Hibernation is not an option

Scientists are currently researching how bears are able to sleep all winter and lose the fat they pack on prior to hibernation yet almost none of their muscle mass. Until science reveals the magic behind hibernation, I will need to work out over the winter to maintain the muscle that I have built up during the summer, though heavy clothing will hide all sins.

I have considered my winter workout options and list them here:

Running - Running in winter is unpleasant, but it is safer than biking in the cold, and burns more calories in less time, minimizing my time outdoors. Personal record: -13C. Goal: break personal record if global warming doesn't get in the way.

Swimming - Regular public displays in a bathing suit will give me incentive to keep the fat under control...oh, and the exercise will be good, too. Goal: swim no more than once a week for 30 minutes, because chlorine is hell for hair.

Snowboarding - Snowboarding has made me feel a kinship with MMA fighters, because since buying my own snowboard two winters ago, I understand how taking a beating is exhausting. Plus, all the push ups I do to pick myself up after falling over are awesome for defining my arms. Goal: snowboard when snow is present.

I will also be participating in other cold weather activities like stamping my feet at the bus stop, jumping over moats of snow run-off, and heavy lifting of sweaters, hats and coats.
