New to Blogging

Truthfully I don't know where to start with doing things here, it's a new space to me and an old, mostly forgotten concept. My goal on being here is to connect with others and socialize, since I lack it in my life due to my job, however I don't know where to begin with blogs and bulletins. I'm unsure of what people are interested in, but I suppose the charm is in doing my own thing, isn't it? I'm quite into fitness and I have a good number of hobbies which I could post about, to infodump on. So, to the few people I've interacted with so far, I appreciate the welcome to the space.
