i would like to buy a yoga /pilates dvd but in a certain format.it would be nice to run through a complete workout ,second by second with the instructor,as aposed to having to PAUSE the film to carry out instructions.ALSO ,no big blow up balls etc...i want to be able to do this on holiday,camping,on business trips ,so just me and a mat would be great.so if you know of a REAL TIME dvd please let me know.many thanks jon
