Yes, they are a machine you stand barefoot on and hold these two rods with your hands. You also enter in your age and height.
Thanks for the opinions guys. I guess 7-8 percent is a fair assumption?
LOL don't be bummed out. Ha 7-8 percent is crazy lean and you won't find many people that can walk around like that for any length of time. Besides 3 percent would be very unhealthy to maintian for long peroids of time.
Well the general consensus is that men have to be at 10% for to have a visible 6-pack, which you clearly have. I'd say you're in the 8% range, which is excellent BTW. 3% would be dangerous.
Those electrical testing machines will give you crazy results sometimes. You can buy a hand held one off of Amazon for like $30. If you use it at the same time every day you will get consistant results.
Keep doing what you're doing, because the results speak for themselves.
