So we now have less than 2 weeks to get ourselves in shape for the big day. And again, if you are like me and have no exciting plans for Valentines Day - you can still use it as a goal. We can all use a push or something to work toward.

Interval training can boost your metabolism and help you burn more calories. You can burn more and not have to spend more time at the gym! It is simply alternating bursts of intense activity with intervals of lighter activity.

For example: Get on the treadmill and warm up for 5 mins at a brisk walk pace. Then alternate 4mins at a even-paced jog and 1min at a sprint. Once you have that down, bump it up to 3mins jog and 2min sprint. Do that for 30 minutes.

You can also do the same thing on the elliptical machine, bike or running off the treadmill or walking (go from walk to bursts of a jog).

Aside from burning calories, you will improve your aerobic capacity (eventually being able to workout longer and with more intensity), decrease bordom and actually result in more comfortable exercise.

See, during intense exercise, muscles produce lactic acid. Too much of it can make exercise painful and tiring. By alternating bursts of intense exercise with easier intervals, you will reduce the buildup of lactic acide in your muscles.

So, try it and let me know how it works for you during the next 13 days. You may see results faster than you think!
