You should take a break between amounts of side leg raises. 200 per leg is not recommendable in one session, is all I am saying.
Since you are so eager to get in shape, I guess you'll like this:
Cat cow pose switching 500 times, plus
steps like this, 500 forward, 500 backward. I also recommend to do these not all at once.
As forfeit, I guess you don't really want to be gagged for 30 minutes.
