Inside the book

What you will discover.

  1. 01

    The three levers of growth

    Get more leads, book more of them, and close more of the ones who show. Every stuck gym is stuck on one of the three.

  2. 02

    Why more leads will not fix a broken sales process

    The funnel is checked in order: close rate, show rate, booking, then volume. Pouring leads on a leaky close just leaks faster.

  3. 03

    When it is time to invest in paid marketing

    Ads scale a funnel that already holds its floors. The book shows you the numbers that say go and the ones that say fix first.

  4. 04

    The messaging framework that attracts the right members

    Your member is the hero and the gym is the guide. Busy professionals, beginners, and comeback stories, not competition athletes.

  5. 05

    A predictable system that turns prospects into long term members

    Answer in seconds, book the intro, run the same close every time, and keep the feed and follow up alive without the owner doing it all.

Who wrote it

Written by owners, not observers.

Every page was earned inside real gyms. Both authors built and ran their own, then built LASSO to run the same system for hundreds more.

Sherman Merricks

Co Founder, LASSO

Built Dynasty CrossFit from his garage and ran it for 13 years. He owned every seat in the building: coach, salesperson, janitor, and CEO. The sales system in this book is the one he ran on his own floor.

Blake Ruff

Co Founder, LASSO

Built the paid ads engine behind hundreds of gym growth stories. He turned what worked into a repeatable marketing system, and this book is that system written down.
