A very quick demo of a very quick move! Use this in the middle of circuit training to keep your weight/strength workout pumping your heart, to get in some interval work done for your cardio at the same time! Training with the cardiovascular bursts between strength sets will increase your metabolism - spiking the rate at which your body burns calories for the rest of the day. This is an integral part of one's fitness.
Love this (my clients know) - try it out!
