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 :
My point is, even in the 70′s they were doing the same thing, now it’s an app on your phone.
My point is, without drugs we are only going to get so big, and we must realize this, accept this. If the lifter wants to enhance beyond their size limit, they can read Clarence Bass’s “Ripped” and stay smaller but ripped. This takes great discipline; or they will go to PEDs. Folk’s, don’t go to PEDs. This will become your life, funneling your money and thoughts into “your cycle”. You become a druggie. All so you can carry extra muscle on your frame; only while you are on those drugs and for a short time afterward. May God bless your endeavors! -CD
The most common estimation of IBW is by the Devine formula; other models exist and have been noted to give similar results.  Other methods used in estimating the ideal body weight are body mass index and the Hamwi method. The IBW is not the perfect fat measurement as it does not show the fat or muscle percentage in one's body. For example, Athlete's results show that they are overweight when they are actually very fit and healthy. Machines like the dual-energy X-ray absorptiometry (DXA) can accurately measure the percentage and weight of (fat, muscle, bone) in a body.
