Pro Color coding provides helpful cues
Color coded stretch and contracting muscle model (left) helps understand how to perform Asanas to get the benefit of the pose by doing it properly.
Pro Useful for actually doing or planning a yoga routine
You can create your own custom playlist or use a pre made playlist. Surprisingly effective for those who have a basic understanding of core concepts in body posture, movement and breathing in asanas.
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.
Con No text or labels for muscles in use
There is no text or labels about what muscles are being contracted or stretching in asanas (poses), and no way to select individual muscles.
Con Indian/Sanskrit names for poses not included
This would be expected for students of yoga, that it's not included seems like a glaring omission.
