Before I get bs I'm an incredibly fit person already - 100 push ups, muscle ups, etc. What I want is tips to reduce waist size.

I'm looking to get to a 30 or 28, so shortcuts or techniques people have had success with at the gym.

I know genetics ( cheers 1% neanderthal genes ) are the main reason white dudes still carry waist fat, however you do get the odd guy who can get cut there.
