This article briefly examines the most popular instability training devices and provides examples of how instability training can be incorporated into traditional resistance training programs.

The countermovement jump (CMJ) is one of the most used performance assessments in strength and conditioning. Although numerous studies discuss the usability of different metrics in this test, this is often performed within the context of a specific aim. However, to our knowledge, no information currently exists providing practitioners with some over-arching recommendations on which metrics to choose when the purpose of using the test differs. This article discusses how the metrics selected to monitor during CMJ testing may differ when aiming to use it as a proxy for athletic performance, as part of neuromuscular fatigue monitoring, or as part of a test battery for return to performance in injured athletes.

Field tests have become popular in applied exercise science and sport performance enhancement programs because of their simplicity and ability to generalize results. However, numerous confounding factors may influence the validity of test data from such evaluations.

The purposes of assessment are to gather baseline data and to provide a basis for developing goals and effective exercise programs. Gathering and evaluating the various pieces of information give the personal trainer a broader perspective of the client. The process and the data collected assist the trainer in identifying potential areas of injury and reasonable starting points for recommended intensities and volumes of exercise based on the goals and fitness outcomes.

This infographic outlines a three-step process to determine the efficacy of selected jump metrics and the ability to use them in practice.

While acute inflammation is a normal response to high-intensity training, chronic inflammation results in depressed immunity and impaired muscle response. Learn about nutritional strategies to help balance exercise-induced inflammation to optimize performance outcomes.

Learning to lunge correctly can strengthen the lower body musculature, improve core stability and balance, enhance hip flexibility, and increase functionality. There are a plethora of modifications and progressions to consider.

The VO2max test is the most effective measurement of the body’s ability to deliver and use oxygen for producing energy that can be used by the muscles. VO2max (i.e., maximum aerobic power) simply stands for the maximal volume of oxygen that can be used.

Integrating unbalanced load training into a strength or hypertrophy phase, or any workout program, can add a tremendous amount of demand on the lateral aspects of the core to help the athlete develop a strong core. Using unbalanced load training may help produce increases in athleticism, balance, and motor coordination without sacrificing strength or explosiveness.
