Various aspects of resistance training, such as specific exercises chosen, workout structure, resistance used, volume (repetitions and sets), rest intervals between sets, and training frequency, can be manipulated to mold the strength training program to best meet an endurance athlete’s goals.

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.

Live high/train low: what changes can be expected, what dose is required, and is it preferable to other training models for improving performance in endurance sports such as running, swimming, and cycling?

Ultra-endurance performance is likely determined by quality of physical preparation, effective nutritional management, ability to cope with the environmental stressors, psychological resilience, and recovery capacity.

This book excerpt from Developing Endurance goes over nutritional strategies for pre-competition and during competition phases to maximize performance.

The goal of this article is to define some of the basic physiological responses to acute and chronic altitude exposure and to provide some evidence-based, practical guidelines when approaching training and racing at higher altitudes.

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.

A sound year-round aerobic endurance training program should be divided into sport seasons with specific goals and objectives designed to improve performance gradually and progressively.
