What is the least common denominator for Taekwondo? By that, I mean, what is the core curriculum that, regardless of TKD organization or lineage, regardless of the school's proclivity towards traditional, modern, sport, self-defense, etc., you expect Taekwondo students to know how to do?
From what I can tell, the commonalities between TKD schools are:
- Horse stance punches
- Kicks, including: front, roundhouse/turning, side, axe kick, crescent kick, hook kick, and spinning back and spinning hook kick
- Kicking footwork and combinations
- Forms
- Sparring using kicks to the body
Everything else, including punches, other hand strikes, other targets in sparring, weapons, self-defense, grappling, etc., all of those seem to be bonuses if your class offers them. That's not to say they aren't encompassed by the umbrella of Taekwondo. But that it's not something that all Taekwondo schools have in common.
