I've been exercising every morning lately (pushups and situps), and am looking for ways to optimize my morning routine without it taking too much time.

So, where can I find good tips on a morning ten-minute exercise routine, that doesn't require any special equipment? Preferably from a credible source.

I'm not trying to lose weight (I'm pretty skinny as is), just to be healthy.

(I found some tips here, but it's a bit more than what I want to do right now, and requires a Gym)
