butt-kick-run
A traveling butt-kick drill: snap each heel up to the seat while moving forward.
Composes: move-leg + move-arm
How
- Use a
sequence with loop:false. Frame root is ABSOLUTE; compute the travel axis from state.position+state.faceDeg (0=+Z, 90=+X). The example assumes origin facing +Z.
- Alternate a fully flexed knee (
Leg~130) with the thigh near neutral; arms pumping.
durationMs ~2200.
Example
- "butt kick run" ->
{"durationMs":2200,"say":"Heels to the seat!","sequence":{"loop":false,"frames":[{"t":0,"pose":{"LeftLeg":[130,0,0],"RightForearm":[0,0,90],"LeftForearm":[0,0,-90]},"root":{"z":0.6}},{"t":0.5,"pose":{"LeftLeg":[0,0,0],"RightLeg":[130,0,0]},"root":{"z":1.2}},{"t":1,"pose":{"RightLeg":[0,0,0]},"root":{"z":1.8}}]}}
Limits & posture
Keep ≥1 foot grounded except at a jump's airborne apex; stay inside human joint ranges and keep weight over the support — see balance-and-posture.
