The path to the top is not always linear. For Jill Costanza, it included returning to school and stops in collegiate and military performance before becoming Director of Sport Science and Assistant Strength and Conditioning Coach with the National Football League (NFL) Detroit Lions. Costanza describes today’s sport science landscape as a “Wild West,” where definitions differ by perspective. Her focus centers on assessing the athlete and program effectiveness against the demands of the game to identify holistic interventions. She outlines how intentional systems, a clear communication funnel, and data visualizations help athletes and stakeholders understand the “why,” build buy-in, and tap into competitiveness. Addressing common misconceptions, Costanza clarifies that elite athletes can still have foundational qualities that need rewiring. She emphasizes movement quality, proprioception, and breathing while adapting for individual needs and neurological fatigue. Learn how to build sport science systems, turn insights into action, and keep progressing on your professional path.

Triathlons are unique compared to other sports as athletes are required to master three distinct disciplines: swimming, cycling, and running. This article lays out a training program that focuses on a balance between strength training and sport training to avoid overtraining and overuse injuries and to maximize performance in a multi-sport athlete.

Sled exercises provide a training stimulus that closely mimics real-world physical demands of sports. This article provides examples of how to implement sled training into a program.

In recent years, youth strength training and models of athletic development have become hot topics thanks in part to a shift in youth sports from leisure activities to year-round commitments. In order for strength and conditioning professionals to help the athletes of tomorrow achieve their performance and fitness goals, it’s imperative to develop safe, effective, and balanced programming for the youth of today.

Unfortunately for many soldiers, running, pushups, and sit-ups address endurance, but do little to train mobility and strength. To meet the demands of their work and help avoid overuse injuries, a training program for soldiers should include mobility, strength, and endurance components.
