Does cycling weaken bones?

This question is about Cycling

Yes, observational research suggests that cycling can reduce bone density most likely because cycling is a non-weight-bearing exercise [1]. Studies have found that two-thirds of professional cyclists had abnormally low bone mineral density (BMD) values, and riders who train between 3-8 hours a week have similar results [2]. Combining cycling with load-bearing exercise such as running, weight training, tennis, and hiking may help offset the impact of biking on bone health [1].
