Last month I had my BF measured (3-point caliper) at the gym. It was 33.9%; I thought it would have been lower than that. My weight was at the time around 134 lbs. I'm 5'4" and about in the middle of the healthy weight range for my height. I'm also fairly muscular since I get plenty of exercise.

According to the charts posted on this thread I'm in the "obese" range or in the "fair-poor" range for my age (50). What gives? The trainer was careful with the calipers and I made sure I did what he said to do as far as the way I held out my arm, etc. Could hydration or workout make a difference? He took the measurements before my workout, and I had only had about 1 liter of fluids so far that day (it was around 10 AM).

I thought that the calipers method was pretty accurate if done right. The trainer is also the owner of the gym and has been for at least the last 8 years. So he should know what he is doing.

Any answers are appreciated!

Thanks

Joan
