The Formula
In Your Hands.

The Silver Fox Black Book

The app calculates your Target Lock date. The Black Book is where you earn it. Every workout logged, every macro tracked, every habit recorded, every day debriefed — written down because the formula lives on the screen, but the discipline lives in your hands.

Why Physical Matters

There Is Something
A Screen Can
Never Replace.

The Sigma Formula app tracks your score. The Sunday check-in updates your Target Lock. The leaderboard shows you where you stand. Every number, every band, every date — all of it calculated and displayed on a screen.

But the most successful men in The Standard do something else. They write it down.

Not because the app is missing anything. Because writing creates a different kind of commitment. When you put your training log in ink — exercise, sets, reps, weight — it becomes a record. A proof of work. A physical document that says you were here, you did this, and you earned the score you have.

The Black Book is not a backup to the app. It is where the Sigma Formula becomes real.

The formula calculates the date.
The Black Book builds the man.
Inside The Black Book

Seven Sections.
One Complete
90-Day System.

Every page in the Black Book has a job. Nothing is filler. Nothing is decorative. Every section was built to track a specific input that feeds your Sigma Score — or to build the mindset that makes you show up when motivation is gone.

Page 1Dream List
Write down every hope, wish, and dream you want to see come true as a result of running this formula. The man who writes his dreams down is twice as likely to pursue them.

What's Inside

Every Section.
Every Purpose.

01
Dream List

Write down every hope, wish, and dream you want to see come true as a result of running this formula. Not goals. Dreams. The man who writes his dreams down before the work begins fights harder when the work gets difficult.

02
4-Week Goals + Reasons + Transforming Patterns of Action

Three specific goals. Three reasons they matter. Then — the old patterns that have been holding you back, written directly beside the new patterns that will replace them. This is where the Sigma Formula changes behaviour, not just the body.

03
90-Day Habit TrackerFeeds: Sleep · Stress · Supplementation pillars

A 90-row grid that tracks any habit across the full program. Sleep hours. Protein target hit. Workout completed. Steps. Supplements taken. The grid is the visual proof of MOTT — Most Of The Time. Hit your habits 75% of the time and the formula works. Hit them 90% of the time and it works fast. Miss a day, mark it honestly, keep going. The Black Book doesn't reward perfection. It rewards the man who keeps showing up.

04
Beginning of Day Briefing

Every morning: three action items you will complete today that move you toward your goals. Two ways you will support and encourage someone else. This is the Universal Law of Reciprocation — built into a daily ritual. The man who gives gets back.

05
End of Day Debriefing

Every evening: progress on your three action items. Two things you did today to support others. Three things you did well — and three things to do better tomorrow. The debrief closes the loop. It is the difference between a day that happened and a day you ran.

06
Training LogFeeds: Workout pillar

Date, day of week, bodyweight, and training time at the top. Ten exercises per session. Sets one through five. Reps and weight recorded for every set. The complete physical record of every session you will ever do on this formula.

07
Nutrition LogFeeds: Nutrition pillar

Daily macro goals at the top — fat, carbs, protein, calories. Every meal tracked row by row. Daily totals calculated against targets. Supplements and vitamins logged at the bottom. Your nutrition pillar has always been the most undertracked. Not anymore.

Ritual.The Secret Inside The Black Book

Most training journals are tracking tools. You write numbers down and move on. The Black Book is something different. The briefing and debriefing pages don't track your training — they track you. Three things to do today. Progress on those three things tonight. The Universal Law of Reciprocation — built into every single day.

A man who fills in the debrief honestly every evening for 90 days doesn't just change his body. He changes how he thinks about effort, accountability, and what he owes himself. That is what makes the Black Book different from every other journal you have ever owned and stopped using by week three.

The Sigma Formula gives you the prescription. The Black Book makes you take it.

"The men who track their nutrition aren't smarter than the men who don't. They just know something the others don't — that the numbers are the only honest conversation your body can have with you."

"I've bought journals before. Nice covers, blank pages, never made it past week two. The Black Book is different because it tells you exactly what to write. The briefing and debriefing is what did it for me. I haven't missed a day in 67 days. That's never happened in my life."
