Comprehensive training means you have not done a weekend workshop on a single piece of apparatus or simply completed an online course or workshop. It means you have done apprentice hours and extensive hands-on training. Many programs today teach only reformer or mat, I teach the whole system with all the apparatus designed by Joe Pilates.
