@Ruth, I watched that series too. An eye-opener for sure!
Oh, and I don't like gyms either, I'm with you on that too. Though my weight is fine, I know I should probably be a bit more active just for health reasons... I used to go to a weekly class called "Bodytoning" - not to lose weight, but it was a good thing to use all those muscles one doesn't use usually, and it was nice. My only problem is, you can only sign up for four months in a row, and with my job, I'm at some times of the year just away too much, and there's no refund for missed classes, so it got too expensive. Plus they suddenly doubled the class size, which didn't help either - before it had been a cozy sort of 10-women-group (all ages, sizes and shapes), and then it suddenly ballooned to 20 and it got crowded... However there's new gym belong to the same mother company opening soon, it's on my way to/from work and I hope that they may have some more flexible classes. Until then, I get off the tram a stop earlier in the evenings and take a longer walk home. It's not much, but it's something and it's a good way to clear one's head after work.
