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.

Choose your path with new 2026 NSCA Performance Summits on March 28, 2026. Join us at one of four specialized strength and conditioning events across the U.S. and earn 0.8 CEUs.

The strength and conditioning profession involves combined competencies for the application of sport/exercise science, administration, management, teaching, and coaching. Its professionals must also comply with various laws and regulations while responding to instances of potential injury, and related claims and suits. This creates remarkable challenges, and requires substantial experience, expertise, and other resources to effectively address them, especially in multi-sport (e.g., collegiate and scholastic) settings.

The American College of Sports Medicine (ACSM) 63rd Annual Meeting was held in Boston, MA, May 31 – June 4, 2016. The number of TSAC presentations continued to increase, compared to the last few years, when the Federal Government sequester severely affected attendance.

This article explains what rotational suspension bodyweight training is and how it is different from traditional suspension bodyweight training.

This article discusses how first responder organizations can optimize their training programs through scientific techniques, including the measurement of training load.

A physical assessment continues to be one of the best ways to evaluate and measure physical preparedness and readiness of a military unit for job-related tasks and future missions. Tactical facilitators must consider multiple factors when developing testing protocols and programs, including leadership support, limited resources, and training cycle time constraints.

This article will explore the wide-ranging benefits of photobiomodulation therapy (PBM), specifically in the context of NCAA athletes, and how it has the potential to become a vital tool.

Deloading is widespread, but its application is often inconsistent and undervalued. That gap caught Lee Bell’s attention after discovering there was no consensus definition. Bell is a Senior Lecturer at Sheffield Hallam University who focuses on the deloading, overtraining, and overreaching spectrum. He explains how overtraining and overreaching are sometimes used synonymously. That confusion is compounded further by associations with overtraining syndrome (OTS). Instead, Bell frames overreaching as a “window of opportunity” when used intentionally. For example, a planned overreach can be functional or non-functional based on recovery. Bell also examines opportunities and tradeoffs in modern periodization models. He contrasts flexible and fluid approaches with more traditional, rigid programming; each approach has implications for athlete trust and recovery. Looking ahead, Bell envisions a collaborative approach to sport science driven by coaching needs. He reflects on recent coaching survey data and the key themes that emerged for the future. Hear his perspective on next steps in velocity-based training, individualized periodization, and variability.
