Cardio The Aqua-Biking workout
Aqua-biking is also known as aqua cycling or aqua-riding and is a complement to the Aqua-fitness .
Commercially, aqua-biking, which has its origin in Italy, started only a few years ago. It is done with underwater bicycles in the areas of non-swimmers swimming pools and indoor swimming pools with a water depth of approximately 1.35 meters. Natural waters such as rivers , seas or lakes are not suitable for this application. The underwater bicycles that are used for aqua-biking, are special devices and the physical performance of the participant is measured in watts.
Aqua-Biking is used primarily to improve physical fitness. Thus, the muscles are stronger and the efficiency of the cardiovascular system improves. In addition, it can reduce weight . This is all done in a gentle way, because the buoyancy of the water protects both bands and joints , increasing the risk of overload and injury is extremely low.

During exercise, the body is cooled by water, which can secrete the body heat more easily. Aqua-Biking is more gentle on the joints than cycling on land. It also has the great advantage because you can do it whole year through, because in a pool hall there is no dependence on the weather.
