The UFC pay for all travel expenses. Training is normally around 10% of the purse. There not starving.
stop making statements like they are fact, you have no idea what you are talking about.
Just your agent or manager takes 10% way before your training fees if your gym is not your manager. Then you have all sorts of other expenses which hopefully get covered by sponsors so that what you get paid is what you get to keep.
The top level guys obviously get much bigger sponsorships or PPV%.
The reason we know JDS made way more than 400K is the NIKE sponsorship as he is one of the select few who have that deal which was brokered by the UFC.
