One of my friends at my home gym is a trainer, and back in April I asked her to measure my body fat %. Using the calipers (pinchy thing).
Last weekend I decided it was time for a follow up, so I snagged her and asked her to measure me again.
This time the gym got a new "fancy" scale that claims it will tell you your body fat %. So I hopped on the scale, and grabbed the handles. It calculated my weight and then spit out my body fat %. Before I tell you what it said, here's a generalized grid of where the percentages fall.
Women (this is an average indication, as many charts take age in to consideration)
Essential Fat 10-12%
It said my body fat percentage was 31%. Ummm, no. Do you see how close that is to obese?
So we went to the caliper method. I won't tell you exactly what it came out to, but let's just say it was a drastic difference. The moral of the story being, don't trust a scale to tell you your body fat percentage because I am concrete proof that they can be very inaccurate.
