It is said that men usually have more lean than women. I would like to know what does the 'lean muscle mass' mean? is it just the muscle mass? How would you calculate it?
Consider an example, a person X who's weight is say :90 kg.
Then consider another person Y who's weight is also :90 kg.
Both have same weight, BUT, X has more lean mass than Y. What does that mean?
it means your bodyweight is a sum of different factors:
- Your body fat mass (fat percentage)
- Your body muscle(lean) mass (muscle percentage)
- Your body water composition
Lean mass is thus the pure muscle mass without the fat. Men have more lean mass than women , because their body composition and physiology has more muscles, particularly in the upper body. Thus it makes the muscle's percentage higher than the one in women.
To calculate your lean mass you need first to measure your body fat percentage. You can do this using machines (some are not very accurate) or using a caliper. The caliper is the fastest and cheapest tool you can have.
Remember two things:
- you will need some help to take the measurements
- This method is an estimate, always consult a doctor for the best most up to date technique
