Acromion process at or below origin of latissimus dorsi? Check

Back of hand/thumb no lower than antecubital fossa? Check

Shoe-pedal interface nearly parallel to the ground when at bottom of pedal stroke? Check (well, sort of: it appears that the pedal isn't quite at the furthest point from the saddle, in which case her saddle might be a skosh too high)

Apologies to Salazar Photography for cutting off the photo credit...
