Exercise Order - Principles For Sequencing A Training Session

Given that you are able to select a handful of exercises that have a good chance of influencing strength & conditioning performance measures in athletes, you must be able to sequence each training session with the exercises in the “correct” order. 

I say the word “correct” very cautiously as there are no absolute truths or right or wrong in the complex, unpredictable world of human performance. To navigate through the unpredictable nature of training, it pays off greatly to have a set of principles to prescribe and coach by, while still leaving room for flexibility when new information or new prioritizations arise.

Principles for sequencing a training session

The main goal of exercise sequencing when training athletic qualities concurrently (plyometric ability, rate of force development, maximum force output, muscular endurance, etc ) is to optimize the training adaptations from each single modality and reduce the detrimental effects of neuromuscular fatigue.

Optimizing exercise order is driven by two interrelated principles: fatigability and priority. 

Fatigability

The principle of fatigability accounts for each exercise modality’s sensitivity to neuromuscular fatigue. Exercises that require high nervous system output and higher physiological and psychological readiness are more susceptible to performance detriments due to fatigue.

One explanation for this lie in the physiological characteristics of our muscle fibers. Fast-twitch, type 2 muscle fibers possess higher contractile speeds and a higher potential to produce contractile force. For this reason, they are favored during exercises that demand high-velocities and high-force outputs. Type 1 muscle fibers in contrast, are more resistant to fatigue due to their higher oxidative properties but as a consequence, have lower force-producing capabilities.

The larger velocity and force demands, the shorter they can be sustained for.

Following the principle of fatigability, exercises modalities like plyometrics, ballistic and maximum strength should then be performed first if they are to be trained concurrently within a training session. 

Accessory exercises that are single-joint in nature, aimed at smaller muscles groups can be placed in the latter half of a training session. Their relatively low technical and neuromuscular demands means their effectiveness will not be diminished to the same degree with the onset of fatigue.

Priority

The principle of priority is highly correlated to the principle of fatigue, and states that an athlete should be performing the exercises that are most important to their primary training goal, at a time when they have the most resources to do so. From an energetic and fatigue standpoint, this usually means the beginning of a training session when the athletes are at their highest point of psychological and physiological readiness (after a proper warm-up of course).

Not including the athletes at the ends of the endurance-strength spectrum (like endurance cyclists and powerlifters) the primary goal of many athletes is to develop higher rate of force development (RFD) / power and transfer this improved athleticism to sport-specific skills. Strength training is a secondary goal but must also be considered as it is crucial for second order effects such as injury risk reduction, slower-velocity force production and carryover to RFD training.

If your primary goal however, is to develop maximum strength, heavy compound lifts should come before high-velocity training. This sequencing does not follow the principle of fatigability, but satisfies the principle of prioritization. 

the contrast training exception

Contrast training offers an exception to the principles of fatigability and priority, where heavy compound lifts are deliberately performed first to elicit a post-activation-potentiation (PAP) effect, even if RFD/power is the primary goal.

PAP is a physiological/neurological phenomenon where RDF/power is increased due to previous near-maximal muscle contractions. You’ve probably seen protocols utilized by strength & conditioning coaches such as heavy back squats paired with sprinting and jumping, or heavy presses paired with ballistic medicine ball throws and slams.

While the most common form of potentiating modality is maximum strength (85-100% of 1RM or <0.5m/s bar speed if you’re using VBT), I, along with other coaches I’ve communicated with, have had success using strength-speed exercises as a potentiating modality. Exercises like weighted trapbar jumps or Olympic weightlifting variations, loaded to achieve velocities around 0.75 - 1.0m/s.

Isolating Before Integrating in Rehabilitation & Return-To-Play settings

In the context of rehabilitation, priority is given to exercises that are aimed towards rebuilding the capacity of the injured muscle, joint, tendons and/or ligaments. In my return-to-play protocols for my athletes, I will place single-joint, stability and balance-based exercises in the beginning of the training session before integrating them back into strength and plyometric exercise regressions.

Since our main goal is rebuilding the athletes’ capacities, velocities and force-outputs are not expected to be high, therefore there will be little detrimental effects to placing those exercises last.

Anecdotally, my athlete’s have reported feeling more confident in performing strength and plyometric exercises after an extended warm up and emphasis on their injured area.

Wrapping it up

Exercise sequencing should be individualized on an athlete-by-athlete basis using the principles of fatigability and priority, while taking into account special circumstances like performing advanced training protocols or managing injured athletes. While some can argue exercise selection has a larger impact influencing performance outcomes and that exercise order is of less importance, using principles for exercise sequencing bring a consistent and strategic approach to the design and implementation of a training session that cannot be overlooked by high performance athletes and coaches.

Physiological Basis Recap

In the first part of the series, we discussed the 3 paradigms used in training periodization: General adaptation syndrome by Hans Selye, Stimulus-Fatigue-Recovery-Adaptation Model, and the Fitness-Fatigue Model.

Taken from BretConteras.com Example of the SFRA (or SRA) curve in the context of muscle hypertrophy.

To recap, training volume and intensity (stimulus) has to be great enough in order to disrupt homeostasis in an athlete. Through adequate recovery, the athlete will adapt to the training, growing fitter and stronger than pre-training levels. As an athlete progresses, they begin to experience diminishing returns. A training load that once resulted in performance increases, will no longer stimulate the same degree of adaptation. To further improve performance, the stimulus has to gradually increase, in the form of higher volumes, or higher intensities (among other variables); this is the principle of progressive overload. However, some physical qualities can only be progressively overloaded to a certain degree before it is impractical to perform or may be impossible to recover from. When do we stop loading the bar with more weight? When do we stop running more miles? When do we switch exercises?

This next part will cover the concepts of training variation, and the sequential development of physical/motor abilities, 2 key concepts that training periodization is based on.

Training Variation - The Need For Varied Stimuli

We always hear trainers and coaches say: "beginners can literally do anything and they will get better". Why is this?

In young athletes or athletes with a low training age, training adaptations can be achieved with relatively small amounts of volume load and variation. A wide variety of physical attributes like strength, endurance and coordination can all be trained simultaneously with limited interference because the functional limits of those systems have not been met (low start point). 

At the intermediate and especially the elite level, there is a need for more strategic planning of training stimuli in order to achieve the gains we want to see. High-intensity training required to induce anaerobic adaptations and other top-end adaptations such as speed and rate of force development in advanced-level athletes can only be performed for a certain amount of time before overtraining symptoms begin to appear. A study looking at training intensity and volume in elite endurance athletes found that adding extra sprint or high-intensity days to already-well-trained athletes resulted in little to no improvement in performance variables. This is does not mean high-intensity training doesn't work. This means extra intensification of already-intense training programs yields no improvements, the recovery costs outweigh the benefits. More is not always better. These elite endurance athletes actually performed better when varying their training stimulus by performing low to medium intensity work while strategically performing high-intensity training when and where it counts.

Training monotony, or lack of variation, can lead to increased risk of overtraining, higher risk of injury as well as poor performance. Including the right amount variation in a training program can result in better performance measures, less risk of overuse injuries and a healthier mental state for athletes and trainees. Why do I say "the right amount of variation"? Because if a training program includes too much variations, energy and time is spent on too many different physical attributes and skills, watering down the progress and  improvements that could be made on the more crucial components of performance. If there is too little variation, athletes will experience the detrimental affects of training monotony. 

This is the same reason why powerlifters don't lift exclusively lift in the 1-3 rep range, and why sprinters don't exclusively run 100m every practice. There are benefits to varying your training stimulus - manipulating variables like exercise selection, intensity, volume, movement patterns, etc. In layman's terms: We can't do the same thing all year-round. So what do we do when we're not practicing the competitive movements? How much variation should a training program?

This all depends on the level of athlete, type of athlete, training age, the sport itself, amongst other factors. Different periodization models have their own way of undulating variation, but they all share a common trait: physical attributes and performance measures are developed in a general to specific fashion.

The general - specific continuum

Training stimuli can be categorized into general and specific. Specific qualities are movements, mental states and physical attributes that are seen in the sport the athlete is preparing for, while general qualities are defined as variation of sport-specific attributes that build the base that allows specific qualities to flourish in the long term. Diving further into the details, general and specific qualities can also be divided into: general preparatory exercises (GPE), specific preparatory exercises (SPE), specific developmental exercises (SDE) and competitive exercises (CE). The graphic below outlines the definitions of each classification of exercises and how they play a role in training. It was created by the famous sport scientist Dr. Bondarchuk and is still used as a form of exercise classification in many elite sports today.

Dr. Anatoliy Bondarchuk's Classification of Exercises

Exercise Classification Examples

Using the Bondarchuk exercise classification system, let's create a list of exercises ranging from general to specific for:

1. A Competitive Powerlifter looking to improve their COMPETITION SQUAT; and

2. An MMA Fighter preparing for a fight.

1. POWERLIFTER - COMPETITION SQUAT

Prowler Push - Example of a SPE for a Powerlifter.

General Preparatory Exercise (GPE) - Endurance cycling (or any endurance modality)
Cycling does not imitate the competitive movement (squat), however is used as an all-purpose exercise to develop lower body endurance and promotes recovery.

Specific Preparatory Exercise (SPE) - Prowler Push
The prowler push does not imitate the squat, but uses the same muscle groups (quadriceps, glutes, core) as the squat and can be used to build general work capacity and lower body strength.

Specific Development Exercises (SDE) - Pause Squats For 3-6 reps
The pause squat mimicks the competition squat position but puts more emphasis on the bottom position of the squat. This exercise is specific but is still not considered the competitive movement itself.

Competitive Movement (CE) - Competition Squat for 1-3 reps
The competition squat is exactly what you should be training to directly improve your powerlifting squat performance. The intensity is high enough to mimick the demands of a powerlifting meet 90-100% of 1RM and the movement type and bar position is exactly what is seen in a competition.

2. MMA ATHLETE - FIGHT PREPARATION

GSP performing a barbell snatch - an exercise that can fall under SPE.

General Preparatory Exercise (GPE) - Road work/Running (or any endurance modality)
Running does not imitate the competition movements (striking/grappling/movement) however, is a great tool to build base endurance. An athlete can also use a ergo rower or bike to further promote recovery by avoiding the eccentric actions and muscle damage that comes from TOO much running.

Specific Preparatory Exercise (SPE) - Plyometric Drills (for striking) & Zercher Squats (for grappling)
Plyometric drills like depth jumps or continuous medicine ball slams/throws increase rate of force development/power as well as increases core stiffness and elastic energy transfer needed to improve striking power. While strength exercises like Zercher squats improves maximal lower body and core strength to increase grappling-specific strength.

Specific Developmental Exercises (SDE) - Heavy bag work/Isolated Striking Sparing & Grappling Dummy/BJJ Rolling
These exercises consist of pieces seen in the competitive setting (MMA fight) but developed in isolation. Striking classes or grappling sessions are where fighters hone in their skills in each martial arts discipline.

Competitive Exercise (CE) - Live Full Contact MMA Sparring (5 minute rounds)
Live full contact sparring is the closest a fighter can get to imitating the competitive event itself. Here, a fighter pieces each martial arts discipline together to make it flow and to practice any fight strategies that will be employed on fight night.

As you can see, even movements that don't resemble the competition event can be included into a training program and provide performance benefits. The Bondarchuk exercise classification system is an example of the general to specific continuum paradigm as it relates to exercise selection. The same paradigm can be applied to:

• Intensity (For an Olympic lifter, sets of 10 reps @ 65% of 1RM is considered "general" while sets of 1-2 reps @ 90-100% of 1RM is considered "specific"

• Volume (For a Triathlete, 1km interval sprints is considered "general" while a 20km long-distance run can be considered more "specific")

• Rest Intervals (For a Bodybuilder, 5 min rests can be useful for improving strength and is considered "general", while 2 min rest times is better for maintaining a pump and increase metabolic stress - considered "specific").

• etc...

Overly-specific

In a NSCA seminar on periodization, coach Nick Winkleman argued that there is an uprising of overly-specific, "functional" training methods where some coaches believe that only exercises that resembles sport-specific movements will increase improvement. An example of this is the infamous ladder drills that field-based athletes love to perform.

Some coaches mistakenly believe that doing copious amounts of agility ladder drills will improve the in-game footwork of their athletes. These predetermined agility drills create unrealistic footwork that often have a poor transfer over to the sport itself. While they should not be completely avoided, these agility drills must be carefully prescribed.

Sequential development of physical attributes

In line to the general-to-specific paradigm, the concept of periodization is also based on the fact that various physical attributes are better developed in a sequential manner. Aerobic characteristics are thought to be better developed before anaerobic ones in endurance training, while muscle hypertrophy is thought to be developed prior to strength and power acquisition. 

Let's use the concept of sequential development and the general-to-specific paradigm for improving sprint performance in an Olympic sprinter:

A front squat or hip thrust can be used as a general movement to develop maximal strength, which will set the base and carry over to more specialized movements like a hang clean or trap bar jump to develop explosive strength. This explosive strength can then be used to develop more sport-specific movements such as assisted or resisted-sprint acceleration drills. This sequential development of exercise selection is suggested to be more beneficial than using acceleration drills alone, or solely using front squats or hip thrusts to improve sprint performance. Again, by performing a variation of strategically-picked general developmental exercises, we widen the base of the athlete to allow more specific qualities to flourish in the long term or on competition date.

Concluding thoughts on variation and sequential development

The time or phases spent developing each attribute in the sequential hierarchy or the amount of variation included in a training plan is what differentiates one periodization model from another. How much time should be be spent on building muscle mass if maximal power output is the goal? Should a powerlifter train the squat, bench, deadlift all the time with a high frequency (ex: Sheiko) or should they use a wide variety of accessories to target weak muscles or weak points (ex: Westside Method). Training periodization and planning has a lot of grey areas; these are ongoing debates sports scientists and coaches have on a daily basis.Read Part 101: IntroductionRead Part 201: Training Variation Read Part 202: Training Effect & PhasesRead Part 301: Review of Periodization ModelsRead Part 401: The Complexities and Problems of Periodization Theory
