i have never worried about my macro nutrient breakdown. I eat 3 full meals a day. I was skinny growing up, so it was always a challange to gain weight. in years past, I have turned to the gallon of milk a day thing, shots of olive oil, etc.
Every meal has meat in it. protein shakes after training. I always eat till I am full and then some every meal. If I'm hungry I eat. I try not to eat just pure junk, and it has served me well, I ever got too fat.
silver dan made a good point. when you squat/bench/pull, fill your belly up with air. it creates an airbag, so to speak, that stabalizes your midsection. your core (i hate that term) is longer then the average person, so its even more of a weakpoint for you. you have to make it ridiculously strong. that includes your whole back, like he said. look at any really strong powerlifter, the have big, strong, backs.
I think Wendler said it, or something to the effect... "is your back strong?"
- "yea its pretty strong"
- " no its not, its weak. why? because your not lifting as much as you want to."
your weak, I'm weak, and we always will be. get everything stronger.
