Scales or the clamp thing?
I got by body fat percentage done at the doctors a couple of weeks ago with scales. I'm not sure how it works but it came out as 30% but then today I signed up to a gym and they used a clamp thing pinching fat from my stomach, hips, arms, thighs and calves and it come out as 17%
The two measurements are very different so you can see why I'm confused. Which one is correct?
