New blog?

I have a blog that is all about my weight and fitness goals on wordpress. I'm debating whether to have this as a second blog where I post the same things to reach out to more people, or to have an entirely new blog about something else! Excitement. 

I suppose I should lay my options out...

-Copy&paste from current blog    -A little boring and repetitive

-Blog about fashion and make-up    -probably wouldn't post much

-Blog about my day to day life     -a little personal to post on the internet...

-Blog seperatly about food and exercise, with links to each

-Keep wordpress blog as it is, and post measurements and pictures on this one

Decisions, decisions.....Opinions please?
