Thread: Improving stamina indoors, and outdoors?

I ain't the skinniest guy, round 20 overweight. I want to improve stamina to be able to exercise longer and start losing weight.

I tried to start going 1 mile a day, but past few days it has been pretty cold here in new York.

How would I improve stamina indoors, and what are some ways to do it outdoors.

I feel ashamed, as I can only jog 0.06 of a mile (1:28 minutes) before I get tired and have to rest.

Thanks!

I know what we could do indoors
