I’m talking consistent effort over years or decades though. Thinking about how your bones are constantly renewing themselves and you have a completely new set every 5-10 years is the kind of consistency I mean. Of course this would be hindered by injury or over use before can adaptations occur. You need to give yourself recovery time no matter the fitness routine or athletic level.
I really want to try a powered paraglider. Seems fairly accessible. Costs no more than a used car. Curious about the legality/feasibility of using it to get around…
