I need some advice /fit/. Long time lurker, never posted till now. 18, senior in high school. I was a little chubby at the beginning of the school year(you couldn't really tell as long as I had a shirt on), then got sick and lost a few pounds. Started lifting and running(mainly sprints 20m-400m and some distance). Now whenever I take my shirt off some people say I look way too skinny. I think I probably lost 5-10 pounds, all of it fat. No idea what I weigh. So, how skinny is too skinny? Look like 2 pounds heavier than pic related minus those gay ass tats.
