Which kind of exercise are you doing? I like roller skating very much, but if I had problems to find skates in spain (because of my foot size), i suppose that finding them in taiwan will be impossible
Besides, are there good places for roller skating in Taipei?
Well, I have the elliptic machine at home, to use when I watch TV. Wanna watch TV? Sweat it out.
Then I walk the dogs twice a day, which is not much but with them jumping all over the place, dodging cars and scooters, avoiding puddles and other raod blocks, well, it makes for a bit of calorie burning. Plus if I take them to the park, that means carrying 10 kilos on my back for 20 minutes or so -too much traffic on the way for them to walk.
Catxerersize works too, take cat and use as dumbbell.
As to where to skate, well, I see many people skating at Sun Yat-sen and CKS parks. Whole clubs. At Tai-Da campus, too. You'd be surprised about the skates, I think I saw a store across from Tai-Da's gym.
