While I focus mainly on teaching people how to get better results with bodybuilding, there is far more to fitness than merely building muscle mass. For people who are less serious about weight training (i.e. just putting on pounds of muscle), or for bodybuilders who are interested in incorporating some other activities into their overall fitness regimen, cycling can be a great idea.
Running, while it is a great cardio workout can be HARD on the runner's joints -- something a bodybuilder can't afford. Cycling offers many of the health benefits offered by running, but without the downsides. Therefore, a lot of bodybuilders would do well to eschew running and/or jogging in favor of more low impact cardio workouts like cycling.
One of the best things about cycling is you can enjoy it outside -- this is great news for the fitness enthusiast who feels like they spend their whole life at the gym. Also, Cycling can be just the thing for the bodybuilder looking to take it east on their knee and ankle joints as well as the layperson concerned with fitness in general. It truly is an activity which gives you a cardio workout and is fun to do because many people (myself included) find running to be BORING.
It is feasible for many to get in a good amount of exercise simply by bicycling to work because one of the advantages of cycling (as opposed to running or jogging) is it can be incorporated into your daily routine!
If you can't commute to work on your bike then you could try bicycling around your neighborhood and running errands on a bike instead of driving. Who knows, with the cost of gas now days -- you might save a lot of money!
The idea here is to work cycling into your daily life so that you don't have to make time for yet another exercise plan - after all, there's still the gym to think about! However, you don't need to spend all day, every day on a bike to get the benefits.
Experts recommend between one to four hours of vigorous cycling per week as sufficient for your cardio needs. Especially if biking to work is an option for you, this will seem like you didn't work out at all - while you still enjoy the healthy rewards of this activity.
Cycling is fun, which makes it seem more like a treat and less like a trip to the gym (although many, this author included also would count as an enjoyable activity) while providing a great workout. After all, even if building muscle is your priority, you should not neglect to maintain a general fitness routine; and that includes cardio.
