Dropping your 40-yard dash time comes down to three things: better start mechanics, stronger acceleration through the first 20 yards, and the right training off the field. Most athletes leave time on the table not because they lack raw speed, but because their technique breaks down in the first few steps or they never train the specific force production that sprinting demands. Here’s how to address each piece.
Know What Each Phase Demands
The 40-yard dash isn’t one continuous sprint. It breaks into three measurable segments, and each one tests a different ability. Your 10-yard split reflects pure lower-body explosiveness and how quickly you can accelerate from a dead stop. Your 20-yard split reveals how long you can sustain that acceleration before transitioning into top-end speed mechanics. The final 20 yards measure your ability to maintain speed once you’ve reached it.
This matters because the movement patterns differ between phases. The first 10 to 15 yards require a piston-like leg action, driving straight back into the ground. Once you transition toward top speed, your legs shift into a cyclical motion with higher knee recovery and more time in the air. Training one pattern won’t automatically improve the other.
Fix Your Three-Point Stance
Your time starts the moment you move, so a sloppy setup costs you before your first step. In the set position, your hips should sit above your shoulders, and your shoulders should be ahead of the start line. This forward lean loads your front leg and positions your body to push horizontally rather than pop up vertically.
Place your front foot about two foot-lengths behind the line, with your back foot staggered roughly one foot-length behind that. Your down hand (opposite your front foot) sits just behind the line with your fingers bridged on the ground. Keep most of your weight on your front foot and your down hand, so when you fire out, you’re already falling forward. A common mistake is setting the hips too low, which forces you to rise before you can drive forward, wasting your first fraction of a second.
Win the First 10 Yards
The acceleration phase is where the biggest time improvements live for most athletes. Your goal here is to push the ground behind you at a steep forward angle. Lean your torso roughly 40 to 50 degrees from vertical during the first several steps. This aggressive lean increases your shin angle, keeps the back of your foot off the ground, and channels your force horizontally rather than bouncing you upward.
Each step should fully extend your hip, knee, and ankle simultaneously. This “triple extension” is where your power comes from. Think about driving the ground away behind you rather than reaching forward with your lead leg. Overstriding, placing your foot out in front of your center of mass, acts like a brake on every step. Your foot should contact the ground under or slightly behind your hips during these early yards.
Rise gradually. One of the most common errors is standing upright by step three or four. Your torso should stay low and lift by only a few degrees with each stride, reaching a near-upright posture somewhere around the 15 to 20 yard mark.
Use Your Arms Correctly
Your arms don’t directly push you forward, but they coordinate your leg drive and prevent your torso from rotating. Keep your elbows bent at roughly 90 degrees and pump them straight forward and back. Your hands should travel from about hip height to cheek height without crossing the midline of your body. When arms swing across your chest, your shoulders rotate, your hips follow, and you leak energy sideways instead of channeling it down the field.
Off the line, the arm action is more violent and compact. Drive your lead elbow back hard as your opposite leg pushes off. As you transition to top speed, the arm swing becomes slightly more relaxed but stays on the same forward-back track.
Train Horizontal Force Production
Sprinting from a standstill demands force directed forward, not upward. Your gym work should reflect that. Research comparing the force profiles of different plyometric exercises found that bounding (exaggerated running leaps for distance) produces a horizontal-to-vertical force ratio closest to what happens during an actual sprint start. Standing long jumps rank second. Vertically oriented exercises like countermovement jumps produced the least sprint-specific force ratio, roughly a third of what bounding generates.
Build your plyometric work around these exercises:
- Bounding: Alternate-leg leaps covering as much ground as possible per stride. Focus on driving off the ball of each foot and extending fully through the hip.
- Standing long jumps: Swing your arms and explode forward, sticking the landing. Three to five sets of three to five reps with full recovery between sets.
- Single-leg hops for distance: Same idea as bounding but on one leg, which builds unilateral power and exposes imbalances.
- Sled pushes or resisted sprints: A weighted sled forces you to maintain the forward lean and horizontal push pattern of early acceleration under load.
Plyometric exercises with a strong horizontal component have been shown to be more effective at developing sprint speed than traditional resistance training alone. That doesn’t mean you should skip the weight room, but it means your power training should prioritize pushing forward, not just jumping high.
Build a Strength Base That Transfers
Raw strength gives you more force to put into the ground. Squats, trap bar deadlifts, and hip thrusts build the glutes, hamstrings, and quads that drive every step of the 40. Single-leg work like Bulgarian split squats and step-ups are especially useful because sprinting is a single-leg activity. You’re never pushing off both feet at the same time after the start.
Prioritize heavy, low-rep strength work (three to five reps) during the off-season to build your force ceiling, then shift toward lighter, faster movements as you get closer to testing. Power cleans and jump squats at moderate loads bridge the gap between max strength and the explosive speed you need on the field.
Manage Sprint Training Volume
Max-effort sprinting is taxing. A study measuring fatigue and recovery after repeated 30-meter sprints found that full neuromuscular recovery took up to 72 hours. That means two to three dedicated sprint sessions per week is the practical ceiling for most athletes, with at least 48 hours between sessions.
Within each session, quality matters far more than quantity. Sprint work for the 40 should include distances of 10, 20, 30, and 40 yards, with full rest between reps. Three to five minutes between sprints allows your body to replenish the energy system that powers max-effort bursts. If you’re still breathing hard when you step to the line, you’re training endurance, not speed.
A typical sprint day might look like four to six reps of 10-yard starts from a three-point stance, followed by two to three full 40-yard runs, all at 95 to 100 percent effort. Film yourself or have a coach watch. Technique degrades when you’re fatigued, and practicing bad mechanics just makes them more automatic.
Where You Run Matters
If you have the option, practice on the same surface you’ll be tested on. Sprint spikes on a rubber track produce faster times than cleats on turf because spikes are lighter and the firm surface returns energy instead of absorbing it. Cleats on turf sink slightly with each step, costing you force. If your test will be on turf, train on turf and save the spikes for track work. If the testing surface is a track or hard floor, get comfortable in a pair of lightweight sprint spikes well before test day.
Competitive Benchmarks by Position
Knowing where the bar sits helps you set a realistic target. At the 2026 NFL Combine, the average 40-yard dash time by position group was 4.52 seconds for wide receivers, 4.59 for running backs, 4.71 for linebackers, and 5.26 for offensive linemen. These averages represent the top college athletes in the country, so matching them puts you in elite company. For high school athletes, knocking two to three tenths of a second off your current time over a training cycle is an aggressive but achievable goal with consistent technique and strength work.
