I think it's fun with a friend (did that years ago), but trying to get back into lifting by myself now... is boring. I quit each session sooner than I should, so I don't see the same gains. I'm not sure how to get excited about it when I am by myself, other than playing music to pump me up, which I'm not always in the mood for.
