Arnold’s self-consciousness about his calves has been well-publicized over the years. They used to be small, so he’d cut the bottoms off his sweatpants while he trained to expose them. This motivated him to improve the area, which he ultimately did by building massive gastroc and soleus muscles. Extreme high-volume and high-training frequency were his keys to bringing up this weak point; but it was even more than that. Arnold seemed to be a bit more cerebral when it came to calf training. Here’s what he had to say in a past issue of Muscle Builder :
In the 1970s, bodybuilding had major publicity thanks to the appearance of Arnold Schwarzenegger , Franco Columbu , Lou Ferrigno , and others in the 1977 docudrama Pumping Iron . By this time, the IFBB dominated the competitive bodybuilding landscape and the Amateur Athletic Union (AAU) took a back seat. The National Physique Committee (NPC) was formed in 1981 by Jim Manion ,  who had just stepped down as chairman of the AAU Physique Committee. The NPC has gone on to become the most successful bodybuilding organization in America, and is the amateur division of the IFBB. The late 1980s and early 1990s saw the decline of AAU-sponsored bodybuilding contests. In 1999, the AAU voted to discontinue its bodybuilding events.
Greene is an avid artist who often creates self-portraits to help himself build and maintain his ideal physique.   In August 2011, he exhibited some of his work to the public; at the exhibition, he stated, "As a professional bodybuilder, I'm a master sculptor. The art show made me realize that I've always been an artist: my medium the human physique. My life is what I make it, just like the art I've produced on canvas and on stage. This art show makes this statement. I'm celebrating some personal accomplishments and my own artistic expression."
