New to standup: using focus mitts

[Arashi]

I've been doing BJJ for a while and have started doing to MMA training. I bought a pair of focus mitts for my training partner and I, obviously we're kind of on our own. When we were trying them out, they felt a little awkward, in the sense that when I'm hitting the mitts I'm hitting two targets and I normally would be hitting at a face or a body.

I guess my question is how and where should they be held? I tried a search but didn't find anything.

Thanks.
