go from 130 lbs to 150lbs

Hi I'm new here today and I actually want to add 20 lbs which is tough for me. I have very thin arms and legs and carry a little extra weight in my stomach. I guess I zoomed in on my profile pic to far because I look heavy in that pic. I'm 6'1", so that's a bit tall for 130.

I would like to have some friends for support
