Try something like Mysore Ashtanga yoga. It can be difficult but it's never boring if you are doing it right. It hits everything, strength, flexibility, balance, breathing, concentration, every muscle group. And you learn and do the routine on your own rather than a group, except once a week. All you need is a mat and you feel brilliant afterward. Might be hard to get started with covid but check it out once the studios start up again.

Genuine question, not trying to be sardonic: Why is that not boring?

It's a specific sequence of dozens of poses, each different, each with countless aspects you learn and work on. There's so much going on, if you are actually trying to do it right, that there's no cycles left for your mind to wander.

Examples are the angle which you hold your arms and legs; the location of your center of gravity; keeping your knee behind your toes; direction of your gaze, engagement of stomach and perenium muscles; reaching as far as you can in extended poses; balance; remembering the name of the pose; synchronizing the breath with the movement; keeping the breath smooth and slow; learning your body's limits; working with pain; how to hold your hands; the list goes on. And it all works together in an integrated fashion to leave no stone unturned in your body.
