This article will demonstrate why personal trainers should consider the use of blood flow restriction (BFR) and BFR technology for appropriate medically-screened clients that provides an objective way to apply pressure, whether that is through manual or automated cuffs.

This article discusses what muscle dysmorphia is, the ways in which adolescents can fall victim to it, and how to intervene when body image becomes distorted.

Resistance training or strength training has become one of the most popular forms of exercise, because it is the only method capable of improving physical fitness and increasing muscle mass simultaneously. Among the variables of training, the relationship between intensity and volume has been extensively addressed to enhance exercise induced muscular hypertrophy. For many, mechanical stress is seen as a factor of greater relevance and, because high loads promote greater mechanical tension and high intensities are traditionally used to increase muscle mass. However, evidence has shown greater safety and similar results through training based on lower intensities and increased training volume. Thus, this narrative review aimed to search the current literature for evidence on using different training loads to promote muscle hypertrophy. An extensive nonsystematic literature review was conducted in the PubMed, Google Scholar and Scielo databases. It was possible to conclude that the use of high and low intensity promotes similar results in muscle hypertrophy in all groups, leading to the belief that there is greater safety and adherence to the use of lower intensities compared with close effort to concentric failure.

This short excerpt from Developing the Core details the importance of training the core musculature in tennis athletes.

This excerpt from NSCA’s Guide to Sport and Exercise Nutrition briefly analyzes some of the research behind creatine and its application to sport performance.

During the rehabilitation process, a client may need therapy outside of the personal trainer’s scope of practice. This article discusses safe and effective modalities that personal trainers can use with clients in the post-rehabilitation phase process.

The purpose of this article is to present the reader with the prescription of a daily specific stretching routine that can help athletes avoid the onset of injuries and chronic pain in muscle-tendon structures of the lower extremities.

This article will explain the interference effect and provide a rationale for why low-intensity steady-state (LISS) cardiovascular training may be a useful tool for those interested in improving their body composition.

Potentially, an instability training program that first involves static balance and then progresses to dynamic balance activities would improve intrinsic balance. This improvement in balance would increase movement confidence, releasing the neuromuscular system from a stiffening strategy to more unimpeded motion, force, and power development.

Dietmar Schmidtbleicher, Head and Chair for Sport Sciences at the Institute of Sport Sciences at the Goethe University Frankfurt/Main in Frankfurt, Germany—and one of the world’s leading experts on strength and power training—explains the influencing factors of force production in eccentric muscle actions. Schmidtbleicher made a rare appearance in the United States at the NSCA’s 2015 National Conference.
