The APX method

Test first.
Train second.

Most youth training runs on feel. Ours starts with a measurement, trains the numbers that need to move, and retests to show what changed. See the tests ↗

Baseline Test

Sessions with Coach Z built around the numbers that need to move.

04
Retest

A new report shows what moved, and the next block starts from it.

Zyair Velazquez

Sports Performance Coach

Zyair Velazquez, Coach Z to the athletes, played three sports in high school, then college football, and went on to captain a professional football team in Mexico.

Before APX, Coach Z spent more than three years as head coach at an El Cajon speed and strength gym and coached varsity linebackers at Valhalla High School. A 9-year-old learning to sprint and land needs different coaching than a senior heading into a college season, and Coach Z has coached both.

Coach Z holds a bachelor's degree in Exercise Science, specializing in personal training. Expect high standards, clear coaching, and an athlete who leaves every session moving better than they came in.

What we train

Fast, agile, and mobile first.
Strong when they're ready.

Every session builds speed, agility, and range of motion. Strength starts with bodyweight and technique, and load comes when movement, growth, and age say your athlete is ready. Each session targets a number from the report, and retests keep the training and the testing moving together.

Speed

First-step acceleration, sprint posture, and arm action: the speed that shows up most in youth games.

Agility

Braking, cutting, and landing under control, so change of direction holds up late in a game.

Range of motion

Ankle, hip, upper-back, and shoulder mobility in every session. Growing athletes lose range fast.

Strength, when ready

Bodyweight and technique first. Load is added once an athlete moves well and controls each side.

The lab

Where they train.

One floor in El Cajon: racks, plates, turf, and the force plates your athlete tests on.
