Hi im a24 year old woman and just woundering what weight should i be as im 6 stone and thank u ?

What's your height?: As a starting point for discussing appropriate weight, check out http://www.nhlbi.nih.gov/health/educational/lose_wt/BMI/bmicalc.htm. Of note, this is not the be all & end all. Very muscular athletes will show up as overweight & obese (http://www.menshealth.com/fitness/the-problem-with-BMI). At the opposite extreme, you don't want to be skinny fat either where you're the right weight but all flab.
