Killer workout

Just finished another killer workout.  Trimetrics has us raising our heart rate, intertwining cardio and weight training, in a way no other trainer does.  It is amazing.  Of course, I feel like  a dork some of the time because I have balance problems and bad knees, but that's ok.  I finished class today drenched in sweat and almost done with my first 1/2 gallon of water.
