Alternative ways to calculate your Body Frame size

One way of finding how much weight you would benefit from losing in your diet and exercise plan is to use your body size. Have you ever heard people say they are big boned? Well this is what they mean:- Some people have neat little narrow frames, while others have a more rangy skeleton.
So bone mass and muscle mass all play a part in deciding your ideal weight. This is why ideal weight charts have a range of weights that are ideal for your height.

There are two simple methods of determining your frame size:-

  • Measuring the circumference of your wrist, which is by far the easiest.
  • Measuring the breadth of your elbow, which is a bit harder to do but gives better accuracy.
