Each individual includes a "unique" physique and muscle density underneath what fat we have. The less amount of fat we've the more we notice certain features. If I am 5' 5" and weigh a normal 155lbs, I am most likely not likely to resemble a 6'6" 250lbs NFL linebacker, however I am planning to look awesome for my body system type. So what I am getting at is that, each of us can truly maximize what much of our potential might be with regards to a physical being.
