About Crossfit Endurance

The CrossFit Run Endurance Certification was developed to allow CrossFit Athletes to still CrossFit and compete in endurance sports and bring a standard to running. It brings to light the reality of LSD/Oxidative training and why it is ineffective and extremely unhealthy. It gives you the ability to understand training endurance athletes and how to make strength and conditioning a major part of the program and not a supplement.
