Actually, funny you should say that. Most sources say in his prime he was around 145 (keep in mind that Bruce Lee was about 5’6”, whereas Tiger is 6’1” and weighs around 185lbs), though during heavy weight training he had gotten up to around 165lbs at one point. Given the comments in this thread, it seems people think Lee putting on 20-30 pounds of muscle would have been impossible, as that’s essentially what Tiger has done.
I’m sorry, but Bruce Lee was not good in the same way that Norris, Segal, or any of those other guys are good. I don’t want to turn this into a Bruce Lee vs. The World thread, but Bruce Lee was simply one of the quickest fighters in the world, if not the quickest. He would have wiped the floor with almost anyone. And this is coming from someone with deep respect for Segal’s fighting ability, as I trained for years in aikido (Segal’s chosen art).
