LeBron James -- Yoga Master ... Says College BBall Star

Add Yoga to the list of things Lebron James does better than everyone else ... that's according to a big time college basketball star who tells TMZ Sports LBJ is the king ... of the downward facing dog.

We spoke to Isaiah Taylor -- a bball star from the University of Texas -- that was present when Bronny led an impromptu Yoga session at NIke's Basketball Academy in L.A. a couple weeks back.

Check out the clip -- Isaiah talks all about the experience ... but when we ask about LeBron's skills on the mat Taylor makes it plain ... the 6'8" man gots some twist game.

Namaste.
