Your new male client weighs 180 pounds. You measure his body fat and determine it is 26%. What is your client's lean body weight?

To determine a client's lean body weight, you first need to find out the amount of body fat and then subtract that from the total body weight. The body fat percentage indicates how much of the total weight is made up of fat.

In this scenario, your client has a total body weight of 180 pounds and a body fat percentage of 26%. To calculate the weight of the body fat, you multiply the total weight by the body fat percentage:

Body Fat Weight = Total Weight x Body Fat Percentage

Body Fat Weight = 180 pounds x 0.26 = 46.8 pounds

Next, to find the lean body weight, you subtract the body fat weight from the total weight:

Lean Body Weight = Total Weight - Body Fat Weight

Lean Body Weight = 180 pounds - 46.8 pounds = 133.2 pounds

Since lean body weight is typically rounded down to the nearest whole number for simplicity, this rounds to 133 pounds. Thus, the client’s lean body weight is best approximated as 133 pounds, which aligns with the answer provided. This calculation showcases the relationship between total weight, body fat, and lean body mass, essential for understanding body composition in fitness assessments.
