Exercise Scientist Critiques the Most Jacked 19-Year-Old : Natty or Enhanced?

TL;DR

Dr. Mike from RP Strength analyzes Julian Fitzgerald's physique and concludes he's likely natural, citing elite genetics and West African descent as explanations.

Key Points

• 1.Julian Fitzgerald is 19 years old, 5'11", and weighs 195–200 lbs. Dr. Mike uses these stats as a baseline for his natty-or-not assessment, noting his arms are disproportionately impressive compared to his shoulders.
• 2.Dr. Mike rates Julian's natural probability at roughly 60% likely natty. He argues that genetic variation is far wider than most people assume, with outliers 3–4 standard deviations out capable of building 20-inch arms without steroids.
• 3.West African genetic heritage is cited as a significant physique factor. Dr. Mike argues that Black Americans frequently display exceptional muscle-building capacity naturally, and that European audiences underestimate this due to limited exposure.
• 4.Julian's bicep peaks and tricep sweep are described as almost entirely genetic. Dr. Mike explains that muscle belly shape — not just size — is largely determined by genetics, and Julian's 'peak on a peak' bicep shape is a rare natural gift.
• 5.Rows should be performed with intentional rounding and arching to build back thickness. Dr. Mike clarifies that rows primarily target spinal erectors, rhomboids, and traps — not the lats — and that lengthened-position exercises like pulldowns and pullovers are superior for lat growth.
• 6.Dominant muscles like Julian's arms can hijack back and chest exercises. Dr. Mike recommends isolation movements and mind-muscle connection to ensure the target muscle — not the arms — is the limiting factor during compound lifts.
• 7.Julian bench presses with a close grip and nearly vomits post-set. Dr. Mike explains the close grip favors his arm-dominant strength profile, and attributes his near-fainting to blood pressure redistribution causing lightheadedness and auditory changes after heavy effort.
