Increasing endurance, but why is most of my cycle ride in Heart rate zone 5

CV fitness comes quite quickly but it takes about 3 years for the muscles to develop and you'll be flogging a small engine until then.

That's interesting to know. I have done a lot more myself since covid. I can cycle faster at a lower HR than previously but my legs still ache after 100k.

Unless you're physically strong already

I recently started weightlifting again. I found out I still had a good portion of strength from my youth, being able to front squat my own body weight. Cycling does require a degree endurance muscle type to get the best benefits
