ladder-drill

Rapid in-place high-tempo steps as if running through an agility ladder.

Composes: move-leg + balance-and-posture

How

• Use a sequence with loop:true. No root translation (in place).
• Quick alternating moderate knee lifts (UpLeg~40,Leg~50), light and fast.
• durationMs per cycle ~1400.

Example

• "do a ladder drill" -> {"durationMs":1400,"say":"Quick feet—ladder!","sequence":{"loop":true,"frames":[{"t":0,"pose":{"LeftUpLeg":[40,0,0],"LeftLeg":[50,0,0]}},{"t":0.25,"pose":{"RightUpLeg":[40,0,0],"RightLeg":[50,0,0],"LeftUpLeg":[0,0,180],"LeftLeg":[0,0,0]}},{"t":0.5,"pose":{"LeftUpLeg":[40,0,0],"LeftLeg":[50,0,0],"RightUpLeg":[0,0,180],"RightLeg":[0,0,0]}},{"t":0.75,"pose":{"RightUpLeg":[40,0,0],"RightLeg":[50,0,0],"LeftUpLeg":[0,0,180],"LeftLeg":[0,0,0]}},{"t":1,"pose":{"LeftUpLeg":[0,0,180],"RightUpLeg":[0,0,180],"LeftLeg":[0,0,0],"RightLeg":[0,0,0]}}]}}

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.
