Im afraid I just dont understand the problem with either the jump kick or the ESK, if you dont like it choose the lower options!! Take moves like that away and what are we left with????? jabs, uppers, hooks.....basically your average boxercise class! Thats the beauty of BC, the martial arts feel. Its the true essence of combat and I cannot understand instructors that dont get that, especially after the training we go through. Its sad because I think BC is so special and I would hate for it to move in a backwards direction. I think the way its going is great and it really stands out from any other aerobic training I know!
