Most athletes think the quadriceps are mainly about push. But the rectus femoris may contribute to more than propulsion alone. Discover how this unique two-joint muscle may help connect push, lift, and next-step speed.

RUNNING PHASES EXPLAINED: How Your Legs Move When You Run
Most athletes focus on pushing harder—but running speed depends on more than just force. This article breaks down the three phases of running—push, swing, and pull—and explains how your legs actually move during each step so you can understand what’s missing from your training and start improving your speed.
Why Running Speed May Depend On What Peaks Together
Most athletes focus on force production and the pushing leg. AQ explains why sprint speed may depend on the pushing leg, swing leg, arms, and torso reaching their greatest strength contribution together—and what happens when one contributor can no longer keep up.
Hip Flexor Muscles for Speed: What Actually Makes You Run Faster
Hip flexor muscles are one of the most overlooked factors in running speed—and often the true limiting factor. This article explains how they control stride rate and why increasing speed depends on raising strength balance across the entire system, not just pushing harder.
Why More Weight-Room Power Doesn’t Always Make You Faster
Getting stronger does not always lead to faster sprinting. AQ explains why weight-room power and sprint speed are not automatically the same thing, how athletes often misinterpret performance testing, and why identifying what is still limiting speed may be more important than chasing bigger numbers. 🚀💥
Why Running “Smooth” May Be More Than Just Good Form
Most athletes assume smooth running creates speed. AQ explains why smooth sprinting may actually be the result of better sprinting, how the pushing side and swing side influence movement quality, and why smoothness may be revealing speed rather than creating it. 🚀💥
Why Sprinting “Harder” Doesn’t Always Make You Faster
Many athletes believe running faster is simply a matter of trying harder. AQ explains why greater effort does not always create greater speed, how strain can reveal hidden limitations within the sprint system, and why identifying the real limitation may matter more than adding more effort. 🚀💥
Why Quick Feet Don’t Always Create Faster Running
Many athletes believe quick feet automatically lead to faster running. AQ explains why quick feet may be one of the most visible expressions of speed rather than its true source, and why improving sprint-system function may matter more than simply moving the feet faster. 🚀💥
Why Better Posture May Be A Result Of Better Sprinting
Many athletes try to fix sprint posture directly. AQ explains why posture may be less important as a cue and more important as a clue about what the sprint system is capable of supporting during sprinting. 🚀💥
Why Running Relaxed May Be a Result of Better Mechanics
Many athletes try to force relaxation while sprinting. AQ explains why relaxed sprinting is often an outcome of better sprint mechanics, how the body self-regulates speed, and why faster running sometimes feels lighter, smoother, and less restricted. 🚀💥
Hip Flexors for Running Speed: The Most Overlooked Muscle Group in Sprinting
Most athletes think speed comes primarily from the pushing leg. AQ explains why hip flexors may be one of the most overlooked contributors in sprinting, how they influence swing-leg aggression, step arrival, and sprint-system cycling speed, and why they can become a hidden limitation to greater speed.
Why You’re Not Getting Faster (And What Finally Changes It)
Not getting faster even though you train hard? Learn what most speed programs miss—and what actually helps you improve.
HOW TO RUN FASTER: The Complete Guide to Increasing Speed, Power, and Performance
Want to know how to run faster and finally see real results? This guide breaks down the system behind speed, explaining why strength alone isn’t enough and how improving strength balance, timing, and coordination across your entire body leads to faster, more efficient running.
Shoulder Extensor Muscles for Running Speed: The Other Half of Arm Drive
Shoulder extensors complete the arm cycle in running. Learn how backward arm movement supports balance, coordination, and speed performance.
SPEED TRAINING SCIENCE: Why Most Methods Fail (And What Actually Works)
Most athletes train hard but don’t get faster. This article explains the science behind speed training, including muscle contraction, fast twitch fibers, and why traditional methods often fail to improve speed.
Why Getting Bigger Can Actually Make You Slower (The Science Explained)
Many athletes believe getting bigger will make them faster—but that’s not always true. Learn how hypertrophy affects muscle function, contraction speed, and why size alone doesn’t translate into real performance.
Spine Rotator Muscles for Running Speed: How Rotation Connects Your Entire System
Spine rotators don’t create speed—they connect your system. Learn how rotation transfers force and improves coordination for faster running.
Why Strength Alone Won’t Make You Faster
Getting stronger doesn’t guarantee you’ll run faster. This article explains why strength alone isn’t enough—and how balance, coordination, and system efficiency determine whether your strength actually turns into speed.
What Actually Creates Force in Running? (And Why Most Athletes Get It Wrong)
Force is one of the most misunderstood aspects of running. Many athletes think strength alone creates speed, but force depends on how your system applies and transfers energy. Learn what actually creates force in running and how to improve it.
Why Faster Turnover Doesn’t Always Make You Faster (The Stride Rate Myth)
Many athletes believe faster turnover automatically creates more speed. AQ explains why stride rate is often a reflection of sprint-system function and why identifying the real limitation may matter more than simply trying to move your legs faster.
The Real Cause of Overstriding (And Why It’s Not What You Think)
Many athletes try to fix overstriding by changing where the foot lands. AQ explains why overstriding may be the visible outcome of deeper contributor limitations involving the pushing leg, swing leg, arms, torso, and strength balance.
What Influences Ground Contact Time? (And Why Quick Feet Aren’t The Answer)
Most athletes assume shorter ground contact time creates faster running. AQ explains why contact time may often be an outcome of contributor relationships already influencing the next step before the foot reaches the ground.
Does Foot Strike Matter? (Yes—But Probably Not As Much As You Think)
Does foot strike matter for running speed? AQ explains why foot strike deserves attention, but often isn’t the biggest factor limiting sprint performance.
What Influences Ground Mechanics? (And Why The Foot Isn’t Always The Source)
Ground mechanics describe how the foot interacts with the ground during running. AQ explains why the foot may be where ground mechanics become visible, while the sprint system may be what influences them.
