Hi,
First, thanks for all the awesome content and for answering questions like this!
I’ve been lifting for around two years now and have seen lots of great progress. I’m stronger and more muscular than I’ve ever been, but I still have a long way to go towards my goals. Now that I’m seeing more muscle definition, I’ve noticed something strange about my muscle development - some of my muscles seem to have developed really quickly (forearms, calves, and quads), while other muscles seem to be lagging behind (biceps, delts, and hamstrings). For reference, the last few programs I’ve done have been ‘Hypertrophy I’ and ‘General Strength & Conditioning I.’
It’s especially strange since I haven’t done anything to target my forearms or calves, but they seem to have developed faster than anything else (my forearms are almost the same size and my upper arms). Some of this seems to be because my brachioradialis and gastrocnemius attach pretty close to the joints, making them ‘bunch’ and appear larger. Meanwhile, my biceps and delts (and hamstrings) seem to lay pretty close to the bone. I’ve been trying to target my biceps and delts, and they don’t seem to be developing much at all.
How much of this is genetics and something I’ll just have to live with, and how much can I hope to overcome through extra/targeted training? Thanks!
