J3U HUB — WHAT IS IT?

The free home base of J3 University — John Jewett’s community, lectures, and tools for coaches and competitors.

Applied Lab

For the person who has done the reading and now wants to watch it applied

An ongoing membership rather than a course. A library of recorded member calls where real case studies get worked through, adjustments get argued out, and member questions get answered live. It shows the reasoning behind a decision rather than the conclusion, which is the part almost no education gives you.

Inside: Years of recorded member calls, added to on an ongoing basis.

You can also join the free hub, tap the community, and use it as the launchpad into J3U courses, programs, and coaching.

RP Strength provides science-based training and nutrition systems that athletes worldwide trust. Their evidence-driven approach turns complex sport science into simple, effective plans for fat loss, muscle growth, and competition prep without the guesswork.

The RP Hypertrophy App

• 100+ premade plans — full-body, timesaver, body-part specialization, and pro-style templates so you can start immediately
• Meso Builder — choose which muscles to emphasize, grow, or maintain; the app builds the block around those priorities
• Progression planned for you — target weight and reps each week, with load, reps, and sets updating as you improve
• Autoregulated volume — pump, soreness, and workload feedback steer you between too little and too much
• 250+ technique videos and a growing exercise library, including custom movements and equipment filters
• Edit in the gym — swap exercises, add or drop sets, change order mid-session
• Automatic deload — the last week of each mesocycle is built in so fatigue resets before the next block
• Copy a finished meso — rebuild a successful block in a couple of taps

Science-based muscle growth: templates or Meso Builder, then week-by-week progression from how you actually recover.

J3U LEVEL 1 — WHAT IS IT?

The core physique education course from John Jewett and Luke Miller — the system J3U uses to train coaches and competitors. The gold standard for bodybuilding education.

Level 1: Physique Essentials

For coaches and serious competitors who want a system instead of scattered information

The foundation, and the one that opens on a monthly window. It is a structured, evidence-based framework for physique development that holds up across every phase of the year, built for competitors who want to understand the decisions behind their own prep and coaches who need something repeatable they can run across a whole roster.

Inside: Nine modules covering coaching foundations, recovery, nutrition, hypertrophy, health monitoring, offseason, contest prep, and the post-contest phase.
