Thanks for that.
I am more on the lean side, though struggling to lose the last 10kg to get to 75kg. My goal is strength, but not bulk, and a posture/profile that is amenable to a military/aerospace audience, as I am shopping our materials science stuff to EU investors and meet with folks who like to feel they are among their own. Like unto but lesser than your biking, my "endurance training" is walking a neighbors' tiny little Yorkshire, who runs me ragged up and down the hills for an hour or more each day, usually more. No kidding, my thighs and calves are much stronger now, my overall balance and stability, too. I am always shocked at how that little fellow can go, go, and go.
As an aside and while on the topic, I am now advised by a man with decades of experience as a Gurkha and in the French Legion. He quotes Hemingway and is surprisingly erudite, at least compared to my (biased?) expectations. One of my partners is from India, too, meaning that lovely subcontinent is up for a visit, hopefully in January, the multiple vaccines for which give me another motive to be in shape.
