The formula to calculate the Dumbbell Weight (DBW) is:
\[ DBW = BBW - (BBW \times 0.20) \]
where \( DBW \) is the dumbbell weight in pounds, and \( BBW \) is the barbell weight in pounds.
Dumbbell weight refers to the weight of a single dumbbell, which is often calculated as a percentage of the weight of a barbell. This calculation helps in determining the appropriate dumbbell weight for exercises when transitioning from barbell exercises.
Let's assume we have the following value:
Step 1: Multiply the barbell weight by 0.20:
\[ 100 \times 0.20 = 20 \]
Step 2: Subtract this result from the barbell weight:
\[ 100 - 20 = 80 \]
Therefore, the Dumbbell Weight (DBW) is \( DBW = 80 \) lbs.
