How often to strech?

Getting a bit of mixed messages in the video.  Coach mentions to only do the series once a week but also mentions if you need to do more during some stretches.  I need all the help I can get for flexibility so trying to figure out what to do.  Thanks.

What he means is that you do the whole course once a week. My suggestion is to take out your weak links/exercises from the course and work on them a couple of times a week. I do a 1 minute pancake and middle split before I go to bed 3 times a week
