How tall is Kai Greene

American bodybuilder and actor.

I’m 5’ 8". I competed with the WNBF at different bodyweights. As a teenager I competed at 212 for my first outing at the World Championships. Five months later I was able to come back at 220 and win the Pro US Cup. The next year I was able to come back considerably heavier. Ultimately the heaviest I’ve peaked at is 230-232.
