Short, blond, chemistry student, trying not to look like my mother.

I'm going to attempt a reward system:
At 57kg I will buy new snickers
At 55kg I will have a professional pedicure
At 53kg I will have a day at the beach
At 51kg I will go camping and swimming at the Dead Sea
At 49kg I will be 49kg!
And if I could keep the weight off for 1 year, I'm going to Yellowstone, no matter how much it will cost, no matter what my professor will do to keep ...

I'm setting a goal for this summer: be fit enough to join a lifeguard course.
To be admitted I need be able to dive for 25m (hold my breath for one pool length), swim 50m front-crawl in 42sec and swim 50m breast-stroke in 52sec.
I don't really want to be a lifeguard in the pool, it seems too boring, but I want to be fit enough to do the course.
After I accomplish that, I think I want to take a self-defense class or kick-boxing.
