Last year I started bulking up because I was 58kgs and 186-187cm. Today I weight 73kgs. Even though I go to gym between 3 and 4 times per week, having sessions between 50 minutes and 1 hour and 30 minutes I can see that my stomach got bigger (it's not huge but it's noticeable, before it was flat).
Since the start of this year I don't eat anymore fast-food, also I have a month or so in which I haven't eat much sugar or drink soda at all.
My question is - what can I try in order to become flat again?
Thanks for your time!
