Inside the playbook

What you'll actually get.

The framework

  • The three-lift structure that builds real strength in three 40-minute sessions a week
  • Why cardio isn't the priority after 40, and what to do instead with the time you'd have spent on the treadmill
  • How to progressive-overload without a coach, a spreadsheet obsession, or guesswork
  • The warning signs that mean modify the lift, not the signs that mean quit lifting

The equipment list

  • The exact home setup for under $300 if your gym membership isn't happening this year
  • What a 5am gym session actually requires the night before, packed bag and all
  • The one piece of equipment worth buying before any other, and the two to skip
  • How to structure the 40-minute session so warmup, lifts, and mobility all fit
Kathryn Crosby, founder of Build Your Protocol
Why I wrote this

I lift at 5am because the rest of the day refuses to cooperate.

Four kids, a consulting company, and a body that started losing muscle the moment I stopped paying attention to it — that's the math that got me into the gym before sunrise. I didn't have time for a program built for someone with two free hours a day. I built a three-lift structure that fits in 40 minutes, three times a week, and actually builds strength instead of just burning a session. This is that structure, written down.

Honest answers

Things you're probably wondering.

Is this medical advice?

No. None of it is. I'm not a trainer or a physical therapist. If you have an injury or a diagnosed condition, get cleared by a professional before starting any new lifting program.

How long until I see results?

Most readers feel a strength difference in two to three weeks and see visible change by week eight, following the program three times a week as written.

Will I have to buy expensive equipment?

No. The playbook works with a commercial gym membership or a sub-$300 home setup. Chapter three covers both paths.

Can I upgrade to a bigger playbook later?

Yes. At checkout you can add the parent playbook, Build Your Protocol ($79), or the full Library Bundle ($179) in one click. After purchase, you can buy additional playbooks at full price on the Library page anytime.

What's the refund policy?

There is none. All sales final. That's why Chapter 1 is free — so you can sample the method before you spend a dollar.

Who is this not for?

Women who already have a lifting program that's working. Women looking for a two-hour daily gym ritual. Women who want cardio-first programming.

One $29 playbook. Three lifts a week. Strength that actually compounds.
