Idk, if Musk has MA experience - it was definitely a long time ago since the last photo I saw of him was from two years ago in a yacht and he was a fat ass motherfucker

Hopefully all of his challengers have martial arts experience

To be honest, they could beat him on everything else but fight since he's a long time BJJ fighter and a blue belt holder (if I'm not with wrong impression). And getting blue belt not only in BJJ but in any martial arts sport is no joke!
