"Bulking" for the first time
I'm 6' 5" weighing in at 205lbs and I'm looking to put on about 10 or 15lbs of muscle. I'm fairly athletic and work out 4 days a week at about two and a half hours per session. I'm consuming 4000 "healthy" calories per day lots of protein and good carbs. Any pointers out there on gaining some solid muscle?
