THE FOUR
MODULES
Start with the free Foundations module. Unlock the full stack when you're ready to move on.
— Evidence-first
Every claim in the LeanScience curriculum links back to a primary peer-reviewed study. If a protocol isn't published in a journal like Med Sci Sports Exerc or J Int Soc Sports Nutr, it doesn't make the cut.
— Progressive design
The modules build on each other. Foundations sets the calorie-deficit and full-body baseline. Metabolic Conditioning stacks Zone 2 and HIIT on top. Advanced Strength unlocks true body recomposition with periodised overload. The Nutrition Lab underpins all three.
— Real training
Seventy-plus exercises with named form cues, sets, reps, and rest intervals — plus video walkthroughs so you can copy every movement on the gym floor without guesswork.
