Ever get done with some higher rep training and say, damn I wish I looked like this cold? So what's the difference? an extra 10 lbs muscle, 20 lbs extra muscle maybe that you would have to gain to look like that? I gain almost an inch on my arms with like one isolation exercise after my compounds, and my chest and shoulders and back look huge. My legs depending on what I do, if it's more reps tend to hold the fullness more for a couple days.
