Doesn’t look like the “fitness life” paid well.
Looks like a normal house to me...Getbig has high standards.

The average Getbigger would rather spend a million dollars on a nice car, house, boats...

Personally, I'd rather see that cash invested in something that pays a secure 5% per year. Under that model, you can buy the nice things if you want, without being bogged down in debt. Frankly, for me personally, I'd rather just know I don't need to work a 9 to 5, and then can't be cancelled by the PC mob, etc.
Regarding what you are saying though, the fitness life in general does not pay all that well. I think Greg Plitt said he was making $2 million per year. When he died, he had something like $800,000 in the bank. But I feel like he was the exception.
Mike O'Hearn did very well too - and to stay at the top of the fitness industry for as long as he did is unprecedented.
