Break-Dancing/Rhythm

Really interested in getting started, not really looking to be a professional in such a hobby, but I want to have at least some basic skills.

I'm starting from knowing-nothing-at-all level.

I need some tips, especially pre-training tips for getting ready to break dance, such as push ups, sit ups, laps.

Then the basics, and finally the rhythm training, such as simulation or activities that improve my rhythmic beat.
