In 2017, I somewhat randomly picked a physical fitness goal to hit by 2019: to do a pike-to-handstand (link). I keep seeing it done in "people are awesome" youtube videos, which I watch occasionally as an end-of-day feel-good mood booster, and they look amazing. I found a couple sites that broke it down into separate parts, and I've been working on them as part of my regular workouts.
In a similar vein, NerdFitness, the geeky website I use for fitness information, released a "Rings and Handstands" pack that takes you step-by-step on how to do things like handstands, handstand push-ups, ring L-sits, ring muscle-ups, and ring front levers. It was half off, as an introductory price, so I went for it, and have been working my way through some of the progressions there, as well, since many of them target the same muscles and skills as pike-to-handstands.
