Some problems with the caliper approach include:
1. Different devices vary in quality and accuracy;
2. Skin conditions such as sweat and dryness affect measurements;
3. Different body types can affect readings.
For example: Sally may have lots of fat in her triceps but the fitness professional does not choose this as one of the areas on which to use a caliper;
2. Testing can be embarrassing; and 3. Some fitness professionals cannot conduct this properly.
