About AnatomyScope
AnatomyScope is a free 3D muscle explorer for lifters, coaches and students. Pick an exercise and the muscles it trains light up on a 3D body you can rotate on your phone, with no sign-up and no app to install.
How exercises are mapped to muscles
Each exercise lists primary muscles (the prime movers that do most of the work) and secondary muscles (synergists and stabilisers). The classification follows the general consensus used in strength-training references such as the ExRx.net exercise directory. Real muscle activation changes with grip, stance, range of motion, load and individual anatomy, so treat the map as a guide rather than a measurement.
Origins, insertions and actions are summarised from standard anatomy texts, primarily OpenStax Anatomy and Physiology 2e (chapter 11, the muscular system).
