1. You need a body fat calculator. Thats the most accurate way. Theres a way to do it by pinching and measuring certain spots on your body as well, you can google the measurements for that Realistically, you should buy a measure, they're useful to have if your planning a diet/workout regiment.
2. You can measure body fat with callipers which you can purchase on-line (Accu-Measure). Basically when you subtract the pounds of fat from your total body weight the remaining weight is your 'lean body mass'. This is made up of muscle, bones and your vital organs. But it's hard to calculate just how much muscle you have unless you have a DEXA scan.
