About Coach J.

I have been filming and measuring athletes in Carrollton since 2014 — over a thousand of them — and the method has not changed: film it, measure it, fix what the film shows, then film it again.

I work with school-age athletes and with adults. The adults usually arrive saying they want to get fit and leave training like athletes, which is the point.

What I coach.

Every coach here measures all eight. These are the ones I specialize in.

✓Speed development
✓Biomechanics
✓Quickness
✓Power
•Running efficiency
•Change of direction
•Strength
