I'm 5'7 and 106 lbs could I join the army or airforce reserves?

I'm having such a tough time gaining weight, stuffing my face as much as I can with food that has carbs and protein along with working out with weights every other day.

I heard you have to weigh between a certain amount, would I be able to get in?

I suggest you join the AF.. trust me.
