I eat 5-6 times a day work out religously and rest well. I do nothing but powerlifting train bench heavy once, light once per week. Legs once and back once per week.
Gains are coming, that is key.
We all can not gain weight easily and in the big picture, it is a blessing. Gaining weight easily may eventually catch up to easy gainers when they stop training hard and do not modify their diets, they will get fat. Be patient and continue on your course. You cannot get too much stronger and not get bigger. Quality bigger is also important.
