In modern athletic development, few movements are as thoroughly drilled—and perhaps as widely misunderstood—as the change of direction. For decades, coaches have relied on traditional cone drills, pre-planned agility ladders, and repetitive stop-and-go patterns to teach athletes how to decelerate, plant, and reaccelerate. However, a growing cohort of elite performance specialists argues that these sterile environments fail to capture the complex, chaotic demands of live competition.
In a recent installment of "The Fast Lane," veteran coaches Chris Korfist and Dan Fichter sat down to deconstruct the mechanics of changing direction. By comparing high-definition game footage from elite NFL settings with high school training tape, Korfist and Fichter identified stark differences in how athletes manage their center of mass, absorb horizontal forces, and process visual stimuli. Their discussion moves far beyond the traditional stop-and-start paradigm, focusing instead on a holistic approach rooted in foot strength, torso control, joint-angle-specific isometrics, and reactive decision-making.
Rethinking the Mechanics of Deceleration
For Fichter and Korfist, a true change of direction is never merely a linear stop followed immediately by a new sprint. Instead, it is an intricate ballet of force management, requiring the body to handle immense deceleration loads while maintaining structural integrity. Fichter approaches this challenge by examining foot strength, joint-angle-specific isometrics, visual inhibition, and an athlete’s capacity to respond instantly to external cues. By anchoring an athlete in the exact positions they must control during a sharp cut, Fichter emphasizes the importance of generating and resisting force within those specific windows.
"Create the change that you want and get in that position and create force against it," Fichter explains.

Complementing this perspective, Korfist focuses heavily on how athletes handle horizontal loading and torso control. Drawing from his comparative video analysis—which included four intensive days observing professional players at an NFL camp alongside footage of developing high school athletes—Korfist noticed a profound discrepancy in how different tiers of competitors lower their center of mass. High school athletes, he observed, frequently initiate a descent by bending at the spine, collapsing the chest forward and shifting their weight improperly.
In contrast, elite athletes achieve the necessary drop in their center of mass by relying almost exclusively on knee and ankle flexion while keeping their torso rigid and stable. "Their knees and ankles did everything and they didn’t change their torso position at all," Korfist notes of the professional group. While this observation stems from qualitative, real-world comparison rather than a rigid universal diagnostic rule, it provides modern strength coaches with a vital visual baseline for what to look for on film and test in training environments.
Horizontal Loading and Torso Stability
To bridge the gap between structural stability and dynamic movement, Korfist utilizes resisted isometric and rebound progressions using advanced training technology such as the 1080 Cable or Quantum system. In this setup, the cable remains nearly stationary while the athlete pulls through a hand attachment from a low position for roughly two seconds, keeping the shoulder depressed to prevent upper-body shrugging and forward folding. For coaches lacking high-end tech, Korfist also advocates for a band-based variation anchored to a standard rack, preserving the core training intent without requiring identical equipment.
The primary objective of these resisted variations is to train the obliques and surrounding core musculature to support the torso while the lower extremities solve the complex problem of lateral force management. Korfist stresses that changing direction is fundamentally a horizontal issue. However, he also warns coaches about the delicate velocity window inherent in such drills. If an athlete moves with too little speed out of a plant, they risk standing straight up or losing balance; conversely, if the velocity is excessively high, the athlete may outpace their structural ability to absorb and catch the next position cleanly.

Both coaches also emphasize midfoot training as a foundational pillar of this process, utilizing specialized tools like the Topro in their daily weight room operations to build resilient foot structures. According to Korfist, the foot must retain the capacity to adapt fluidly to varying angles upon contact; otherwise, the rest of the kinetic chain will inevitably compensate, leading to inefficient movement and potential injury risks.
Training Decisions, Not Just Movement Patterns
Perhaps the most significant limitation of traditional agility training is its predictability. In actual games, athletes rarely know precisely when or where a directional change will be required. To address this perceptual-cognitive gap, Fichter incorporates dynamic tag games that force players to read an opponent, make split-second decisions, alter their trajectory, and reach out to execute a tag.
By integrating tools like anti-saccades and external auditory cues, Fichter introduces crucial elements of timing and inhibition that are entirely absent from standard pre-planned cone drills. Korfist echoes this philosophy, pointing to dynamic movements like infinity runs and the GOAT drill as effective ways to challenge athletes. Whether it is Korfist’s use of flags that demand running and reaching simultaneously, or Fichter’s reliance on unpredictable visual cues, their training framework consistently ties isolated joint positions directly to real-time decision-making.
Data points discussed by the coaches highlight the individualized nature of their methodologies. Metrics referenced during their analysis—such as Fichter recalling a 120 beats-per-minute metronome rate from a prior balance discussion, or Korfist noting that parents observed quicker soccer movements in their children after just two training sessions—serve to illustrate everyday coaching contexts rather than rigid, universal prescriptions. Similarly, observations regarding specific cutting angles, such as knees flexing slightly deeper than 90 degrees in certain effective cuts, underscore the variability of elite movement rather than a one-size-fits-all target.

Ultimately, the insights shared by Korfist and Fichter challenge coaches to look beyond the surface of speed and agility training. By combining rigorous physical preparation—such as foot strength, targeted isometrics, and horizontal torso control—with the chaotic, unpredictable nature of visual processing and reaction time, performance specialists can better prepare athletes for the demands of competitive sport.
