Latin ballroom dancing . . . (If you have a Wii or Kinect system, you probably have a few dance routines already like this one!) The basic core muscle contraction and hip movement in the video--done a little more unobtrusively, of course--is a good introduction to the felt sense of English rhythm. Most of the protocols in the training phase of EHIEP instruction include some degree of conscious attention to core and hip motion. (This exercise is for instructor training only--unless, of course, you are teaching in Brazil or thereabouts!) A couple of times through the 7-minute video and you got it. A month or so of regular practice and you are beach-enabled!
