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.

Certified Strength and Conditioning Specialist Exam Description. The Certified Strength and Conditioning Specialist® (CSCS®) exam is comprised of two sections that test the candidate's knowledge in the Scientific Foundations and Practical/Applied areas.

Before registering for the CPSS™ exam, you must first complete an application, submit your eligibility documents, and receive permission to test. Begin this process in advance of your desired testing date, as applications may take up to 30-days to process.

The following erratum, a correction to a published article, appears in the October 2015 issue of the Journal of Strength and Conditioning Research.

The CSPS examination reflect the most current and accepted KSA standards within the health and fitness industries. Further, the examinations may be developed from references that may be in addition to resources listed below. NSCA materials survey important content area, but are not a comprehensive study of the Exercise not a comprehensive study of the Exercise Sciences.

The NSCA announces 2025 Salary Survey results conducted by Employers Council, showing a 6.7% annual growth rate since 2018 and $68,089–$98,564 average salaries.

The NSCA certification exams are based on the analysis of tasks needed to be competent in a specified job or role. The exams measure a candidate’s knowledge, skills, and abilities (KSAs) compared to a predetermined level of competence. It is not a test that recalls information from a textbook like a college course. Before you start preparing ensure you have chosen the right certification for you.
