Each available class is offered in two versions, the full & short.
The full version of a video class is essentially the entire live class. This includes the full warm-up, flow routine & meditation.
The short version of a video class tends to be around 20 minutes in length and is entirely routine; no meditation. These are great if you are short on time, or working up to the full Qi Gong class.
Please note that the q&a sessions are not included in either version.
