Some gyms offer winter-only memberships. Swimming is great aerobic exercise and a good way to maintain flexibility. Use a kickboard to hold you up and kick behind it. Winter riding, whether it is on the roads or on the trails, requires not only more clothing but also a keen awareness of safety issues. Talk to experienced cyclists for tips and advice.
Skiing is the perfect winter complement to cycling.
Cross-country skiing is a highly aerobic activity that works many of the same muscle groups as cycling. Alpine skiing works the quadriceps and improves your balance, which translates into better bike handling skills. Running is also a great way to keep your cardiovascular fitness high. Unlike cycling and skiing, however, it's a weight bearing activity, so be sure to wear quality running shoes, and don't do too much too soon. To be sure, the winter season offers many enjoyable exercise choices to help bicyclists prepare for the spring g season.
