I just saw him working out at my gym, World's in Burbank, Ca and he has a full head of hair! It was surreal because the gym was crowded and I was the only one to go up to him and say hi or even look at him. LA people are jaded about seeing celebrities or maybe no one knows who he is.
His legs are still huge but in a t shirt he looked a little smaller than I expected but still 3 times as big as anyone else there. I only saw the end of his leg workout. He did lying and standing leg curls and then standing calf raises. He didn't go heavy and rested at least 3 minutes between sets, nothing exceptional like in his videos.
