Wanna practise a little frugal economics and keep the pounds off at the same time? A study has shown that possibility and best of all, it’s free!

Apparently, as little as ten minutes of exercise increases growth-hormone levels, which helps prevents abdominal fat (nasty nasty things) and increase muscle mass.  A group of women were studied while told to perform aerobics exercise for either 10 minutes at 75% of their maximal heart rate (equivalent of a brisk walk). Blood samples taken after shows growth-hormones levels to be at least 500% higher than before they exercised.

If you’re reading this on your PDA while on the treadmill, set it to 10 minutes folks.
