A LEARNING PATH
What is the smallest useful starting point?

Compare time, effort, movement skills and the outcome a study actually measured.
The directory distinguishes free lessons from the 12 Strength Foundations previews. Preview lessons include the first chapter; the remaining chapters, self-checks and complete notes are part of the US$4.99 one-time pack.

Controlled trial; sedentary men; 12 weeks. SIT n=9, continuous n=10, control n=6.
Minutes per session, including warm-up and cool-down
VO₂peak increased by 19% in both exercise groups.
Small, specific trial. Time efficiency does not establish equal safety, enjoyment, adherence or lifespan benefit.

Gillen et al. · PLOS ONE · 2016BUILD AN EXAMPLE WEEK
Change this fictional example to see how mixed-intensity minutes add up. It does not assess your health or calculate fat loss or lifespan benefits.
90 + 2 × 30 = 150 moderate-equivalent minutes / week
Aerobic example reaches the 150-minute reference; the strength example is 1 day and remains a separate component.
Adult public-health reference: at least 150 moderate or 75 vigorous aerobic minutes, or an equivalent combination, plus muscle strengthening involving the major muscle groups on at least two days. Activity below the reference can help; the reference is not a benefit ceiling. This example only explains counting. It cannot check intensity, muscle-group coverage or individual suitability.
