How much am i suppose to weigh to have a lean body
male 5'7 weigh 165
You are in the right bracket as the height to weight ratio chart indicates that your weight range should fall between 135 and 167. Nonetheless, your weight is on the heavy side as the target weight is 151. You are safe though. To view the chart, visit http://www.disabled-world.com/artman/publish/height_weight.shtml.
Based on your weight and height, I'd say you're about lean. But hey, ten pounds off wouldn't hurt as you seem healthy.
depends on muscle mass but considering your height id say you probably are right now
