Level 1 Physique Essentials

This is where every serious coach should start. Level 1 breaks down the entire contest prep and offseason process into repeatable systems you can apply with every client.

Why it matters:

We teach you how to assess, plan, and execute with clarity. This course covers everything from training, nutrition, PEDs, and health assessment.

Applied Hypertrophy Optimization (AHO)

Applied Hypertrophy Optimization (AHO)

Programming doesn’t need to be complicated—but it does need to be intentional. AHO shows you how to build better hypertrophy programs and execute lifts with purpose.

Why it matters:

Understand biomechanics, choose the right movements, cue your clients, and set up growth phases that actually lead to growth.

Female Physique Course

Coaching female athletes isn’t just “shrinking it and pinking it.” This course gives you a deep dive into female-specific physiology, hormonal phases, nutrition, and PEDs.

Why it matters:

If you’re coaching women, you need to take into consideration the unique female physiology and that means understanding the details that make a difference.

I just want to take a second and thank John Jewett for creating J3 University. It’s definitely taken my coaching ability to another level. One of my core traits is the belief that we should always be striving to improve in every aspect of life and his course has helped me to do just that. John has definitely made the bodybuilding world a safer and more intelligent one.

Bro again your university program is unbelievable. That’s every dollar worth it. This is actually priceless information. We’ve all done experimental/anecdotal stuff to ourselves and based that on progression. Until now of course. I see eye to eye on everything you’re saying in these lectures. Hope a lot of newbies will take advice and not fall into the dogma that surrounds so much crap in the sport.

The information is absolutely priceless and the atmosphere they bring is remarkable how everyone is so engaged in absorbing, understanding, and learning what’s being taught. If you’re an athlete, competitor, coach, or just someone that wants to further their knowledge in nutrition and training, do yourself a favor and sign up

I have been involved in health and fitness for over 20 years, and J3U is the most eclectic, comprehensive, organized, and thorough program that I have ever come across. This is the program for you. I can’t wait to register for the other modules.

I’ve spent 5k on certifications that weren’t remotely as valuable as J3. Best investment of my coaching career by far.

John has built something unique, a place for us bodybuilders and coaches that care about progression, if you truly want to level up and learn how to maximize every variable this is the place to be and it covers it all. This course is specific and tailored to us, it carries a huge value for me as an athlete and as a coach

Definitely recommend any newcomer or even veteran to listen to his material because it dissects very important information that we don’t necessarily take into account.   I learned some new things regarding prep ex.  (being longer on gear not having to do crazy things at the end in pre just because and also running a higher AI isn’t always beneficial.   Diuretics was a key topic I loved. We automatically think we need them to be peeled but John goes over how to peak correctly not risking your health on loop diuretics!   All in all very good class and topics discussed and I believe our sport is missing this kind of information that is so valuable especially to newcomers into the sport.

I’ve been asked a lot: Is J3U worth it? The answer will ALWAYS be 'Hands down best money I’ve spent in a LONG time!' You have lifetime access to the modules you purchase, so you can review the info as often as you want.

Not Sure Where To Start?

Start with the same course we recommend to every new coach: Level 1 Physique Essentials. It lays the foundation for coaching success—from training and nutrition systems to PED and health strategies. If you're serious about becoming a results-driven coach, this is your first step.
