Q: how to know if i am overweight

A: Medical definition of overweight is having BMI of 25-30 (above 30 is considered obese. You can find your BMI here. BMI measure is far from perfect because it does not take into account the fact that some people are naturally muscular or big-boned which means that they may be heavy, but not overweight. I also feel that the lower healthy BMI limit is set too low for most people. But if you are of average build and do not have a lot of weightlifting experience, the BMI calculator is a good starting point for you to figure out whether you are overweight or not.
