Although an incorrect bike set-up can be responsible for your lower back pain, the problem may unfortunately stem more from you than from your bike. Riding with a poor posture and high degree of flexion in the lower lumbar spine is thought to be one of the main causes of lower back pain. This poor posture is clearly demonstrated in the image on the left. You will also see on the right an image, of the same cyclist, engaging their core and lower back muscles to create a much straighter line with their spine – a position that is far less likely to result in back pain. That being said, this second position requires a lot more effort and may not initially be sustainable, for some, throughout the duration of a longer ride. However, there are some great exercises that can be done to strengthen these muscle groups. We have included a small selection below.
