i wouldn't say i have good natural genetics. meaning doing nothing and looking athletic like a lot of my friends did when i was a kid.
but give me some juice, good diet and train 3-4 days a week and I turned into looking like a bodybuilder pretty easily.
now take one of those components away , say juice.. i look athletic and muscular but just smaller and not as round and full.
155lbs vs say 20-25 lbs heavier with the same low body fat .
at this point i been doing it so long continuously... i can take a month or 2 off
the gym and eat a half ass diet and stay at say 75%. if i tighten my diet up totally and train 3 days a week i can maintain
175 lbs at say 7 % bf year round which i normally do .. which at any point i could be ready for a show in less than a month.
i think the key to getting the results you want is first getting ripped, no matter what, then you add the size and you can stay lean.
for many years i did like everyone else , which is backwards. then about 6 years ago i learned the right way.
unless you are trying to be mr olympia , i see no reason to ever get big and puffy. lean always looks 10x better
