Yes everyone has a genetic gift of some sort. I have tiny joints great for bodybuilding not so much for powerlifting. My legs are genetically lean and hold a good bit of muscle even when not worked. However my true gift is the calves. I have no need to work them. I do sometimes just to do it but when it comes to calves I can walk up and beat most people's calves without training them at all. They stay 17 inches andeven when not trained. Considering my knee is only 13.75 inches around at the biggest point makes them look huge. However I won't ever have the Holy Crap tree trunk legs that you do. But with my tiny knees i only need about a 25.5-26 inch thigh for them to look huge so one more inch!!!!
