Thank you for visting J3University

I am dedicated to providing you with the highest quality bodybuilding coaching education available, and I have built J3U based on my years of experience competing at the very highest level, peer-reviewed literature, observation in the field of practice, and individual needs/preferences.

This is the reason this site came into existence and likely why you are here even reading this.

You are asking how can I get better?

How do my clients get better?

When I started in bodybuilding, I would have loved to have access to a resource that could give me the understanding of how to coach myself and others.

I would have saved so much time of making the mistakes of coming in flat on stage and getting way to fat in the offseason or being irresponsible with my health.

This site is the culmination of my knowledge and a hub for my continued learning in bodybuilding.

J3U is more than just a collection of lectures - it's a dynamic, interactive learning experience where we will have open lines of communication through our student forums to empower you to become the best coach or athlete you can be.

Join us at the best education platform in the game. Let's make coaching better for everyone!
