LEARNING OBJECTIVES • Understand the importance of core stability exercises for healthy individuals.

• Understand how to perform resistance exercises for the development of muscular endurance, muscular strength, and muscular power in the core musculature.

• Understand the potential advantages and disadvantages of performing resistance exercises on unstable equipment (e.g., Swiss ball, wobble board, and balance disc).

Personal trainers are encouraged to use a periodized approach for core training that emphasizes different muscular characteristics for complete core development. Learn how to apply this approach in your practice through this practical, hands-on feature article.

Jeffrey M. Willardson, Ph.D., is an assistant professor in the Kinesiology and Sports Studies Department at Eastern Illinois University where his research focuses on physiological adaptations to different types of resistance exercise.
