Maybe you could consider buying a treadmill? I use one that has 10 inclines and up to 10mph speed. I am up to running on it now after a year. But I would give it some time with your foot to heal, I hope it feels better soon.

I have a gym membership but during the winter months when the weather is really cold and windy, I bought an old gym set with weights out of the classifieds for a good price. When I was in physical therapy for awhile they had me use super strong bands for my arms and legs to build up my muscles. I dont know if these might be options for you?
