Taegeuk form 1 to 8🤣 God, it's feels nostalgic))
By the by, those are not some form of intense exercise. Basically, taegeuk is a set of moves, intended to fit m. artist's belt, timewise up to two minutes max. Might differ here and there, in our school form 1 was studied at green belt and form 8 at brown. Black and above had their sets. As a complete set, it's focused on precision of execution, so it was hardly taxing. As for complexity of the moves, the hardest move from form 8 was two straight head kicks in one jump - which might sound scary, but it's relatively easy for a martial art so heavily focused on legs (especially for taekwondo wtf, you only use arms for blocking there).
Sorry for rambling) guess I am getting old...
