well i dont know if this is an option for you, but i try to go to the gym at least 3 times a week, its a big help and i like it much more than playing sports. there is equiptment for all kinds of things so you can lose weight and build muscle. nobody wold judge you there because thats the reason to go to one.
May the wind always be at your back
and the sun upon your face,
and the winds of destiny carry you aloft
to dance with the stars...
