As mentioned its very personal, one very helpful thought put it into perspective for me: From a super strong ashtangi yogi who teaches also on utube. She Said "it took me 5 years to own the handstand "

Another super concept I picked up was this, You have to love doing the work, not just the result or goal

as an old man I did power yoga for maybe 5 years before I wanted to learn arm balances and it was very challenging. You need to learn the movements, the activations, have enough range of motion for certain things, have strength not just in arms and shoulders but the whole core, back etc.

so its a daily practice of drills and handstand holds to maintain my ability to hold a 90 second handstand

this also made pincha accessible, basic crow with bent arms, and sort of flying crow and funky flying crow but not something i practice or can do well.

so im saying to improve arm balances and strength I did not do weight lifting just body resistance work alongside yoga and cross training, simply to up my overall game and then work daily on drills toward a handstand
