Muscle circumference measurements are considered a crude and difficult-to-interpret method for estimating hypertrophy because they cannot differentiate between actual muscle mass, adipose tissue, and intracellular fluids. This limitation means that changes in limb girth may reflect fat storage or water retention rather than true skeletal muscle growth, potentially leading to inaccurate conclusions about training effectiveness.
