a-skip

name	a-skip
description	Performs the track A-skip drill: a rhythmic skip with a high knee drive and a small hop, traveling forward via a sequence. Use when a command mentions A-skip, a skip drill, sprint skip drill, or high-knee skip drill.

a-skip

A rhythmic skip: drive one knee high with a little hop, land, switch — a sprint warm-up drill that travels.

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 high knee (UpLeg~100,Leg~90) with a root.y~0.15 hop; arms drive opposite.
• durationMs ~2200.

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.
