What a strange thread. Any exercise is better than nothing and one that you enjoy and stick with is the best of all.
What is your goal? It's probably different for every person so why measure your success on someone else's scale?
I enjoy hiking my 5-10 local flat miles when I am at home. I do have to augment with running and strength work to be able to do my adventure hikes that I love (pre-COVID)- the latest was the Tour du Mont Blanc (10 days, 29,000 feet ascents and descents).
I enjoy biking my 20-40 miles on our low hills here in the Mid-Atlantic. I've gotten a bike trainer and more recently an indoor cycle with incline/decline and one day I would love to bike the Tour du Mont Blanc.
The strength work helps both of the above.
