The size of your wrist can be used to estimate the size of your arm. This relationship is often used in fitness and bodybuilding to gauge muscle potential. The general formula is:
\[ \text{Arm Size} = \text{Wrist Size} \times 2.5 \]
Consider a wrist size of 7 inches:
Using the formula:
\[ \text{Arm Size} = 7 \times 2.5 = 17.5 \text{ inches} \]
This means the estimated arm size is 17.5 inches.
