Get a trainer and start riding inside! I frequently hear from my cycling friends that the “trainer is sooooooo boring.” A bike trainer elevates your rear wheel so you can ride your bike inside. Yes, it will be boring if you are riding by yourself in a small room staring at the wall! Create an environment that motivates you. Set up your bike in front of a TV. Find a radio or an iPod docking station so you can listen to heart-thumping music. Do some research on indoor training programs; high-intensity intervals will not bore you. By performing intervals, you will not need to ride for multiple hours as you do outside because there is no coasting and you must pedal the whole time. You can get a great workout in 30 to 60 minutes (or longer if your heart desires).
The choice is yours. 1) You can do nothing and waste all the fitness you gained over the summer by staying sedentary all winter. 2) You can join a gym and participate in group spinning classes; or ride on your trainer distances and intensities that are comfortable for you. Something is better than nothing. 3) For the dedicated riders, you can join an on-line service which provides programs/videos for you to follow (Trainer Road, Pain Cave, Sufferfest, etc.).
Plug in the fan, bring a water bottle and a towel, and get ready to sweat! Fly into Spring with a fitness level at or above where you left off in the Fall; feel great about how in shape you are and how all of your friends are not.
Trainers may be purchased at bike stores and on line. Do your research to see what meets your needs. More costly units tend to be quieter, which may be a factor in where you live (apartment, dorm room, etc) and what time you may be riding (early AM or late PM, during the baby’s nap, etc).
