Hi coach, if you want to be really big:
-how much weight gain should you aim per week (1lb/week is reasonable?)? Or you should aim to eat as much as possible?
-How often should you up your calore intake? When the weight gain is lower than expected?
-Do you really need to count your macros? I find it much easier to just count proteins (about 0,8-1,2g per pound of bw) and calories, cause due to my tastes it allows me to have a much wider variety of foods in my diet (some days will be higher in fats and some days will be higher in carbs, but protein will stay anyway in the above range)
