This excerpt from NSCA’s Essentials of Personal Training discusses the importance of education on proper running surfaces, appropriate footwear, and the benefits of cross-training in addressing overuse of the knee.

This is the NSCA’s Coaching Podcast, where strength and conditioning coaches share their experience, lessons learned, and advice about how to thrive in a highly competitive profession.

A major concern with balance and joint-stabilization exercises is to avoid potentially dangerous movements that depend on the preparedness of the athlete or patient and on the state of the healing tissue. Learn about progressions that minimize risk to the athlete or patient.

Learning to lunge correctly can strengthen the lower body musculature, improve core stability and balance, enhance hip flexibility, and increase functionality. There are a plethora of modifications and progressions to consider.

This article explores biomechanics through the lens of a fulcrum and lever system, providing personal trainers with strategies to reduce injury risk and improve performance. Visit NSCA online to learn more about personal training and program strategies for fitness.

This article examines the effects that are commonly experienced by people who have undergone knee replacement surgery as well as the exercises that can help them regain functionality.

Get to know Army Lieutenant Colonel Nick Barringer, Program Director for the United States Army-Baylor University Master’s in Nutrition. Barringer shares how he originally planned to become a strength and conditioning coach before a nutrition course inspired him to pursue dietetics. However, it was his Certified Strength and Conditioning Specialist® (CSCS®) credential that ultimately landed him his role as the first 75th Ranger Regiment (Army Rangers) Dietitian. He recounts drawing inspiration from the Navy SEALS to start the Ranger Athlete Warrior (RAW) program and seeing the Special Operations THOR3 program follow suit — laying the groundwork for the US Army Holistic Health and Fitness (H2F) system. Barringer and McMahon discuss the synergy between strength and conditioning coaches and dietitians, as well as cultural challenges and diverse training ages in tactical settings. The pair also stress the importance of sales and building relationships before discussing basic nutrition advice and pathways into tactical and dietetics careers.

With almost one million people in the United States living with multiple sclerosis, this article aims to provide personal trainers with ideas for exercises to meet the needs of these individuals.

The squat is one of the most widely used exercises in resistance training programs. The aim of this narrative review was to analyze the effect of the squat on lower-limb muscle hypertrophy. Briefly, the available literature indicates that the squat is an effective exercise for inducing hypertrophy of the quadriceps, mainly the vastii, but also the rectus femoris, although to a reduced magnitude. Multiple lines of evidence suggest little to no hamstring hypertrophy from the back squat. Although the gluteus maximus clearly participates mechanically in the back squat, few longitudinal studies exist on the topic. The limited evidence available on this topic suggests deeper squats may be more hypertrophic for the gluteus maximus, and that, squat depth beyond 908 of knee flexion may not provide further hypertrophy of the knee extensors. Despite the popularity of the many squat variations, there are still controversies surrounding their hypertrophic potential for lower-limb musculature. Further studies are needed to investigate the hypertrophic effects of different squat variations, as well as differences in hypertrophy because of squat depth, stance, barbell position, and different squat apparatuses/machines.

A significant number of resistance training injuries occur at the shoulder complex. However, there is a lack of research identifying predictive variables, which may increase the risk of these injuries. Certain exercises, such as those requiring the apprehension position (glenohumeral abduction with external rotation), have been investigated and found to be associated with shoulder pain and injury. However, there are additional exercises or positions that may also be associated with increased injury risk. The position of end-range glenohumeral extension, particularly as it pertains to a dip, is a vulnerable position that may have previously been overlooked.
