Thank you, @galenkp!
Decrepit, broken down body?! With this attitude, it surely won’t! But with the right mindset and proper training, I am sure it can take you to even greater adventures :). If only you wish it :)
I’d recommend checking gymnasticbodies :D they often share stories of their clients, who started training at any age, achieving amazing results. It’s so inspiring, that I can almost imagine myself as a super fit granny, climbing some high mountains. How cool it would be :D
