As a pilates teaching meat head I have one true love exercise that always gets my entire trunk working (outside of ab roll outs, plank variations) - teaser. Typically I do teaser on a reformer but the mat based one is good too
"There is no modification to this...you can either do it, or you can't."
I can't.
I can do a half-a#@ yoga boat pose with less-than-straight legs, with external shoulder rotation.
If you can, I'm impressed! ??
Admittedly, the more gymnastics-oriented end of the bodyweight spectrum are things I have never practiced (or at least not since I child when I was horsing around on monkeybars).
V-ups, L-sits, manna....all outside my repertoire.
Hollow and arch body holds, ring rows and ring push ups are about as gymnastic-like as I get.
Nothing against them, but I've only got so many hours a week to train, and anything that is high-skill will subtract from my sports-specific skill practice to some degree. At some point, I have to choose if I want to keep getting better at clean & jerk for competition, or start learning the planche push-up from the newbie level....
Which brings up an interesting point:
Bodyweight training for GPP vs bodyweight training as prep for gymnastic moves.
One of the things I'm less than personally enamored with about some of the most popular bodyweight routines (Reddit bodyweight, Gymnastic bodies, etc) is that everything is prep for going gymnastic moves.
Which is great if you want bodyweight to be your main or only modality.
But it's harder to integrate them with other modalities, as the the emphasis on static holds doesn't transfer as well to dynamic sports, the equipment goes in a different direction that makes it harder to do at home (e.g. parallel bars), and (like Olympic lifting) the skill component is no joke amount of practice at higher levels.
