These classes are designed to keep a runner’s core strong. Core work conditions the body from the abdominals to the arms and legs. Often runners are much stronger in their lower extremities than their core. This results in an imbalance in the body that it will continuously try to remedy. Classes are held at Move Missoula, 1900 W. Broadway, C and the Runner's Edge, 325 N. Higgins Ave. Mats provided, comfortable clothing recommended, running shoes not required.
