Question

Answer 1

Answer:

About 40% of your body because 75% of your body is with water.

Answer 2

Answer: About 40%

Explanation:

You didn't specify who you wanted the “average muscle percentage” for. Here are some averages for various adults that are of a normal weight.

Women that don't exercise, have fairly sedentary lifestyles have an average of about 24% of their weight in muscle. With a moderately active lifestyle it can go up to around 30%. High amounts of muscle, such as a weight lifter, can be as high as 35% of weight. Anything over 35% is considered extremely high, typical of competitive bodybuilders.
