 reps of pushups, etc down to 1 rep of frog jumps and 12 reps of pushup. NO resting in between. When done, take a two minute rest, then immediately start the next set. The key to this routine is not resting, and maintaining good form. It offers me a great burning sensation when I do it correctly, and I'm done in less than 25 minutes flat.
