If you like toned and supple limbs but don’t like the high impact muscle-building effects of lifting weight,then look into a commercial recumbent bike.
Recumbent bikes are easier on the lower back (lumbar spine) due to the way that you sit in the bike. While an upright bike has you hunched over the handlebars, a recumbent bike encourages better spinal posture.
Recumbent bikes are gentle on all your joints. Your lower back is supported by the bucket seat and your knees and ankles are protected from potential injurious impact.
The fact that the seat is larger on a recumbent bike tends to be one of the most enticing features. An upright bike generally has a smaller seat and can be uncomfortable for many riders.
Recumbent bikes are generally safer because you cannot stand up on the pedals. This eliminates many of the injuries that occur when using an upright bike.
A stationary recumbent bike is a good choice for most people with neurological conditions since the bike provides a workout for individuals of all ability levels. It is safe and provides a low impact total body workout.
Due to the low impact the recumbent bike reduces the risk of pain and can build strength. If your back and hips are affected by rheumatoid arthritis, a recumbent bike may be easier to use due to the reclining position with your weight spread over your back and buttocks.
