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.

As a personal trainers business and clients grow a limitation of time and number of clients one can fit into a day is often dealt with by charging more per session or offering more time slots. This article goes over how to implement group training to maximize results for clients and profitability for a personal trainer,

A sound year-round aerobic endurance training program should be divided into sport seasons with specific goals and objectives designed to improve performance gradually and progressively.

The career path of a personal trainer inherently presents a certain amount of instability and unpredictability, but this does not have to last. There is no reason that personal trainers cannot make great money, afford health insurance, save for retirement, and create more freedom in their lives.

This excerpt from NSCA’s Essentials of Personal Training, Second Edition briefly reviews the role of oxygen uptake in exercise.

This Kinetic Select from NSCA’s Essentials of Personal Training, Second Edition gives a brief overview of respiratory adaptations, and how aerobic interventions of duration and intensity can be used for specific adaptations for endurance training.

The path to actual integration of mental and physical training for the tactical athlete is paved with growing empiricism. The current challenge is to sustain creative development of functional approaches and demonstrate that integration can deliver potential benefits.
