System of Strength

Gretchen Dusseau and Keri Crost faced a challenging paradox: how could those with little time achieve the level of fitness their body needs?This is when they founded their own fitness philosophy, launching System of Strength.

At SOS, Gretchen and Keri's team take participants through a five-part training system that covers metabolic, eccentric, strength, and isometric training, with a healthy smattering of stretching and diet tossed into the bargain. This approach guides each of SOS’s classes, creating dynamic workouts that incorporate exercises such as plyometrics, yoga poses, and Pilates combinations that can be adjusted for every fitness level.

Gretchen and Keri empathize with their clients, understanding how easily mental obstacles and everyday distractions can get in the way of a fitness regimen, what with family obligations and smart phones that need to be fed every hour. To help clients soldier through these challenges, they pepper SOS’s site with motivational quotes and posts success stories as sources of inspiration.
