A workout for busy people

If your workout needs a face-lift, try this for a change: Get on a cardio machine (or run stairs in your house, or run around the block, or jump rope) for 5 minutes, working as hard as you can. Then, do 20 push-ups and 20 tricep dips. Repeat this cycle a total of 5 times, beginning and ending with the cardio intervals. You'll end up with 30 minutes of intense cardio and an upper body workout targeting every major muscle group. Top it all of with crunches (twist side-to-side to target the obliques as well). Do 100 very slow crunches, and then 100 quick crunches.
