Circadian Strength

Train with your body's clock, not against it.

Lift the same barbell at 7am and at 5pm and it won't feel like the same bar. This guide explains how body temperature and hormone rhythms shift across the day, then turns it into a simple protocol you can use this week.

What's inside

• The daily temperature curve and what it means for strength
• The hormone cycle: cortisol, testosterone and growth hormone
• How to find your chronotype and shift your training windows
• The four training windows and what to train in each
• A one-page training protocol
• A sample 5–6 day training week
• Daily habits that hold your rhythm steady, plus a quick-reference page

Who it's for

Lifters and gym-goers who want to get more from the same training. General fitness education, not medical advice.
