Eric Thomson, NASM, ACE, TRX


Eric began his fitness journey after graduating high school at an obese weight of 240 pounds on his 5’10” frame. Tired of the ridicule, lack of energy, and struggle with confidence, Eric began lifting weights and making better food choices. Following completing his undergraduate and graduate work in music and opera performance and spending time in that field, Eric chose to transition and dedicate his life to his passion of helping others achieve health and wellbeing. Presently Eric instructs group fitness, cycle and various other class formats for LifteTime Fitness Athletic in North Scottsdale and works with individual clients via Avenger Fitness. Eric is certified by the National Acadamy of Sports Medicine (NASM), the American Council on Exercise (ACE), and holds additional certifications in TRX, Tabata, and Weight Management/Obesity Management. Eric is happy married to his loving husband, Chris, and thankful for sharing a life-long passion for fitness with him.
