What we’re solving
An all-arm swing with no legs or core
What usually causes it
Driving from the ground up sequences the legs, then core, then arm for free power.
Drills you’ll likely work on
- Load-and-explode reps
- Hip-lead rotation
- Light medicine-ball throws
Video-based next step
Want to check this on your swing video?
Your estimate gives you a direction. Motion Lab helps validate what is actually happening with video-grounded checkpoints, a visible confidence level, and one clear retest target.
Honest by design: normal phone video is directional, not lab-grade. We show confidence so you know how much to trust each read.
