The purpose of this article is to provide personal trainers with a review of common muscle extensibility tests of the lower extremity.

This article will discuss the role of strength training, stretching, and functional mobility exercises in reducing falls in older adults and provide a guide for creating a program.

This excerpt briefly explains myofascial release, self-myofascial release strategies, and benefits of these techniques.

In addition to standard health, fitness, or sport assessment guidelines, several guidelines exist for the fire service. Since each agency is different in its preferences, capabilities, and philosophies, applying a standard recommendation may not be possible. This article introduces basic decision-making considerations for fire service assessment batteries.

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 study published in the Journal of Strength and Conditioning Research compared the muscle activation level of the gluteus maximus, biceps femoris, and erector spinae in the hip thrust, barbell deadlift, and hex bar deadlift; each of which are compound resisted hip-extension exercises.

This infographic looks at the percentages of optimal muscle activation in variations of the hip thrust.

This Kinetic Select from Developing the Core reviews the effects of muscle activity when performing exercises on unstable surfaces.

This article provides a brief overview of literature where regional hypertrophy was reported. It also discusses the basic science and application of regional hypertrophy training.

Almost all functional movements of the trunk are combinations or variations of four basic movement patterns: trunk flexion, trunk extension, trunk rotation, and trunk lateral flexion. This article lists exercises to address each of these movement patterns.
