Scope: a practical map of the body
The atlas covers the main muscle groups and the basic structures involved in movement. Each record explains where the muscle sits in the body, its main task, which everyday jobs bring it into play and which training movements work it. Memorising Latin terms is not the goal; terms are explained where they appear, but the real aim is to let you answer real questions such as "why does this part of my back get tired?"

You can narrow the records by body region: upper body, lower body, the core. Choose a region and you see the muscles there and how they cooperate with one another, because no muscle works alone. From each muscle record you can go straight to the records in the Exercise Atlas for the movements that target it; the two atlases mirror each other.
How should this knowledge be used?
Knowing what each muscle does brings balance to your training: you notice that you keep working the same region, and you see the regions being neglected. Understanding which muscles a day at a desk shortens also feeds your decisions about ergonomics. In cases of pain and injury this atlas is not a diagnostic tool; for complaints that persist, see a health professional. For the general frame you can look at the Sport and Fitness section.
