Okay guys being some what new here to the forums I need to know about LBM! One I'd like to know how it's calculated. Two if I'm unsure rreally about my BF % will this be a huge deal or do I need to get it calculated. And the biggest question is if I want to let's day get to 8% bf and I'm currently at 11%, is the weight calculated from my height 6 foot to the 8% BF the weight I need to get to?
