Not many fighters are ripped like this guy, but need to see a relaxed pose to judge. He is either pumped or sweat covered.
U don't need to do bodybuilding to get this physic, if u are a cross training athlete. I'd say about 3 times a week focusing compound movements is enough, recommended. If u do more or do bodybuilding type workouts like isolations, u lose the explosiveness. And they should already have explosive training with weights covered. That's a lot commitment.
