Duncan French explains the strength and conditioning work with MMA fighters in both their aerobic and anaerobic capacities at the UFC Performance Institute in this 2018 National Conference video.

This article provides a sample six-week, non-linear program for improving muscular strength, power, endurance, anaerobic capacity, and aerobic capacity. However, this is not a “one-size fits all” program, and manipulation of the program variables may be warranted for some individuals.

This article discusses how high-intensity interval training may be an effective metabolic training method for soldiers trying to maintain physical preparedness during deployment.

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.

Oxygen uptake (or consumption) is a measure of a person’s ability to take in oxygen and deliver it to the working tissues, and the ability of working tissues to use oxygen. During low-intensity exercise with a constant power output, oxygen uptake increases for the first few minutes until a steady state of uptake is reached.

Research shows that the appropriate integration of resistance training into the endurance athlete’s training can result in significantly better performance when compared to classic endurance training plans that focus only on aerobic endurance.

This article explains Fartlek training as well as how it can be programmed and individualized for different clients.

In this article, personal trainers and strength and conditioning coaches will learn how Football Club of Mumbaikars has worked to maintain and even improved the fitness profile of its athletes using this online training protocol, and provide a template for how to apply this protocol to the general population.

This article features the recharge skate—an in-season hockey conditioning drill, designed by the authors, to maintain hockey-specific energy system fitness throughout the competitive season.
