lol melbourne shuffle!!!!
i used to be ace at it when i was younger act still am pretty good the shuffle is the sort of dance one can only improve on with lie rave experiance a good excercise for most noobs is this called 4 beat excersie
4 beats left 4 beats running man backwards 4 beat shuffle right and 4 beat running man forward so in effect you should go arround in a square when you get abit more confitorbale with that you can try going diagonal and a exadureted track each 4th beat
eg 4 beats left spin running man 3 or 4 diagonal rightso it ends up like a triangle your shape should look like a dimond/ 2 triangles
best hint i can give is be original worst thing is looking like some malasian shuffler (malasian shufflers all dance allike no originalality/they dance in crews/ the batte in short they are total tools that no one likes) becsue its not about being better than next guy but enjoying yourself so asloing as you are doing that ost of time it will be reflected in ur dance thus makeing it unuiqe keep on rock'n dude
