Your last quote throws bones and muscles into one. Just so you know.

The Royal Osteoporosis Society recommends "Short bursts of activity are ideal for bones. For example, running then jogging, or jogging then walking." https://theros.org.uk/information-and-support/bone-health/ex...

Btw, don't confuse weight-bearing activities with the weight-lifting that I did quote previously. Resistance training alone, as for example cyclists do, has shown to not improve bone density as pre this meta study https://bmcmedicine.biomedcentral.com/articles/10.1186/1741-...
