I need a guys advice! What do you like to talk about?

I really like this guy in my gym class, but I haven't talked to him yet because I have no idea what to talk about! What is a good conversation starter and how can I find out more about him through conversation without making it boring? I need some answers!I need a guys advice! What do you like to talk about?
Try to partner up with him in gym and drop hints. Or ';accidentally'; hit him with a ball or something to break the ice, then if you can find something you both have in common and start a conversation. Another thing you can do is just flat out flirt with him guys actually like this. Find something that looks good on him anddrop a line and walk away, you'll be on his mind all day.I need a guys advice! What do you like to talk about?
well guys usually like stuff like sports, but the best thing to talk about is always music.
