Sit-up
Stylized sit-up: sit low with knees up (deep root.y drop), hands behind the
head, and rock the torso between leaning back and curling forward, on a loop.
How
- Setup: knees up (
*UpLeg:[90,0,0], *Leg:[100,0,0]), root.y:-0.45; hands
behind head (LeftUpperArm:[20,0,60],LeftForearm:[0,0,-130],
RightUpperArm:[20,0,-60],RightForearm:[0,0,130]).
- Back (start):
Spine:[-25,0,0], Chest:[-10,0,0].
- Up (crunch):
Spine:[40,0,0], Chest:[20,0,0]. Loop between the two.
