90-Day Body & Mind Transformation

This is not a diet.
It's discipline in motion.

Ninety days. Four phases. Twenty-one laws. The book gives you the system — the companion app runs it with you, every single day.

By Dylan C. Herlehy · Paperback & Kindle

Four phases. One system.

Days 1–7

The Reset

Shock the body. Reclaim the mind. Fruit, raw nuts, raw vegetables — nothing that ever had an ad campaign.

Days 8–30

The Control

Clean fuel returns. Lean days, refeed days, strength and sprints. Routine becomes instinct.

Days 31–60

The Discipline

The plan is law. Full split, sprint progression, advanced recovery. You're not trying — you're operating.

Days 61–90

The Purpose

Clean refeeds, stillness practice, and the Teach-One Rule. Discipline becomes identity.

The book sets the law. The app keeps it.

A live fasting clock

Hours fasted, when your window opens and closes, and what to do right now.

Today's orders

Your training and your fuel for this exact day of the program — pulled straight from the guide.

The discipline wall

Ninety squares. Every law you keep fills one in. Miss a day and you reset forward — no restarts.

Day 90 reckoning

Your Day 0 numbers and purpose statement, read back to you beside who you became.

Start the 90 days.
