Riding a bike is fantastic aerobic exercise, and the longer and more challenging your ride, the better the workout and the better for your health. However, before you even think about biking, get the okay from your doctor.
Once you have the medical clearance -- and before you buy or jump on your current bike -- make a plan to gradually start biking. It depends on your final goals, but start with short bike rides around your neighborhood or local bike paths -- generally 2-3 miles at first, gradually adding a few miles at a time.
And regardless of the temperature or other weather conditions, ALWAYS pack enough water for your biking adventures -- and carry money with you to purchase more water along the way if you need it.
