4-Day · Weak-Point · Members OnlyAvailable

Arm & Delt Specialization

Justin Harris's arm and delt specialization program — the weak-point version of his 4-day bro split, built on ultra-high volume with strict form instead of weight-chasing. A subscriber exclusive: only in the TroponinIQ members' library.

The books that answer back

Every title here ships with a coached edition built to run alongside SuperTrop, your TroponinIQ coach — and the coach is trained on the material. It remembers your numbers between sessions, tells you when a stall means swap the movement, and scales the nutrition to you. The book gives you the framework; the coach applies it to your body in the mirror.

Books & programs, answered

Are the training programs really free?

The training library — the Power Bodybuilding Bro Split, Critical Mass, the original Power Bodybuilding, and the Arm & Delt Specialization — is free with any TroponinIQ subscription: every book is readable in your account, no separate checkout. The Troponin Peak Week Protocol textbook is the one paid title on the shelf — $199 one-time, with a 20% subscriber discount applied automatically at checkout.

Do I keep the books if I cancel?

Books you buy outright — the $59.99 Bro Split or the $199 Peak Week Protocol textbook — are yours for good, subscription or not. The free members’ library works like the rest of your membership: read everything in-app while your subscription is active.

What is the difference between the standalone and coached editions?

Same program. The coached edition adds inline prompts to run it with SuperTrop, your AI coach — paste your PR sets and it tells you whether you progressed the muscle or just the movement, asks for a replacement when a lift stalls, and scales the nutrition to your bodyweight. The program that answers back.

Who are these programs for?

Intermediate-to-advanced lifters who are done arguing about splits and want a system they can run for years — natural or enhanced. Each program teaches the method first, then lays out every session movement by movement.

How many books are there?

Five titles at launch — the Power Bodybuilding Bro Split, Critical Mass, the original Power Bodybuilding, the subscriber-exclusive Arm & Delt Specialization, and the 453-page Troponin Peak Week Protocol textbook — with more releasing on a rolling basis.

Is this medical advice?

No. Every program is education, not individualized coaching or medical advice. The numbers are published templates a real coach scales to the athlete in front of him.
