Another good question was posted on the blog about exercising while on the Master Cleanse:
I started the fast and lasted 54 hours but blew it by being near the refrigerator full of food. I will try it again tomorrow. I am 57 years old and I run a few times a week, does anyone know if this could be dangerous to over exercise while on the cleansing fast?
When you do the Master Cleanse a lot of waste that was previously trapt inside your body will be circulating around as the cleansing process starts to work.
This takes a toll on your body, and is a big reason you get aches and feel fatigued while doing the master cleanse. Doing vigorous exercise will only put more stress on your body.
I would avoid intense cardio workouts and weight lifting while doing the cleanse, especially if you’re doing it for 10+ days.
This doesn’t mean you should stay welded to the couch. It’s good to move around, just don’t push yourself too hard. I like to go for a walk or a light jog, do yoga, and ride my bike when I’m on the master cleanse.
Keep in mind that what one person considers an intense workout might be effortless to another. So if you’re a experienced runner going for a jog while you’re on the cleanse should be fine, but if you’re out of shape jogging might be too much for you to handle.
There is no one rule that fits every person when it comes to exercising and the master cleanse. Just remember to pay attention to your body, and don’t push yourself too hard.
