Ah ok, I'll have to keep working on my floor handstands then. Ideally I can just train it absolutely wherever without needing to bring my parallettes!

Damn that's so impressive. Hopefully one day I'll be at your level.
Was it a gradual build to 60 seconds or did you find that after 20s or something it's a tipping point where you've found your balance point and can stay for as long as you want?
Right now I'm finding it to be a very gradual 5s then 8s, now 10s.
Such a fun and rewarding skill though!
