10 Minutes

I only have 10 minutes to do a post, so what's more fitting that doing a post about a quick 10-minute workout when you don't have time for a full-fledged cardio session?

So, if you have 10 minutes, work off of the acronym U.C.M.L. to get a quick, total body workout:

Upper body: Do as many pushups as you can (still in correct form.  And I say, yes, "girl" pushups do count)
Cardio: mountain climbers or running at max speed for 60 seconds
Middle: ab exercises for 30 reps (crunches, sit ups, etc)
Lower: squats/squat jumps for 20-30 reps

Repeat until you've hit the 10-minute mark.  Add in lunges if you want extra lower/cardio combination.
