This excerpt from Developing the Core briefly defines closed- and open-chain exercises and their respective roles in training.

A review of the literature concludes that a strength training program including low-intensity to high-intensity resistance exercises and plyometric exercises performed 2 – 3 times per week for 8 – 12 weeks is an appropriate strategy to improve running economy in highly trained middle- and long-distance runners.

Specificity of training involves an analysis of physiological, anatomical, and psychological needs for an activity. This article explains how to create a well-designed program that takes exercise specificity into account.

Strength and conditioning coaches that temper their posterior chain exercises with some threshold training and specific trunk exercises designed to break the extension/compression stabilization strategy (ECSS) to restore proper stabilizing strategies may find their athletes will move better, get injured less, and actually perform better.

John Hofman, CSCS, MS, spoke at the NSCA's 2013 TSAC Conference on preventing injury when providing firefighters with an in-house training program. In this hands-on presentation, John demonstrates exercises and prevention strategies.

Robert dos Remedios identifies essential movement patterns and describes multiple exercises for each movement category in this session from the 2015 NSCA Personal Trainers Conference. Learn program designs that are effective, efficient, and balanced in nature, as well as how to improve your coaching and cueing abilities.

By reviewing this simplified process of obtaining a client’s health history and physician release, designing an exercise routine with modified exercises, and providing exercises for paid clients versus general members, NSCA-CPTs can be confident prescribing a routine for those who suffer from chronic or temporary health issues.

When William Kraemer first entered the field, strength and conditioning was, as he puts it, “primordial.” There were few standards, limited research, and little shared understanding. As one of the most influential figures in strength and conditioning, Kraemer recounts how the profession grew from humble beginnings into a science-driven discipline. That history still holds weight for coaches today. He explains why coaches are often drawn to new ideas, but progress comes from building on proven principles. Workout logs are central to his approach, and he notes how analyzing training over time can improve decision-making. He also emphasizes alignment across the performance ladder to support innovation and athlete development. As the Senior Advisor for Sports Performance and Sports Science at The Ohio State University, he shares his perspective on where the field is headed next. Apply his wisdom to stay grounded in solid principles, evaluate training with greater precision, and better serve your athletes.
