Yes, the character is definitely doing Tai Chi in the movie, as far as I remember when I saw it last.
Thanks! I now see that Tai Chi is mentioned frequently online in context of the film unlike yoga so that should be right; it narrows things down.
Off topic but it looks like a still from a bowling windup
I think it’s just something they did for the movie. Seems similar enough to yoga or taekwondo for viewers to infer that the character has discipline or whatever without actually making them be into something like yoga or taekwondo.
