Anatomy
What's tested
Anatomy questions test function, not trivia: planes of motion, joint actions (flexion/extension, abduction/adduction, internal/external rotation, inversion/eversion), spinal regions, and how breath moves the core. Know the diaphragm's role, the deep core cylinder (transversus abdominis, multifidus, pelvic floor, diaphragm), and key muscles in common poses: psoas and hamstrings in forward folds, glutes and erector spinae in backbends, serratus anterior and rotator cuff in weight-bearing shoulders.
Expect questions on joint safety: knee tracking in Warrior, avoiding dumping into the lumbar spine in backbends, keeping the cervical spine unloaded in shoulder stand, and modifying for osteoporosis (avoid deep flexion and loaded twists), hypermobility (emphasize stability over range), and hypertension (avoid long inversions).
Traps: "no pain, no gain"; stretching ligaments to gain range; cueing "tuck your tailbone" as a universal instruction, which flattens the natural lumbar curve; treating sharp or electric sensation as something to push through, when that is neural rather than muscular. Many items describe a shape and ask which muscle lengthens versus contracts.
Rule of thumb: joints stack, spine follows breath. Worked example: in a forward fold, hinge from the hip crease with a long spine; if hamstrings limit the fold, bend the knees rather than rounding the lumbar spine.
