Course/Workshop Descriptions

Core-Foundations-150CORE Instructor Foundation Course

The CORE Instructor Foundation course will provide an introduction to group fitness and personal training theory and their application to program development. This program effectively brings together the worlds of core conditioning and athletic training with established body awareness principles. Effective program design relies on consideration of a broad range of concepts for training, and a complete understanding of the application of these theories. In order to bring a more thoughtful approach to the work, a series of stabilization principles will be examined and correlated with standard teachings. A number of props will be used throughout the course to demonstrate and explore the foundational principles as well as be incorporated in a Circuit Training program.

Upon completion of the CORE Instructor Foundations courses, you will have learned everything you need to:

  • Explain the theory behind the CORE principles.
  • Effectively apply CORE principles to a workout for any level participant.
  • Teach a pre-programmed CORE Circuit class in a group format.
  • Practice correct execution of exercises found in traditional fitness training.

All CORE Workshops are created by the Merrithew™ programming team.
