In my opinion, it all varies from person to person. We at this board have been (and will always be) searching for that program/regimen that will keep us big and ripped. Our body-types are different. We need different foods, different ratios of macronutrients, different sleep cycles, different workout programs, different post workout nutrition, etc.
Myself for example:
Endo/Meso (loosely speaking)
Optimal Diet: 20 carbs, 40 protein, 40 fat (20/40/40)
Optimal Weight Routine: HIT Style Full Body w/ a few intensifiers (ex. dropsets, supersets, whatever) to be performed M/W/F
Optimal workout configuration: 15 minutes warmup/45 minutes weights/10 minutes abs/20 minutes moderate-low intensity cardio
Non-Resistance Days: 45-60 minutes cardio at a moderate intensity
Post-Workout Nutrition: 30 grams hydrolyzed whey/casein providing full spectrum EAAs immediately post workout and a whey isolate/flaxseed shake 30 minutes after that.
It all varies......... I'm still tweeking things...
