Any girls that used to be too skinny but gained weight/got in shape?

I'm and athlete so I got to be big but if you want to bulk up buy those powder work out shakes what they do is put stuff in you that will make you gain weight if you don't work out so do that and work out (mostly run or you will get tone and that's unattractive) or lift weights low amounts but do large reps so like 30 pounds and bench it like 50 times stuff like that and you won't get tone but you will be bigger healthy and stronger.

That happened to my friend. Some people are just naturally very skinny and have high metabolism. I don't know. You can try eating more. And I'm not talking about junk food and greasy crap because that's messing with your health. And if you do gain weight make sure that you consistently do some cardio and weight training so that its lean muscle and not fat.

I used to be super skinny. I didn't get over 100lbs til I was 21 and started taking fertility meds. Then I gained 30lbs and stopped. And, alas, no baby!

Wouldn't advise this as the sudden increase of sooo much weight resulted in MORE health issues than I previously had! So however you end up gaining weight, make sure you don't gain so quickly!
