When it comes to exercise, the erganic principle of intention tells us to use our body as our primary “machine” 80% of the time, with a few exceptions such as a jump rope, pull up bar, dumbbells, kettlebells, etc. Some of those traditional “machines” can apparently be a bit trickier than meets the eye.
So while we do often recommend the treadmill for some potentially wicked calorie burning intervals, be warned … it can get a little ugly … (especially if you attempt a pogo stick or a bike on the thing;) Enjoy.
