Exercise help

vixinyo

I posted not long ago asked for advice with my hip pain. Since then i have been to the doctor, i've had an x ray and been told i have a stress fracture in my hip. They want to do an mri scan next week but for the next 2-4 weeks i have to walk with crutches and not drive or exericse. I'm scared i'm not going to lose any weight if i'm not exercising. Does anyone have any ideas for exercises i can do which wont effect my hip but not swimming because the pool near me is expensive. Also im finding it very hard to walk with the crutches, does anyone who has used them before have any tips to help me walk with them?
