Is it possible to lose weight without exercise? I'm not saying this because I feel lazy, it's because I have an ankle injury. I haven't been to a physio session in ages but last time I went, I was advised only to be walking and doing my physio exercises. She did say I could use the gym but only for 15 mins at a time and only on a treadmill. It's not really worth it to pay a £45 membership fee if I can't use the gym properly or do classes. Not that I can afford it anyway! I don't drive, so I walk everywhere, including walking to work and I walk my dog, so it's not like I never move around.
