Nathan's approach is positive and based on improving functional movement. His use of TRX is fun and effective.  Nathan provided me with nutritional coaching to support my training program. In six months of working with Nathan I achieved excellent results. I lost 40 pounds and went from wearing size 38 pants to now wearing size 32 pants. My strength and personal confidence also improved. Thanks to Nathan, I am in the best shape of my life and feel healthier than ever.

I was amazed at Nathan’s knowledge of the human body and its muscularity. I was further impressed at how well-prepared he was at each & every class; concentrating on core, back-upper & lower, legs-calves, ankles & feet and arms-shoulders, biceps & triceps. Not one area was neglected. And his natural concern and caring was evident for each & every student whether a beginner or expert. The feeling of closeness and unity of purpose is very evident at each class.
