I've been killing myself I'm the gym.....I've gained 4lbs....help

Muscle?

You will gain for a week or two.....but give it a month before you start weighing....plus muscle weights heavier than fat....so watch what exercises you are doing... a marathon runner is so thin but a sprinter is huge and full of muscle....swimming is great for losing weight without bulking up.....

To much Birthday celebrating??? Inches how are your clothes fitting? Water retention it's hot here in Florida and sometimes that is a reason, Enough protein ? To many wrong carbs. Good Luck and Happy Birthday

"You can't out-train a lousy diet"

It's hard to give you advice with so little information? Have you had fills, do you have restriction, what do you eat, what do you do in the gym, bandster hell?
