In Tyson's main!verse - despite occasionally doing control exercises with Jasmine - Tyson didn't really start meditating until he was taught to by monks whilst the dent in his torso recovered and yoga came afterwards. This applies for almost all verses, except Orphan AU - child!verse, child!verse 2, & teen!verse - and Hogwarts AU where Tyson doesn't have, and isn't going to gain, the dent in his torso.
Tyson isn't going to take up meditation [fully; he's dabbled slightly as a teenager in both AUs] or yoga in any of those verses, but beyond them - an adult Tyson within those universes - he would end up doing both. In his early twenties, Tyson would begin meditating frequently in those verses and by mid-twenties would be doing yoga frequently too. In his main!verse he's decently flexible already, but those version of adult Tyson would be very flexible
