In the world of athletic performance, the ability to change direction quickly is often treated as a simple stop-and-go proposition. However, veteran coaches Chris Korfist and Dan Fichter argue that true agility goes far beyond a mechanical deceleration followed by a burst of acceleration. In a recent discussion on The Fast Lane, the two coaches broke down how foot strength, joint-angle-specific isometrics, visual inhibition, and reactive decision-making fundamentally shape superior change-of-direction mechanics.
By analyzing differences between elite and high school athletes, Korfist and Fichter highlighted the complex interplay between physical positioning and cognitive processing, offering a fresh perspective on how coaches should evaluate and train movement on the field.
Moving Beyond the Stop-and-Go Pattern
Traditionally, change of direction has been coached as a linear sequence: decelerate, plant, and reaccelerate in a new direction. Fichter, however, emphasizes that this traditional drill-based approach often fails to prepare athletes for the chaotic demands of actual competition. Instead, he advocates for an integrated methodology that incorporates foot strength, joint-angle-specific isometrics, visual inhibition, and the cognitive ability to respond dynamically to external cues.
The foundation of Fichter’s approach begins with isometrics. Rather than merely having athletes hold a static position, he places them in the exact joint angles and foot placements they will need to control during a high-speed cut. Once the athlete is in position, the goal is to produce and absorb force against those angles.
"Create the change that you want and get in that position and create force against it," Fichter explains.
Korfist echoes this sentiment, noting that the foot must be versatile enough to adapt to varying angles; otherwise, the rest of the kinematic chain will compensate. This introduces a fundamental coaching imperative: an athlete must be able to own a specific position before introducing a reactionary or high-velocity cue. Both coaches have utilized specialized tools like the Topro for midfoot work, combining it with isometric holds and visual tasks. However, they are quick to clarify that their methods reflect their own training environments rather than suggesting a universal piece of equipment is mandatory for every program.
Observing How Athletes Lower the Center of Mass
A major catalyst for Korfist’s recent insights came from a comparative video analysis. By reviewing footage from an NFL camp alongside high school athletic sessions, Korfist noticed a stark contrast in how athletes lower their center of mass when preparing to cut.
In his observations, high school athletes frequently lowered their chest by flexing at the spine, resulting in a distinct torso collapse. In contrast, elite athletes accomplished the same drop in height primarily through knee and ankle flexion, keeping their upper body entirely stable.
"Their knees and ankles did everything and they didn’t change their torso position at all," Korfist notes regarding the elite group.
While this comparison stems from qualitative observations of specific footage rather than a universal diagnostic standard, it provides coaches with a valuable visual benchmark. It highlights what trainers should look for on video and test during practical sessions—specifically, whether an athlete can lower their center of gravity without compromising upper-body posture.
Adding Horizontal Loading Without Losing Torso Control
To address torso stability during directional changes, Korfist utilizes a resisted isometric and rebound progression. Using equipment such as a 1080 Cable or Quantum system, he has athletes pull through their hands while keeping their shoulders down. For coaches working without advanced technology, Korfist also demonstrates a band-based alternative anchored to a rack.
The core objective of these variations is to support the torso so that the primary drivers of lateral force—the hips, knees, and ankles—can operate efficiently.
"To change direction, that’s mostly a horizontal issue," Korfist points out.
In his preferred setup using the 1080 device, the cable remains nearly stationary. The athlete pulls from a low-position handle for approximately two seconds, engaging the obliques to stabilize the torso while the lower extremities alter the height of the hips. When utilizing the band variation, Korfist places heavy emphasis on keeping the shoulders down to prevent the athlete from shrugging or folding forward.
Furthermore, Korfist highlights the importance of managing velocity windows during these drills. If an athlete exits a plant with too little speed, they risk standing upright or losing momentum; conversely, too much velocity can outpace their physical capacity to catch and control the next position.
Training a Decision, Not Just a Pattern
Physical mechanics alone are rarely enough to survive the unpredictable nature of sport. To bridge the gap between closed-drill mastery and open-field agility, Fichter incorporates dynamic tag games that force athletes to read an opponent’s movement, take an adaptive step, change direction, and reach out to make a tag.
Additionally, Fichter utilizes anti-saccades and external auditory cues—such as metronome pacing—to introduce timing demands and cognitive inhibition. Similarly, Korfist incorporates infinity runs and the GOAT drill. The underlying consensus between both coaches is that a perfectly planned cone drill cannot replicate the complex visual, balance, and timing demands required during a game.
Fichter organizes these reactive tasks around three core pillars: maintaining balance in the direction of force, engaging the visual system, and processing proprioceptive feedback. Whether an athlete is subjected to sudden physical perturbations or shifting visual information, the ultimate test is whether they can preserve or rapidly recover their balance. By introducing challenges like reaching for flags while sprinting, coaches force athletes to solve multiple physical and perceptual problems simultaneously, effectively tying isolated mechanical positions to real-time decision-making.
Evaluating the Essential Qualities of Agility
Ultimately, Korfist and Fichter’s shared insights suggest that superior change of direction is the product of multiple interacting variables. These include a resilient foot capable of managing shear forces, strength across specific joint angles, dynamic balance, sharp visual processing, and the capacity to react instantaneously.
Fichter warns that repeatedly rehearsing a sterile stop-and-go pattern leaves athletes ill-equipped to process sudden environmental cues and reorganize their bodies on the fly. Korfist reinforces this by emphasizing the critical role of upper-body behavior when dropping the center of mass. While their conversations provide coaches with actionable frameworks for observation and testing, they emphasize that agility cannot be reduced to a single metric or a one-size-fits-all drill.
