12U linebacker with good effort but late first movement
Age 12, linebacker, high effort, parent concern around being near the play but not finishing it.
Context only
This is development guidance, not a guarantee of performance, recruitment, roster status, or medical fitness.
What should he work on first?
AthleteOS starts by translating the parent question into a first evaluation point.
What changed
The file translated the issue into first read and first movement quality instead of only more conditioning.
Week-one direction
Read-and-trigger reps with one cue: move on the correct key before adding contact.
Next measurements
10-yard split, reaction note, coach note on first-step reads
Copy this when a parent asks a similar question.
Use the case file as proof, then ask for the athlete's sport, age, position, and biggest concern.
Football parent example: 12U LB: before more speed work, evaluate whether the first movement is late or just physically slow. This is the kind of first-priority read AthleteOS is built for: not a generic drill list, but a clearer development order. https://athleteos-site.vercel.app/case-files/football-12-lb-trigger-speed
