This infographic highlights the use of an individualized load-velocity method to prescribe sled-push loads in young athletes.

Steve Morgan, Tactical Strength Coach with the US Army, explains modifications to the sled push for tactical populations.

This info-graphic describes research on velocity decrements to increase propulsive and horizontal force applications to increase acceleration kinetics.

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.

This article examines using the sled as a dynamic correspondence exercise for increasing on-ice acceleration.

This infographic takes a look at resisted sled training and the benefits it may have on sprint performance. It also offers insight into when and how to utilize resisted sled training.

This infographic summarizes how varying sled-loads increase different characteristics of sprint performance in male high school athletes.

Hybrid fitness competitions such as HYROX have rapidly gained popularity, blending aerobic endurance running with a variety of high-intensity resistance and ergometer-based stations in a globally standardized format. The sport’s unique structure, comprising eight 1-kilometer runs interspersed with diverse workload stations, presents distinct physiologic, biomechanical, and technical demands. This review synthesizes existing research on hybrid fitness events to identify the key determinants of HYROX performance, emphasizing aerobic capacity, anaerobic power, local muscular endurance, and maximal strength. The aerobic system is foundational, enabling recovery between high-intensity efforts and sustaining performance during the event’s prolonged duration. Conversely, anaerobic capacity is critical for executing the high-intensity efforts demanded by each fitness station. Local muscular endurance supports repeated submaximal contractions, while strength and power underpin performance in movements such as sled pushes and running economy. Technical proficiency and injury prevention strategies are also discussed, alongside targeted programming recommendations, including high-intensity interval training, circuit training, and blood flow restriction methods. Despite its growing popularity, limited sport-specific research exists, necessitating further investigation to refine training and performance strategies. This review provides a comprehensive framework for athletes and coaches to optimize preparation and performance in HYROX, contributing to the broader understanding of hybrid fitness competitions.

Lindsey Kirschman sees her non-traditional educational background as her greatest asset, not a detriment. She still considers herself a teacher — just differently — as the Director of Sports Performance for University of Utah women’s basketball. Coming from a family of educators, Kirschman initially studied forestry and range science before pursuing strength and conditioning. Kirschman explains how her teaching experience provided a firm foundation for optimizing learning and creating a positive environment. Her approach promotes skill transfer from the weight room to sport and beyond, using exercises like sled pushes as analogies for life lessons about resilience. A former track athlete, Kirschman underscores that while the finish line is the same, every athlete’s starting point is unique. Kirschman also discusses culture building through her “GOAT Award” and the challenges of transitioning from a generalist to a specialist. She encourages aspiring professionals to reframe their mindset and fully engage with their working environment.
