What is the best way to gain weight?

What are you gaining weight for?

Well my body. I'm skinny. I weight like atleat 103 pounds around there and I'm 17 about to be 18 years old . My prom is soon and ugh I want to gain weight . How can I?

If you looking to gain a few pounds try working out a little bit if you don't and more if you do. Which area of your body are you looking to put the weight on. If you are specific I can help you by telling what kind of exercises you are going to have to do to make it work effectively

Maybe trying to eat a little more, if your not eating enough you won't get bigger

Your best solution would be to start gaining some muscle, and feeding that muscle with protein as much as possible. You don't want to put on too much fat by just eating junk. Try weight bearing exercises for large muscle goups, like lunges, pushups, crunches, and feed the muscles you are building with lean protein, not junk!!
