Now that it's chilly out, and the roads are covered with snow and ice, you're not about to get on your bike and go for a ride.
Don't go out and spend tons of money on a stationary bike - you can transform your favorite bike into a cycle trainer.
Here's how it works - remove the bike's front wheel and mount your back wheel into the cycle trainer mounts elevating your bike. Although, they can be pretty pricey, ranging from $100-300+, the cycle trainer beats buying a whole new piece of exercise equipment.
You can also use rollers - but they are for more experienced riders to improve balance, because they require more concentration than just hopping on and going for a ride.
Fit's Tips: The Kinetic Road Machine comes highly recommended because it attaches and releases to your bike easily and folds in half for easy storage. Plus, it's quiet enough to use while watching TV so you can catch up on all those shows you recorded on your TiVo.
