Are we talking stretching after a workout to prevent muscle soreness and maintain flexibility (and in the morning to get the cricks out of your joints) or… flexibility training?
I’m assuming the latter, and I’ve heard it very often that, much like strength training, you need to take rest days when doing flexy training. You can incorporate those into your 30 days, though, because it is still part of doing the training!
Also, please be sure that you’re fully warmed up before engaging in flexibility training. Either a super hot bath or shower, or a good warm up at least, to prevent straining muscles and such.
Good luck!
