It’s the heavy eccentric portion of the movement: like the negative part.
It’s not normally a danger in small doses.
For whatever reason, probably that the muscles are not taking that kind of damage, the 100 air squats just doesn’t cause the same problems.
In the 4 years I’ve been here, I’ve seen rhabdo from jumping pullups and GHD situps (not from the downhill running or kb swings) but not once from air squats.
I did jumping pull-ups for the first time in ” A Bunch of Stuff”, but I came down pretty fast. Thanks for the info. Weird disease, but good to know about because after I did the jumping pull-ups I thought they were a good exercise and would like to see my numbers improve.
That’s where this scaling is so important to a beginner like me!
