A useful channel with lots of videos that combine mobility training with pilates. This might be contentious, yoga aren't particularly good at increasing your flexibility but it is great for overall maintenance. To gain flexibility and strength in your range of motion we must look toward mobility training. Mobility = flexibility + strength. Then we have pilates which do add a degree of strength challenge and body control, together with mobility movements they make a good pair. I find this channel youtube.com/@MarieSteffen to have many good videos for that purpose, helping you to improve on yourself and gain more mobility. The instructor is nice and clear in her demonstrations (okay the music choices in the videos doesn't suit me, eh) so its easy to follow along.
Adding another link that combines pilates strength and mobility work as example of her workouts: youtube.com/watch?v=kvpC2eOTUw…
