I found out this helpful guide on r/flexibility. I’ve only tried the starting to stretch program using the follow along video a few times, but I didn’t do it long enough to notice improvements. It was pretty convenient to do it, though, since you can do it in your own room. Maybe it’ll help you.

I’ve built up a stretching routine over the last few years. My methodology has been trial and error. But the general prices works like this:

First, when I notice that something hurts or is tight, I try to identify the muscles near it. Then I search for dynamic and static stretches that target those muscles and I try to get about three or four.

I add those to my pre workout warmup and/or post workout stretches. After about a week of using them I might realize some aren’t as useful as others or sometimes they’re just redundant. So by a process of elimination I usually only keep one or two.

So over the years I now have a warm up and stretching routine for my hips, shins, knees, neck, back, and shoulders.

I wrote aworkoutaday.com for myself. But it’s free and includes a personalized mobility/flexibility routine, so you might find it useful if you ignore the workout portion. Muscles targets can be adjusted, so if your legs are tight you’d bump up the flexibility targets for quads, hamstrings and the like to adjust the workouts.

I’m still working on exercise progressions, but it should be a good place to get started.
