The program says to work out 20 minutes every day. (But I've been averaging every other day) I realized on Wednesday that doing cardio while on this program gives exponentially greater benefits than when not on the program. I did a dance/aerobics class that morning and at 10pm I was still feeling the rush. I need to look up the science of how exercise plays into the cleanse, but let me tell you, the days when you do it as recommended REALLY PAY OFF!!! I felt amazing.
So I'm thinking there's something to do with being "clean" and burning fat from a clean state. Maybe burning fat when you eat poorly causes a release of toxins that prevent the great feeling from being fully realized. Who knows- all I know is, without Isagenix I can exercise and feel pretty good; with Isagenix that same exercise makes me feel AMAZING, and energizes me for hours and hours.
