Con Models felt too far away to see clearly, no zoom pan or rotate
By default there are two models, one on the left that emphasizes only contracting (blue) or stretching (red) muscles, all other muscles are transparent. The right model is a plain muscle on bone model. You can change from profile or 3/4 view of either left or right model independently. You can also full screen one model or the other, but even then it is hard to see activated muscles clearly. There is no way to rotate around the models or zoom in and out as they are doing poses. They set it so that the camera would capture the whole body whether lying down or standing up etc so the camera could stay completely stationary making it easy to link the different asanas together. Still, the end result is the models feel way too small and far away to see clearly.
