ANAEROBIC OR AEROBIC??
Since most weight-training activities last less than 3 minutes in duration, (regardless of actual workout time), weight-training is an anaerobic activity. This means that the primary fuel sources will be either ATP or Glucose. The aerobic (oxygen/fat) fuel system does not come into play. Therefore, fat isn't burned as a fuel source during weight-lifting activites. Remmeber, even though weight-traing does not burn fat, it does increase the body's fat-burning potential.
