Health Challenge: Pick Up The Pace

It's a week before Marathon Monday. Have you started training yet? Sure it's totally too late for this year's 'thon, but how about 2012? Okay, perhaps the marathon isn't for you, but it's definitely a good idea to keep challenging yourself when you exercise. Pick up the pace a bit when you stroll. Or try doing a minute or two of jogging for every five minutes that you walk briskly. If you're already a runner, try sprinting for 30 seconds for every mile you run.

That's the challenge for this week: to pick up your pace. Pushing yourself beyond your normal comfort level can increase your endurance and improve your lung capacity -- both of which can improve the overall functioning of your body. If you bike, pedal faster; swim, kick harder; dance, choose a faster beat.
