Your reason for doing something is your motive. Your motive to go to school every day is to learn. Or maybe the thought of your parents' anger and a run-in with the truant officer is motive enough. The word motive comes from the Latin words motivus, meaning moving, and movere, meaning to move. Think of motive as the thing that moves you to act.
What is the average muscle mass? Muscle mass is important in maintaining a healthy body. Depending  on age and physical activity level, the average muscle mass  percentage lies between 38% and 54% for men a â¦ nd between 28% and 39%  for women.Answered. I don't know the average, but I am 26, and workout 4 times a week doing lots of cardio (an hour or more). I have 24% fat and 38% muscle. I think the average woman is 25- â¦ 30% muscle.
Contrary to what one might think, fatty tissue contains less percentage of water per volume than does muscle tissue. One pound of muscle has more water in it than one pound of fat. So the less lean a person is, the less their body weight is made up of water. In extreme obesity, the percentage of water in the body has been measured to reach as low as 45%. Due to physiology, an average, fit and trim adult woman generally has somewhat more fat tissue than does a man of similar fitness and age.
