Adding achilles thoughts here since so many have talked about it- When I was a young teenager I partially tore my achilles in a silly accident at home. I was in a cast for roughly two months, the last few weeks of which was a walking cast. Unbeknownst to my doctors I did start walking tip-toe in my cast a few steps at a time and then tried tumbling in my walking cast (quickly switched to only forward landings because you can’t tuck your toes on a low landing in a cast and owwww). I walked out of the doctor’s office the day I got the walking cast off, but running didn’t feel good for a couple of months. I think I was back to full gymnastics in five months post injury, though I developed an “ouch” scale based on the color of my heel after various activities. It frequently turned black when pushed. But if a lower level athlete could tumble on it soonish a couple of decades ago, I suppose it’s not impossible that a high level athlete with great medical care might be able to do some at three months.
The quality and difficulty of what Artur is doing is what throws me, though. You don’t get those skills that clean on no training.
Also knowing what that feels like on lower level skills, and that big skills are likely much worse, I cringe constantly watching him.
I have recently developed achilles tendonitis in that ankle and I am pretty sure it’s related to my pushing it too fast when I was a kiddo.
