Is it alright for someone to focus on their upperbody if it's lagging in both strength and mass, or does one need to squat and deadlift to actually increase the size of their arms, chest, and lats? I know the whole GH release is a fallacy, when it comes to heavy squatting, but some people still argue that squatting will help an individual to increase their overall mass through the systematic overload it causes on the body. What say you all to this, hm? If mass is the only concern, wouldn't pushing up the bench, military presses, dips, pullups, and rows drive upper body mass? Finally, if one needed, say, 4000 calories to add mass at a steady rate while working out the whole body (let's say, using squats and good mornings for legs), wouldn't they need less overall calories to add mass if they stopped training legs, since they'd be using less calories to work the biggest part of the body?
