Weight Gain struggle
So I've always had a problem gaining weight since I was little. I'm 5'4" 100 lbs on a good day but I've been trying to get at least up to 110 but no matter what I do, I've been having lots of bread, multiple big snacks throughout the day (crackers, sandwiches, soup) but I just can't get over 100 consistently. I've done light workouts since I'm trying to bulk a little too but I just don't know what else to do. Maybe it's just fast metabolism or something cause even in school I ate like shit and didn't do any physical activity but I was still like 99-100. I'm really out of ideas, if anyone has advice I'd appreciate it.
