Strength for triathletes: how Joe Friel integrates resistance training and neuromuscular work

Endurance training is usually associated mainly with cardiorespiratory fitness. In chapter 13, Friel expands on this view by highlighting the muscles and nervous system involved in producing movement.

Strength appears as one of the model's basic abilities. The chapter's challenge is to explain how to develop and preserve it within a program that already contains three sports.

The Neuromuscular Component

Friel presents force production as a result of the relationship between muscles and the nervous system. The discussion goes beyond muscle size and includes activation, coordination, and organization of movement.

This perspective connects to the technical chapter: repeating movements and producing force properly contribute to the ability to move better.

The author also relates neuromuscular work to economy. Within his framework, improving force production can contribute to performance when the stimulus is related to the athlete's needs.

The emphasis does not eliminate the importance of endurance. The chapter seeks to integrate them according to individual characteristics and the intended race.

Who Needs to Develop This Ability?

The book acknowledges that athletes come to triathlon with different backgrounds. Those coming from strength sports may have different needs than those who have this ability underdeveloped.

Friel discusses general trends associated with profiles, age, and history, but emphasizes that the individual response remains relevant. Being in a certain category alone does not determine the choice of training.

The question follows the concept of a limiter: in which sport is strength most interfering with the current goal? This analysis helps prevent the athlete from adding all available options without setting a priority.

Strength Training, Plyometrics, and Specific Alternatives

The chapter brings together three main paths. Strength training uses external resistance to develop force. Plyometrics involve fast, explosive movements, with an emphasis on their relationship to running. Specific alternatives insert targeted efforts within swimming, cycling, and running.

Friel describes possibilities for combining these resources or selecting those most related to the limiter. They are not presented as a list that must be fully executed.

Specific work also does not eliminate the need for technique. In swimming, for example, the author again highlights learning the movement when it still represents a significant difficulty.

This article summarizes the function of these categories without reproducing the loads, sets, repetitions, or sequences illustrated in the chapter.

Progression Before Maximal Effort

The book insists on caution when introducing strength training and plyometrics. Friel links many of the difficulties to the rush to increase dose and frequency before adaptation.

The logic follows the rest of the book: the desire to improve does not instantly change current ability. Starting a new stimulus requires considering what the athlete is already doing and how the new demand modifies the whole.

The chapter presents ways to define loads and discusses the limitations of maximal tests. Its technical content depends on execution and context, which is why the protocols are not transformed here into a generic gym routine.

Strength is Also Periodized

Friel organizes the work into phases: anatomical adaptation, transition to heavier loads, maximum strength development, and maintenance. Each phase has a function within the season.

In the beginning, the athlete becomes familiar with the exercises and builds the foundation to withstand the subsequent work. Afterward, the program progresses in a targeted manner. When sport-specific preparation begins to take up more space, the goal may shift to preserving gains.

The author highlights the beginning of the season as an opportunity to invest more in this component. Later on, he uses reduced maintenance sessions in his plan.

The transition to maintenance does not mean that strength is no longer important. It means adjusting the investment to the remaining priorities.

Core and Force Transfer

The book also addresses the trunk musculature, seeking to broaden the understanding of core beyond the abdominals. Friel discusses stabilization and force transfer between parts of the body.

The interest lies in the relationship between support and movement. Trunk exercises appear as part of the preparation, connected to what the athlete needs to perform in the sports.

The chapter presents illustrated examples and forms of assessment. In this summary, we preserve the described function without inferring the cause of a difficulty or injury from an isolated visual cue.

Fitting It In with Swimming, Cycling, and Running

Strength work consumes time and generates fatigue. Friel discusses the order of sessions and the need to prevent the neuromuscular component from hindering priority tasks or technical learning.

The combination of stimuli is treated as a matter of planning. A useful exercise in isolation can be poorly placed in the week if it compromises what the athlete most needs to develop.

Therefore, the chapter returns to the limiters and the phase of the season. The goal is to select a manageable combination, rather than simply adding strength training, plyometrics, and all the specific alternatives.

Editorial example: the hidden load of strength training

An athlete maintains the three sports and adds intense gym sessions without reducing or reorganizing the rest. Later, they realize they are repeatedly arriving tired to important workouts.

In the editorial example, the issue is not solved simply by asking if strength is useful. It is necessary to evaluate how it was introduced and how it relates to the program.

The chapter's contribution is to place neuromuscular training within the same logic of purpose, progression, and recovery that guides the rest of the book.
