This article explores the possible causes of low back pain, as well as three potential strategies that a personal trainer may use to work with someone dealing with low back pain.

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 article will explore aspects of the struggle of parents to maintain personal wellness with pre-school age children and offer strategies that may help personal trainers or their clients increase quality of life

This book excerpt discusses how to maximize sprint quality during training sessions.

This article is the second of a series of articles on strength training practices for rowing and seeks to provide information on periodization strategies for rowers of different competitive levels and schedules, as well as include sample periodization plans and sample programs.

This article details an example assessment battery that could be used to measure the relative health and fitness of community service officers (CSO) within the context of similar populations.

This is the first part of a four-part series that will address implementing a comprehensive evidence-based approach to proper movement patterns in order to reduce movement dysfunction in Marines.

This article provides the first academic history of the barbell back squat and its evolution from a bodyweight exercise in the 19th century to a loaded exercise used for a variety of purposes in the present age. In doing so, the article highlights three key drivers in the evolution of the back squat—changes in equipment, the diversification of strength sports, and scientific communication concerning the safety and efficacy of the movement. The goal of this article was not to provide a dry and irrelevant history but rather to stress the complexity of the squat’s prominence within fitness programs and the need to hold a nuanced view toward the “optimal” way to approach this movement. It examines how the movement evolved from being primarily done on the tips of one’s toes, to a loaded movement on tippy toes, to a flat-footed movement. By contextualizing the back squat’s history, this article challenges rigid notions of “correct” squatting technique and encourages a more nuanced understanding of exercise selection in strength and conditioning practice. It concludes by highlighting the importance of critically examining the social construction of knowledge in fitness and sport, and the value of historical perspective in informing contemporary training practices

Biofeedback is a tool that not everyone knows about, yet many coaches and athletes could benefit from using it. This article will describe the psychophysiological principle, introduce biofeedback, and provide descriptions of two biofeedback modalities that may be useful for strength and conditioning professionals to improve performance.
