1. Under 10%. I am 6'-4" and got a 6 pack recently so I know haha. I weigh about 155 btw.
2. I find I need to be down in the 6-7% area for that.
3. Well, the lower it is, the more cut and ripped he will look. I would say, to stay healthy and look good, between 5 and 12 percent.
4. definitely under 10%
