Are they not allowed to relax?
You only see this shit in modern open bodybuilding, abs spreading apart, watery/bloated stomachs yet shredded glutes, distended stomachs. A lean muscular body the stomach should be shredded flexed, relaxed, exhaling, full of carbs, full of water. These guys are perfect examples of how a lean muscular body looks like, whatever the fuck these open bodybuilders are doing the look is terrible.
