01 — Run / Jump / Throw
First, run right.
Run, jump, throw. Master the fundamental movements behind every sport, matched to each child's age and growth.
Bangkok / Ages 1–15 / Sports Education
Faster. Stronger. Totally hooked.
When kids learn to run right, every sport gets more fun.
A former professional footballer grows your child's "I did it!" moments
through track & field and multi-sports.
The form takes about 1 minute — not sure which class? We'll help you choose.
More Than a Sports School
You learn
more than just sport.
Running faster. Doing something for the first time. Cheering on a teammate. Each moment builds a child's confidence. ASA is not a school that only teaches winning. Through running, thinking, and working with friends, we raise children who can take on challenges by themselves.
02 — See / Think / Move
See it. Decide it.
Read the situation, choose, and move. Eight sports build decision-making, teamwork, and sports IQ.
03 — Try / Respect / Grow
Fail. Try again.
Greetings, discipline, challenge, respect for teammates. On the field, children learn to stack small wins and losses into strength.
8 Sports. More Possibilities.
Eight sports to find
what you love — and excel at.
Before specializing, children explore a wide range of movement and discover the sport that fits them. A seasonal rotation builds a broad, deep athletic foundation.
