I just had an argument with some guy I know from the gym. He told me he measured his skin folds by caliper.
His measurements: Chest 6mm (0,24 inch) Stomach 20mm (0,79 inch) Leg 8mm (0,315 inch)
I know his weight and his age and so I put this measurements in some online bf-calculator. The bodyfat percentage should be around 10-11%
Optically this guy is at least around 15% plus. You don’t see any separations, nothing. I told him he measured wrong, because such a difference is ridiculous. He said, that all those calculators are rubbish and often people look like 2% bf more than they actually are.
Who is right? I always thought and experienced that a properly done caliper measurement is fairly exact.
Optically? Honestly, unless you happen to be a personal trainer, have been one, or have been a die hard bodybuilding fan for years, I would not expect most people who haven’t been training for several years to be able to visually accurately assess someone’s body fat.
Online calculators are shit.[/quote]
x2. Also, OP, as you said, “a properly done caliper measurement is fairly exact.” That means, someone experienced, doing the caliper measurement accurately, can generally get it within a couple percent. It’s pretty easy to mess up though.
And, as these threads always lead to, who cares what the actual number is anyway? Is he going to say “you may look leaner than me, but my bodyfat percentage is lower according to this caliper reading, so I win!”
