First, meet Amber Hunter. She is Senior Instructor at START Fitness and an awesome one at that. She is inspiring, motivating, and incredibly dedicated and hard-working. Amber has some great blogs herself; they are here and here and here.
Next, meet Sgt. Ken. He is the fitness genius behind the program. It goes without saying that he is a great motivator, unbelieveably dedicated, and a BEAST of an instructor.
He's really only about half as scary as he looks.
