Since attending the workshop at RVC last fall, and since beginning my study, I have taken a consistent position that MTS is the only certification that I would recommend. As discussions have ebbed and flowed here (and I have totally given up) I have asserted it is the certification that makes the most sense for our broad population which includes all ages and abilities from sedentary through athlete. I also contend it is the perfect alternative to all the Crossfit hype because MTS provides as much challenge as anyone would need but DOES SO WITHIN THE CONTEXT OF SOUND EXERCISE PHYSIOLOGY! (I get really annoyed at the dangers of less scientific and/or informed training!)
