At The U of Strength, we have the opportunity to coach athletes from a wide variety of sports, ages, and skill levels. Because of that, we believe it is essential to have an expansive resistance training toolbox.
One concept that often gets misunderstood in strength and conditioning is the use of partial range of motion (ROM) exercises. For years, many coaches have adopted an "ass-to-grass" mentality, believing that every movement must be performed through the greatest range of motion possible. While full ROM training absolutely has tremendous value, completely dismissing partial movements means leaving a valuable tool unused. The reality is that full and partial ROM exercises are not competing methods. They are complementary strategies that can be used together to improve athletic preparation. The question shouldn't be: “Which one is better?" Instead, it should be: "When is each tool most appropriate?" When applied effectively, partial range movements can provide unique benefits that support an athlete's long-term development and performance. 1. Reduce Overall Stress During Peaking & In-Season Training As competition approaches, the goal often shifts from building new qualities to maintaining performance while managing fatigue. Partial ROM exercises allow athletes to continue exposing the neuromuscular system to meaningful loads while reducing overall mechanical and physiological stress. This can be especially valuable during:
The athlete stays strong and explosive without accumulating unnecessary fatigue that may interfere with performance. 2. Complement Full Range of Motion Training Partial movements should not replace full ROM exercises. Instead, they can fill gaps that full ROM movements may not address. The combination often creates a more complete training stimulus than relying on either strategy alone. 3. Allow for Greater Force & Velocity Outputs Because the movement distance is reduced, athletes can often produce higher force outputs or move loads at greater velocities. This can be useful when targeting specific adaptations such as:
The ability to handle heavier loads or move more aggressively through a specific range can create a unique stimulus that may not be achievable through full ROM exercises alone. 4. Increase Variability in the Weight Room Athletes thrive when they are exposed to a wide range of movement experiences. One of our goals is to continually expand an athlete's training menu rather than limit them to a narrow set of exercises. Partial ROM variations provide another way to create:
More variability doesn't mean randomness. It means providing athletes with a broader set of experiences that may enhance their adaptability over time. 5. Increase Specificity Sport rarely demands force production through identical ranges of motion every time. Athletes often need to express force from different joint positions and body shapes. Partial movements can help accentuate these positions by allowing coaches to emphasize:
This allows training to become more targeted without abandoning the benefits of full ROM strength development. The Takeaway Full range of motion training remains an important foundation for athletic development. But dismissing partial movements simply because they don't travel through a complete range ignores the value they can provide. We don't view training methods as competing ideologies. We view them as tools. The best coaches aren't married to one method. They understand the strengths and limitations of each option and apply them when appropriate. Full ROM and partial ROM training both have a place in athletic preparation. When combined intelligently, they can help athletes manage fatigue, develop force capabilities, expand movement solutions, and prepare for the specific demands of sport.

6/1/2026 Beyond Performance: Training Across the Force-Velocity Continuum to Build Robust Motor PatternsRead NowThe complex and contrast methods are traditionally viewed as strategies for improving performance. Heavy resistance exercises are paired with explosive, high-velocity actions to enhance power output, rate of force development (RFD), and overall athletic explosiveness. While these outcomes are well established, what often goes overlooked is the role these methods can play in developing more adaptable and robust motor patterns.
When thoughtfully designed, complex and contrast training becomes more than a way to increase outputs. It becomes a learning environment. By manipulating load, speed, rhythm, direction, and setup, athletes are exposed to a broad range of force and velocity demands. Instead of rehearsing a single “ideal” movement solution, they learn to organize and reorganize movement under changing constraints. Over time, this expands the athlete’s movement toolbox and strengthens the adaptability of their coordination strategies. Complex + Contrast as a Learning Tool In our training process, we’ve found tremendous value in combining complex and contrast methods. Traditionally, these pairings rely on post-activation potentiation (PAP), where a heavy resistance exercise temporarily enhances the nervous system’s ability to produce force and speed in the subsequent movement. The performance benefits are obvious:
But there is another layer that deserves attention. As athletes transition between high-force and high-velocity tasks, they are forced to solve new movement problems. The body must continuously recalibrate timing, stiffness, coordination, and force application strategies based on the demands of the task. This creates an important dual effect:
Rather than viewing contrast training strictly through the lens of physiology, it can also be viewed through the lens of skill acquisition and coordination development. Working Across the Force-Velocity Continuum The guiding principle behind our design is simple: Expose athletes to the full force-velocity continuum. Instead of living exclusively in high-force or high-speed environments, athletes learn to express force across multiple velocities and movement conditions. A typical progression may move from:
As speed increases, coordination demands shift. Ground contact strategies change. Timing changes. Shape organization changes. The athlete must continuously self-organize to solve the task effectively. This variability is important. A Practical Example Sequence A session built around complex and contrast principles may look something like this: 1. Squat, Deadlift, or Pressing Variations Purpose: High-load strength work primes the neuromuscular system while emphasizing force production and structural organization. At this end of the continuum, athletes experience:
These movements establish the force foundation that later explosive actions can build from. 2. Single-Response Jump & Throw Patterns Purpose: Transition toward higher-velocity outputs while maintaining high intent and force generation. Examples may include:
These movements begin bridging the gap between maximal force production and rapid force development. 3. Multi-Response Plyometrics Purpose: Challenge athletes to rapidly reorganize force production through elastic strategies. Examples may include:
Now the athlete must solve increasingly dynamic movement problems with less available time. The system shifts toward faster elastic behavior and coordination. 4. Accelerated Plyometrics Purpose: Create overspeed conditions that expose athletes to extremely high movement velocities and rapid force exchange. Examples may include:
These environments challenge the nervous system to coordinate movement at speeds often unavailable during normal training conditions. More Than Just Performance Metrics Too often, training conversations revolve solely around outputs:
While these metrics are valuable, they only tell part of the story. The deeper adaptation may be the athlete’s growing ability to coordinate movement effectively across changing demands. By working across the force-velocity continuum, athletes learn to:
This is especially important in sport, where athletes rarely encounter perfectly predictable situations. Training for Adaptability The goal is not to create athletes who can only perform well in controlled settings. The goal is to build athletes who can adapt. Complex and contrast methods help accomplish this because they expose the athlete to:
Every variation becomes an opportunity for exploration and self-organization. Instead of chasing a single “perfect” technique, athletes learn how to stabilize performance across many conditions. That is ultimately what robust motor behavior looks like. Beyond Peak Output Complex and contrast training should be viewed as more than performance enhancement tools. When integrated with thoughtful design, they become powerful environments for motor learning and coordination development. Yes, athletes may jump higher, sprint faster, or throw harder. But more importantly, they learn how to organize movement across a wide spectrum of demands. They develop motor systems that are more adaptable, resilient, and capable of holding up under fatigue, pressure, and unpredictability. By blending high-force and high-velocity methods across the continuum, coaches can provide athletes with the dual benefit of maximizing performance outputs while simultaneously strengthening the foundation of how those outputs are produced. When managing a training program, one of the most important, and often overlooked, considerations is how the foot interacts with the ground. Every sprint, jump, cut, and change of direction begins with this interaction. The quality of that connection influences how effectively an athlete can control their center of gravity, organize force, and express movement.
The foot is far more than a simple contact point. It’s a dynamic sensory and mechanical system that constantly receives information from the environment while simultaneously transmitting force back into the ground. How the body organizes around that system determines movement quality, balance, rhythm, and ultimately athletic performance. For this reason, developing propulsion is not simply about making athletes stronger. It’s about teaching them how to interact with the ground more effectively. Understanding the Rhythm of Propulsion During gait and athletic movement, propulsion unfolds through a sequence of coordinated stages. Each stage reflects how different regions of the foot interact with the ground to accept, manage, and redirect force through the body. These stages are commonly described as:
Together, they create the natural rhythm of movement, a cycle of yielding, producing, and releasing energy. Rather than viewing movement as isolated muscular actions, this perspective emphasizes how the entire system coordinates around ground interaction. Each stage contributes to the athlete’s ability to move efficiently, maintain balance, and transition seamlessly from one action to the next. When one stage is poorly organized, force leaks occur. Timing becomes inconsistent. Movement efficiency decreases. Over time, athletes may compensate with excessive stiffness, poor sequencing, or inefficient strategies that limit performance. Training these phases intentionally gives athletes access to more adaptable and effective movement solutions. The Three Stages of Propulsion 1. Early Phase — Force Acceptance & Initiation The early phase begins the moment the athlete contacts the ground. At this stage, the body transitions from yielding, accepting force, into organizing for propulsion. This phase is often overlooked because it appears subtle. However, it lays the foundation for everything that follows. If an athlete cannot organize shape and alignment during initial contact, force production later in the movement becomes compromised. Key qualities developed during this phase include:
The goal is not simply to accept force, but to organize it. Athletes who struggle here often collapse through the foot, lose trunk position, or shift excessively through the pelvis before propulsion even begins. Teaching athletes to manage this early stage improves both movement effectiveness and resilience. 2. Mid Phase — Max Force Production As the center of mass progresses over the foot, the body enters its strongest mechanical position for producing force. This is where propulsion becomes highly dependent on:
In many athletic tasks, this phase represents the athlete’s highest force-producing opportunity. The body must create enough stiffness to transmit force effectively without becoming too rigid or disconnected. Smooth athletes don’t simply push harder into the ground. They organize the body in a way that allows force to transfer through the system. This stage becomes especially important during athletic movements. The better the athlete can manage force through this stage, the more effectively they can express power. 3. Late Phase — Energy Transfer & Force Release The final phase of propulsion occurs as the athlete transitions toward toe-off and releases energy into movement. At this point, the forefoot becomes the final contact point with the ground. The body shifts from producing force to redirecting and transferring it into the next action. This phase relies heavily on:
Athletes who struggle here often appear “stuck” in the ground too long. Their movement loses rhythm, transitions become delayed, and energy transfer becomes inefficient. Effective late-phase propulsion creates smooth acceleration, fluid transitions, and dynamic movement qualities that are essential in sport. The body isn’t just pushing anymore, it’s releasing energy with precision and timing. Applying Propulsion Concepts in the Weight Room While these phases occur naturally during movement, they can also be trained intentionally within the weight room environment. One of the most versatile tools for exploring propulsion mechanics is the split squat. The split squat provides a unique opportunity because it allows coaches to manipulate:
By adjusting setup and environment, coaches can emphasize different stages of propulsion and expose athletes to specific movement problems. This transforms the split squat from a simple lower-body strength exercise into a powerful tool for teaching athletes how to organize force. Instead of merely chasing load, the athlete learns to feel:
Each variation teaches a slightly different solution. Split Squat Variations Through the Lens of Propulsion
Beyond Strength: Teaching Athletes to Interact with the Ground The split squat is often viewed purely as a unilateral strength exercise. But when examined through the lens of propulsion, it becomes much more than that. It becomes a teaching tool. A way to expose athletes to:
Rather than training muscles in isolation, we train the athlete’s relationship with the ground. This is important because sport does not happen in ideal positions. Athletes constantly transition between yielding and overcoming while adapting to changing environments. The more movement solutions they can access, the more adaptable and smooth they become. Final Thought Training propulsion isn’t simply about building stronger legs or producing more force. It’s about improving how athletes organize and transfer force through the ground. Every phase of movement depends on the interaction between the foot and the environment. The athlete who understands how to accept force, organize shape, and release energy efficiently will move with greater rhythm, balance, and intent. The split squat offers a simple yet highly adaptable framework for developing these qualities from the ground up. When programmed intentionally, it becomes more than an exercise. It becomes a staple for teaching athletes how to own their movement signature. In many traditional strength and conditioning settings, the pursuit of balance, symmetry, and perfect movement patterns reigns supreme. Programs are often built around structured progressions and predictable training parameters, intensity, volume, density, velocity, carefully controlled to produce consistent outcomes. This approach has value. It builds foundational strength, improves tissue tolerance, and establishes repeatable movement patterns.
But sport performance doesn’t unfold in controlled conditions. Competition is messy. It’s dynamic, chaotic, and unpredictable. Athletes rarely get to express force from ideal positions, at ideal speeds, or under ideal timing. They are constantly required to adapt, adjusting to opponents, space, fatigue, and rapidly changing task demands. The ability to organize force under uncertainty is often what separates resilient, adaptable performers from those who break down when conditions drift away from the “perfect rep.” That gap is where many traditional models fall short. Why We Lean into the Unorthodox During specific blocks of training, we intentionally move away from always chasing pristine mechanics and clean symmetry. Not because quality doesn’t matter, but because quality in sport looks different than quality in the weight room. Rather than prescribing every detail of how an athlete should move, we design environments that ask better questions of the system. We introduce constraints, variability, and occasionally uncomfortable scenarios that force athletes to self-organize solutions in real time. This might mean:
The goal is not to create sloppy movement. The goal is to expand the athlete’s available solutions. This approach does not replace traditional strength and conditioning methods. It complements them. Structured loading builds the base. Variability builds the edges. And it’s often at the edges where sport actually lives. Building the Edges of Movement Solutions When athletes are only exposed to symmetrical, predictable environments, they become very good at repeating rehearsed patterns. That’s useful but limited. Once the environment changes, those same athletes may struggle to adapt because they’ve never been asked to explore alternatives. By contrast, variable environments:
Instead of coaching every rep into compliance, we allow the system to search. Over time, this search process leads to more robust, adaptable movement strategies that hold up under pressure. The Power of Variability in Force Development In many models, variability is treated as noise, something to be minimized or eliminated. We see it differently. Variability is information. When used intentionally, variability becomes a powerful tool for developing force expression that is resilient, not fragile. Controlled chaos disrupts automatic patterns and prevents athletes from relying on a single, rehearsed solution. It forces deeper engagement with the task and demands continuous adjustment of shape, stiffness, and timing. From a force development standpoint, this matters because:
By challenging athletes to manage fluctuating forces, shifting bases of support, and imperfect positions, we expose weak links that wouldn’t appear in a controlled lift. The athlete isn’t just producing force, they’re organizing it. From Control to Capability This doesn’t mean abandoning standards or allowing randomness for randomness’ sake. Constraints are still carefully chosen. The environment is shaped with intent. But instead of controlling the outcome, we control the problem. Over time, athletes become:
That confidence carries over. When the game speeds up, when fatigue sets in, or when chaos is unavoidable, the athlete has already been there. Strength and conditioning isn’t just about building stronger bodies, it’s about building capable systems. Systems that can solve problems, adapt under pressure, and express force when conditions aren’t perfect. By intentionally integrating variability and unorthodox strategies at the right time, we don’t create chaos, we prepare athletes for it. And in sport, that preparation often makes all the difference. One of the biggest challenges in athletic development isn’t teaching athletes what to do, it’s helping them discover movement solutions they would never arrive at on their own. Left unchecked, the system defaults to what it already knows: familiar compensations, preferred strategies, and rehearsed patterns.
That’s where intelligent constraints matter. And one of the most powerful constraints we can introduce is asymmetrical. Why Asymmetrical? Most training environments are built around symmetry:
But human movement isn’t symmetrical, and sport certainly isn’t. Athletes cut off one leg. They rotate and turn around fixed limbs. They accept force on one side while producing it on the other. When we introduce asymmetry into training, we create space for athletes to explore new solutions. We bias internal and external rotation strategies. We expose options that often stay hidden in balanced, bilateral scenarios. Asymmetry doesn’t fix movement. It reveals possibilities. Influencing Movement Without Coaching Outcomes Rather than over-coaching technique, we manipulate constraints. Small changes in setup can dramatically change how an athlete organizes force. Here are three simple design tactics that consistently open new movement doors: 1. One Side Elevated Elevating a foot or a hand on a box or mat changes how the athlete experiences space. This often invites:
These solutions rarely show up in perfectly symmetrical positions. 2. Staggered & Split Stances Altering the base of support changes what’s available to the system. Staggered and split stances:
Compared to parallel stances, they open entirely different movement conversations. 3. Load on One Side of the Body Using ipsilateral or contralateral loads (bands, dumbbells, kettlebells) biases the system toward internal or external rotation strategies. These constraints don’t eliminate compensations. They refine and expose them, showing how the athlete adapts when symmetry is removed. That information is gold. The Bigger Picture Asymmetrical design isn’t about making exercises harder or more complex. It’s about:
Asymmetry builds adaptability. And adaptable athletes are durable athletes, capable of solving the unpredictable problems sport and life will always present. That’s the real goal. |
