All I have is my nightly walk 45mins or so. I'm waiting for some decent snow so I can take out my cross-country skies and walk to the Hydro-power green spots. There's one a good 3kms long only about 10 minutes walk from my house.... but so far, no snow.
Some good advice...do not try to start an exercise program in January. That's when you run into the 'resolution' people. I see it every year at the base gym. SRO from 2 JAN to around 6 FEB, and then its business as usual.
