Outdoor Sports – products, apparel, footwear and gear

My friend and I are on Weight Watchers and want to incorporate more fitness. However, it is winter and the cold weather is making outdoor activity uncomfortable.

Any ideas for some good and effective exercise activities to do indoors? We do have Wii Fits and Wii Sports, but they get boring after a while, and we want to be able to get out of the house to get some exercise.

Thank you!
