I keep a log of my measurements over time, cals etc. Looking over it though, I see a pattern that I really can’t explain. My arms don’t seem to respond much to training, with direct arm work or just the big lifts.
Yet, the only times they do grow are during hypocaloric periods. I added half an inch to my arms the last time I went on a diet, which makes absolutely no sense. Anyone ever experience a similar result or have an explanation?
