In sports, straight-line speed is often viewed as a purely genetic gift—you are either born fast, or you are not. However, while genetics play a role in your ceiling, running fast is ultimately a highly technical skill. Speed is a formula of stride length, stride frequency, and force application.
At Athletes Untapped, we notice that many athletes try to run faster simply by trying harder. They clench their jaws, swing their arms wildly across their body, and reach their feet as far forward as possible to take massive steps. This lack of structural mechanics leads to extreme energy leaks, heavy braking forces that destroy the hamstrings, and a painfully slow top-end speed.
The secret to outrunning the competition lies in linear speed mechanics. Proper training fixes these neuromuscular and postural issues, allowing athletes to direct 100 percent of their energy straight down the track or field, resulting in explosive acceleration and effortless maximum velocity.

Why This Skill Matters for Athlete Development
Your linear speed mechanics dictate your absolute athletic potential. Whether you are running a 40-yard dash, chasing down a fast break, or sprinting to first base, straight-line speed is the ultimate separator.
- Game Performance: Elite linear speed mechanics directly translate to arriving first. When you eliminate side-to-side rotational movements and strike the ground directly beneath your center of mass, you stop fighting your own body. This efficiency allows you to cover more ground in less time, making it significantly harder for defenders to catch you from behind.
- Confidence: I have seen athletes improve faster when they spend just 10 focused minutes on these drills at the start of every speed session. When front-side mechanics become muscle memory, players stop feeling heavy on their feet. They gain the composure to relax at top speed, trust their form, and execute a confident, blazing sprint without tensing up under pressure.
- Long-Term Development: As you progress to higher levels of competition, the game speed increases exponentially. A biomechanically sound sprinting stride protects you from the devastating non-contact soft tissue injuries (like hamstring tears) caused by over-striding and heel striking. It provides the structural foundation needed to handle immense ground reaction forces safely, ensuring your speed scales as you grow.
Best Drills / Tips / Techniques
You cannot master linear speed by simply running gasers until you vomit. You need isolated, high-quality repetitions that train the nervous system to fire correctly. Here are 5 drills AU coaches use to build terrifying straight-line speed.
1. A-Skips
How to perform it: Move forward with a rhythmic skipping motion. Aggressively drive your lead knee up to hip height with your toe pointing up (dorsiflexion). Forcefully strike the ground directly under your hips with the ball of your foot, allowing the opposite knee to instantly pop up.
Why it works: It forces the brain to internalize the concept of “front-side mechanics”—doing the work in front of the body rather than letting the leg trail behind you. It breaks the sprint stride down into its simplest component of vertical force application.
Coaching tips: The downward strike is more important than the upward lift. Think about punching the ground away from you.
Common mistakes: Skipping for distance instead of height and rhythm. The steps should be short and snappy, not long and floating.
2. Seated Arm Sprints
How to perform it: Sit flat on the ground with your legs extended straight out in front of you. Sit up perfectly tall. On a coach’s whistle, sprint with your arms as fast and aggressively as possible for 10 seconds.
Why it works: Your legs follow your arms. If your arms cross your body, your hips will twist. This drill isolates the upper body, forcing the athlete to feel the powerful, linear “cheek to cheek” (face cheek to glute cheek) trajectory required for straight-line speed.
Coaching tips: Keep your elbows locked at a rough 90-degree angle. The movement must come entirely from the shoulder joint.
Common mistakes: Shrugging the shoulders up to the ears. Keep your shoulders relaxed and pulled down to allow the arms to swing freely.
3. Wall Acceleration Posture Drills
How to perform it: Stand facing a sturdy wall or fence. Lean forward so your body is at a strict 45-degree angle, placing your hands flat against the wall at shoulder height. Lift one knee up to your chest, keeping the ankle flexed. On command, violently switch your legs, driving the raised foot back into the ground while punching the other knee up.
Why it works: Acceleration requires pushing backward to go forward. This drill completely removes the need to balance, allowing the athlete to feel the exact 45-degree body angle and piston-like leg action required during the first 10 yards of a sprint.
Coaching tips: Your body must form a perfectly straight line from your ears through your shoulders, hips, and down to your planted ankle. Do not bend at the waist.
Common mistakes: Striking the ground with the heel or letting the ankle collapse. You must maintain stiff, spring-like ankles to transfer force into the ground.
4. Heavy Sled Pushes
How to perform it: Load a prowler sled with heavy weight. Grip the low handles so your torso is nearly parallel to the ground. Push the sled forward for 15 to 20 meters, taking long, deliberate, powerful steps.
Why it works: Sprinting speed is directly correlated to how much force you can push into the ground. This drill isolates the feeling of applying massive horizontal force to overcome resistance, building the specific lower-body power needed to accelerate rapidly.
Coaching tips: Fully extend your back leg on every single push. You want to feel a straight line of power from your shoulder all the way down to your driving foot.
Common mistakes: Taking short, choppy, frantic steps. You must take your time and push completely through the ground on every single stride.
5. Flying 10s
How to perform it: Set up a 20-meter acceleration zone followed immediately by a 10-meter “fly” zone marked by cones. Smoothly build up to 95 percent of your top speed. The moment you hit the fly zone, maintain absolute 100 percent max effort but relax your face and shoulders entirely.
Why it works: This is the ultimate top-speed drill. It teaches the nervous system how to maintain maximum upright velocity without the physical strain of accelerating from a dead stop.
Coaching tips: Fast hands, fast feet. At top speed, you should feel like you are floating over the track, not grinding into it.
Common mistakes: Tensing up and trying to push harder inside the 10-meter zone. Tension is the enemy of speed; you must stay loose to run fast.
Common Mistakes Athletes Make
Linear speed errors are incredibly common in amateur sports, but they are easy to fix once you understand the physics of running.
Over-Striding: This happens when an athlete tries to cover more ground by reaching their lead foot far out in front of their hips. This causes the heel to strike first, acting as an immediate braking force that violently slows the body down.
How to fix it: Drill your A-Skips heavily. You must train yourself to strike the ground directly underneath your center of mass with the ball of your foot.
Side-to-Side Arm Swing: Swinging the arms across the midline of the chest. Because the body naturally balances itself, crossing the arms forces the hips to twist horizontally, wasting immense amounts of energy that should be propelling you forward.
How to fix it: Use the Seated Arm Sprints. Force your hands to travel in a straight, linear path from your face down to your back pocket.
Popping Up Too Early: Standing completely upright on the first or second step of a sprint. This destroys all horizontal momentum, turning your forward drive into an inefficient vertical bounce.
How to fix it: Stare at a spot on the ground three meters in front of you when you start. Keep your chin tucked and let your body angle rise gradually over the first 15 yards.
Running with “Backside Mechanics”: Letting the heels kick way up toward the glutes behind the body after toe-off, delaying the leg from swinging forward for the next step.
How to fix it: Focus exclusively on driving the knees upward in front of you. Once your foot leaves the ground, bring it forward immediately.
How Private Coaching Accelerates Improvement
Linear speed mechanics happen in the blink of an eye. Trying to self-diagnose whether your ground contact time was slightly too long or your acceleration angle was five degrees too high is incredibly difficult without technology and a trained eye.
This is where private coaching is essential. Private coaching provides faster skill development by utilizing expert eyes and slow-motion video analysis. A private speed coach offers personalized feedback tailored to your specific biomechanics, making it easy to catch habits like a side-to-side arm swing immediately. This targeted instruction allows athletes to focus on correcting mistakes early before they become ingrained muscle memory. Ultimately, mastering your speed mechanics in a 1-on-1 environment provides massive confidence building, allowing you to step onto the field knowing you are the fastest player out there.

Frequently Asked Questions about Linear Speed Mechanics
How often should athletes practice linear speed mechanics?
Athletes should practice form drills (like A-Skips and arm swings) daily as part of their warm-up. However, true max-effort speed training (like Flying 10s) should only be done 2 to 3 times a week to allow the central nervous system to recover.
What age should athletes start working on this?
Athletes as young as 7 or 8 can begin learning the basics of arm swing and not running on their heels. The earlier the mechanics of running in a straight line are introduced, the less un-teaching has to happen later.
How long does it take to improve?
With focused, intentional practice, players can see a dramatic improvement in their running form and sprint times in just 4 to 6 weeks. Breaking the habit of severe over-striding may take slightly longer.
Can you actually teach speed, or is it just genetics?
Genetics determine your absolute maximum potential, but almost every single amateur athlete is currently running well below their genetic ceiling due to poor mechanics. You can absolutely teach speed by improving force application and eliminating energy leaks.
Do private coaches help with this?
Absolutely. Private strength and speed coaches are essential for breaking down the biomechanics of the sprint stride, providing video feedback, and isolating specific postural flaws so the athlete can practice effectively.
Conclusion
Linear speed mechanics are the undeniable foundation of an explosive, breakaway athlete in any sport. Without them, you are leaving your athletic potential on the table and playing directly into the opponent’s hands by remaining slow and inefficient. Improvement is highly achievable with proper training, but it requires discipline. Encourage yourself to focus on your arm path and your ground strike before you focus on simply trying harder, and consistent practice will inevitably yield effortless, blinding speed.
