You might look at body mass index or "BMI" as well. There are some problems with the general guideline that a BMI of 18-25 is "healthy" and BMI of 25-30 is "overweight".

BMI= 26 or maybe even 27 is not unreasonable for a muscular athlete.

Statistically though, a BMI greater than 30, "obese" is associated with long term health problems with lots of different organ systems.

If you are really big figure out what your weight would have to be for your BMI to be 29.9 and make that target weight your first goal. Getting to that number will put years back on your life expectancy.

FWIW I record BMI on 6-10 patients every day. BMI = 18 or 19 is pretty darn thin if you ask me. Something like 21-26 looks pretty normal to me, perhaps in a hotter climate I might adjust my range down somewhat.

Tons of online calculators at google under "BMI calculator," pick a web server near you.
