Athlete Testimonials

Erin Carson’s strength training system is unlike anything I have ever done before. Doing these exercises twice a week allows my coach to push me even harder in swim, bike, and run disciplines. It is great for injury prevention and gives my body the balance that training for triathlons takes away from it.

World Champion Triathlete

Since I started working with Erin in 2014, I feel like a completely different athlete. I’m more stable and powerful, and can back up multiple hard training sessions without breaking down. Erin’s program is specific for endurance training, and her periodization into different phases of the year allows me to improve throughout each season.

Paula Findlay
Olympian and World Champion

My work with ECFIT strength and conditioning over a period of two years helped my performance more than I could have expected! The gym work was one of the most valuable sessions of my week. Keeping on top of things in the gym helped me stay injury-free and race consistently at a high level.
