Too Busy to Exercise? Maybe Not Anymore...


Sure, we've all made resolutions to get fit in 2009 (two words: NIM diet), but we don't always have time to hit the gym or otherwise exercise. Thankfully, some clever researchers in the UK clued in and studied whether doing short, high intensity workouts can be beneficial to your health, too.

According to the British researchers, doing a total of just 15 minutes of high intensity cardio training per day can improve the ability of the hormone insulin to control blood sugar levels and improve metabolic risk factors that have been linked to diabetes.

In the study, young to middle aged male participants performed a total of 6 sessions that were spaced out, and did 4 to 6 30 second sprints per session. A total of only about 250 calories were burned per week but the ability of insulin to act on blood glucose was remarkable.

What can this mean for you? Even if you are too busy to head over to the gym or do long bouts of cardio, you can still take a step in the right direction. Be efficient: whatever cardio you do, do it hard. Take the stairs at work. Be a minute late for the bus and run to the next stop (OK, that one's pushing it a little, but you get it!). Use whatever time you have a little more wisely and you might just surprise yourself...and maybe your doctor, too.
