The BEST 20 minute workout EVER, but could be hard for many!

This is an example of a Sprint 8 type of workout! It's an excellent way to increase fat burning in far less time at your traditional workout, but as with any exercise, you need to be consistent. This is Dr. Joseph Mercola demonstrating. It's worth reading the notes on his website to maxmise the benefit, such as not consuming ANY kind of sugar or sweetner for 2 hors following this workout since it will cancel the physiological benefit! Also, you should only do a Sprint 8 workout 2x maybe 3x/wk, in addition to your standard regimen. Again, see Mercola's page for more details.
