tornado lord- sounds like you are i nthat big ole river, denial. you realise you are flying in the face of what EVERY PRO FIGHTER has to say on the subject? along with any doctor on the planet? doesnt this make you question what your teacher has said? Ramon Dekker, a record of 175-25, named fighter of the year in thailand (which is the highest honour you can get in thai boxing, especially as a foreigner) said when he was asked that padwork is all you need and should use for conditioning. how many pro fights has your instructor had again? and against who? I just cannot understand how you can have a viewpoint like this. its like someone saying the world is flat, being shown overwhelming evidence that it is round, yet continuing to assert that the world is flat. we arent trying to make fun of you or anything here, it pains me to see people damage themselves because of poor teaching and bad advice. and thats what you are doing.
