Hey guys

I'm a 15 y/o guy, about to finish my freshman year of high school. I don't really have many plans for the summer, so I'm thinking about starting working out or something. I'm 5 foot 7, 115 pounds. I'd love not to look like a little bitch. Can someone point me in the right direction on getting started? I know pretty much nothing about this, anyone have anything I could read/watch to learn the basics? Thanks
