Well, I'm not a doctor or anything. It's your joints. But I wouldn't do it if I wasn't down to almost no body fat.
And elite athletes are down to around 3% body fat. I talked to Chad Hennings about it once (he was speaking to a group and talking about his atheletic training with the Dallas Cowboys). 8% is closer to a non-athelete who is slim but not annorexic.
So, I stand by what I said. But its your life.
