Frankly speaking..... I find that swimming actually works up an
appetite for me.
I end up eating a lot after a swimming session. 
I still love jogging - no special equipment needed (except a
good pair of running shoes), and it can be done virtually anywhere
at any time.
tat's the problem lor... swimming won't lose much weight and i'll
prob end up eating more...
thing is i can't jog now leh... i ran after the train the other
day, i can feel my spine hurting >.< i can't even go walk in
my neighbourhood for safety reason, and walking with bubble is
not of much help >.<
