Hey guys. I'm 19 and trying to bulk up. When I started the bulk up period I was 168 lbs and hoping to get to at least 175-180lbs. I've been trying for a month now. I've been lifting a lot heavier (a lot of 5x5 and 4x6 reps) and training harder. I was eating around 2,000 calories a day, now my calorie intake is between 3,000 and 3,100. The problem is I have been loosing weight. I'm now down to 160lbs. Yes i've gotten a lot stronger and have gained a lot more mass but why am I loosing weight. I'm trying to gain! lol. Any advice or workouts are great. Thanks!
