A dual action exercise bike combines upper-body workouts and lower-body workouts by adding moving handlebars to a common form of stationary bicycle. The dual action exercise bike can be found in most modern gyms and fitness centers. Its ease of use make it a great choice for a low-impact workout that provides a high level of aerobic and cardiovascular exercise.

The dual action exercise bike is the result of the increasing evolution of indoor aerobic equipment. The upright bike was first invented to bring the advantages of traditional biking indoors for added convenience. These upright bikes consisted of a standard bicycle mounted on a frame and raised slightly off the ground. Pressure placed on either of the bikes tires added resistance and increased the intensity of the workout.

The dual action exercise bike works like a traditional stationary bike, but with an added feature in the form of moving handlebars that are attached to the pedals. This causes the bike to work out not only the user's leg muscles but also the arm and shoulder muscles. If the rider wishes to focus on either the legs or the arms, part of the dual action bike can be disabled. The degree of participation also can be adjusted in most dual action exercise bikes to allow for an increased focus on the arms or the legs without completely removing the other from the workout.

The type of exercise that a dual action exercise bike focuses on is low-impact aerobic exercise. The term "low impact" means that there is only a little or gradual pressure on the bones and muscles during workout. This makes low-impact exercise ideal for those who are recovering from injuries or have more permanent conditions such as a bad knee or advanced age.

Aerobic exercises are those that focus on stamina and cardiovascular development. Aerobic exercises will help trim off excess weight and help build endurance, but they generally will have only a marginal impact on muscle development. Core muscle groups will be toned but will not experience a major increase in size.

The dual action exercise bike offers all the advantages that modern indoor exercise equipment offers. It can be used indoors and set up away from distractions for those who want to focus on the workout, or it can be placed in front of the television for the easily bored. When the arm function is being used, reading is the only activity that cannot be performed as it could be on a normal stationary bike. The price of a dual action exercise bike is competitive with other exercise equipment, ranging from $200 US Dollars (USD) to $1000 USD.
