Since January, I've been on a successful bulk doing 2800 cals/day. Some may say that's too low for a 6'3" guy but it worked since I've been pretty sedentary. However, that's changed recently, when I fairly drastically increased conditioning intensity. My plan has been gaining about 2 lbs a month, ending up at 210 lbs at the end of the year. Right now, I'm 189 lbs and I actually dropped to that from 190.7 lbs over the last 2-3 weeks.
By how much should I increase my cals to get back into bulking without overshooting it too much as well as not wasting any more weeks crawling up by like +100 cals/week? What's a reasonable amount?
Although doing a bigger bump would catch me up to the plan, I want to avoid unnecessary fat.
BONUS QUESTION, since I'm already here, what macro split would you recommend? Right now I'm doing 210P, 350C, 62F. Any point in pushing the protein further up with increased calories? How about fat? Keep it low, up it somewhat? I already tend to under-eat carbs by like 50g in favor of fat.
