Maximum Bicep Size Calculator

Formula

To calculate the Maximum Bicep Size (MBS):

\[ MBS = WS \times 2.5 \times LF \]

Where:

\(MBS\) is the maximum bicep size (inches)
\(WS\) is the wrist size (inches)
\(LF\) is the lean factor, calculated as \(\frac{100 - \text{Body Fat Percentage}}{100}\)

What is Maximum Bicep Size?

Maximum bicep size is an estimate of the largest circumference your biceps can achieve based on your wrist size and body fat percentage. It is a theoretical value used by bodybuilders and fitness enthusiasts to set goals and expectations for muscle growth. It is important to note that genetic factors also play a significant role in muscle development and may affect the actual maximum size achievable.

Example Calculation 1

Let's assume the following values:

Wrist Size (\(WS\)) = 7 inches
Body Fat Percentage = 15%

Using the formula:

\[ MBS = 7 \times 2.5 \times \frac{100 - 15}{100} = 14.88 \text{ inches} \]

The maximum bicep size is 14.88 inches.

Example Calculation 2

Let's assume the following values:

Wrist Size (\(WS\)) = 6.5 inches
Body Fat Percentage = 10%

Using the formula:

\[ MBS = 6.5 \times 2.5 \times \frac{100 - 10}{100} = 14.63 \text{ inches} \]

The maximum bicep size is 14.63 inches.
