Before I begin to try and lose X amount of lbs for my summer comp, I want to have an idea of how much body fat I'm carrying around. I had a skinfold done about 3 years ago. I've changed quite a bit since then, maintaining +/- 10lbs but became noticeably leaner in appearance. Having to go off a mirror isn't something I want to rely on though. I don't know if I have 25lbs of fat to lose. Recommendations?
