Bubble Guts is a term we hear all the time in modern bodybuilding. Bubble Gut is a real condition that many attach to drug abuse e.g growth hormone and insulin but that may not always be the case. Gut distension can be the result of digestive slowing, which happens when bodybuilders use diuretics and then carb-load while dehydrated. Strong hard abs also make it harder to have a small waist. And today’s bodybuilders are more massive than ever.
