Thor's Elite Fitness, Concord

Certified personal trainer Thor Colberg refuses to define the word challenge, as he’s found through experience that one person’s molehill is another’s Mt. Everest. In any given boot-camp session, he might have to work with a new mother, a competitive athlete, and a first-time exerciser at the same time. To accommodate all of these men and women of differing ages and experience levels, he adjusts his regimens to fit each individual and makes doubly sure that no camper is ever left behind on a run or forced to act as a bridge on an obstacle course. During these 35-minute sessions, he leads calisthenics and light weightlifting routines that simultaneously accommodate and test his students. Drawing on extensive summer camp-counseling experience, he also leads boot-camp sessions for kids.

All of Colberg’s services tend to include a nutritional aspect, as he is also a certified nutrition consultant who endorses a holistic approach to health.
