This article describes two different methods for testing core muscle power. Both of the described methods utilize medicine ball throws.

Potentially, an instability training program that first involves static balance and then progresses to dynamic balance activities would improve intrinsic balance. This improvement in balance would increase movement confidence, releasing the neuromuscular system from a stiffening strategy to more unimpeded motion, force, and power development.

In this session from the 2015 Personal Trainers Conference, dietitian Dawn Weatherwax explains how the health of the digestive system affects overall health. Learn how gastrointestinal health impacts fat loss and muscle gain, the signs and symptoms of poor gut health, and foods and supplements that have been shown to have a positive impact on gut integrity.

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.

The manipulation of resistance training (RT) variables is widely considered an essential strategy to maximize muscular adaptations. One variable that has received substantial attention in this regard is RT volume. This infographic provides evidence-based guidelines as to volume when creating RT programs designed to maximize muscle hypertrophy.

The expression of mechanical “muscle power” and the advanced training methodologies used to optimize it are explained by Duncan French in this session from the 2015 NSCA National Conference. By overviewing training strategies utilized with world-class athletes, this session links science with advanced training techniques designed to augment muscle power.

Learn how diet and strength training in the absence of aerobic exercise can be used to improve body composition through simultaneous fat loss and muscle gain. In this session from the NSCA’s 2016 Personal Trainers Conference, Todd Miller demonstrates how to use body composition and metabolism measurements along with popular food tracking apps and activity monitors to design individualized diet and exercise strategies. CEUs available.

The purpose of this article is to compare and contrast popular methods used to reduce muscle soreness. The article looks at caffeine, cold water therapy, BCAAs and aerobic exercise and briefly examines their efficacy in treating DOMS.

This short excerpt from Developing the Core details the importance of training the core musculature in tennis athletes.
