Didn't he get caught because his prints were all over the steroids he shipped, and he included the gym as the return address .
Smart like a box of rocks.
Hahaha - yes, sorry - I stand corrected
Still, my personal opinion is that it can be pretty hard to make a real living out of a big gym as a solo enterprise - at least it used to be. Even if you negotiate a close to zero lease, the business rates (UK) and utility bills to heat a nice airy space are hefty - industrial units are rarely class A energy efficient (he says based on zero knowledge!

). And you need multiple employees so you're not working all hours. So without 'invisible customers' going through the books as extra revenue from side-deals, if he is playing it straight then best of luck
More likely he's shifted the whole thing sideways and will still be cleaning the money via the front door, no?
