Fasting for Fast Results

About me


The goal is to find balance in maintaining lean muscle mass, looking defined, feeling good and slowing down or even reversing the effects of aging.

Well hello there! My name is Kevin David Rail and let’s cut right to the chase. I have a B.S in Sport Management/Fitness & Wellness, I’m a Fitness Nutrition Specialist through the American Council on Exercise (ACE) and I am certified through the American College of Sports Medicine (ACSM), National Academy of Sports Medicine (NASM) and Art of Functional Movement (AFM) as a personal trainer and movement specialist.

I have 25-plus years of experience in my field and have been featured in two critically acclaimed documentary films—Fasting and The Motivation Factor. I am also co-creator of the health and fitness app My Inferno Body and have produced content for such companies as Life Fitness,,, Wild Warrior Nutrition and GarageFit.

My main focus is to raise awareness in men on the connection between fasting and fitness, and to motivate, inspire and educate people to live the best life they can while reversing the aging process.

I do workshops related to restorative arts, classical exercise, kettlebells, fasting, gut health, mental health or a combination of all of the above. These are interactive, fun and thought-provoking.

Fitness tools like Indian clubs, health wands and gadas are presented in some of these workshops, which are some of my specialty implements. They bring a massive amount of benefits to the brain and body, and a lot more people need to know about them. Additionally, I do in-person and virtual seminars and shopping tours.

The cost for these services is variable. It depends on the length and amount of people who will be in attendance. Often times though I include the price of fitness tools used in the fees.


My Inferno Body App

This is the app that I co-creating with my friend, Jill. We have an abundance of content that includes a workout and exercise library, pre-made programs, fasting protocols, dietary diversity guides and our signature cookbook. All of the content is only $4.99 per month as long as you are subscribed.

I am a bigtime loyalist when it comes to brand association. I don’t promote or endorse any company with sketchy ingredients or evil people running the show. This has already been addressed in the Firing Squad section.

If you are looking for supplements, foods, fitness equipment or apparel other than my personal t-shirts, then here is a list of good-quality brands that get my Seal of Approval.
