Elite Agility Coaching

Next Sunday FREE WR TRAINING. 11 am at Dover Boys and Girls Club. All ages.

Weights can help with speed — but they’re usually not the main driver of speed. Here’s why.

---

1️⃣ Speed is mostly neurological, not muscular

Speed is primarily about how fast your nervous system can:

Recruit muscle fibers

Fire them in the right sequence

Coordinate movement efficiently

Sprinting fast is a skill, not just a strength test.

For example, athletes like Usain Bolt didn’t become the fastest in the world just by lifting heavy — they trained sprint mechanics, acceleration, and maximal velocity repeatedly.

---

2️⃣ Force vs. Speed (They’re Related, But Not the Same)

In physics:

> Power = Force × Velocity

Lifting heavy weights increases force production.
But sprinting requires applying force very quickly (high rate of force development).

Heavy squats:

Build maximum force

But are usually slow

Sprinting:

Requires fast force in milliseconds

If you get stronger but can’t apply force quickly, your speed won’t improve much.

---

3️⃣ Specificity Principle

Your body adapts specifically to what you train.

Heavy squats → You get better at heavy squats

Sprinting → You get better at sprinting

That’s why top speed training focuses on:

Short sprints (10–60m)

Plyometrics

Resisted sprints

Technical drills

Weights are usually support work, not the main event.

---

4️⃣ Too Much Weight Training Can Even Slow You Down

If poorly programmed, weights can:

Increase muscle mass without improving power

Create stiffness

Reduce mobility

Cause fatigue that interferes with sprint sessions

Many track athletes lift — but carefully, and in small doses.

---

5️⃣ When Weights Do Help Speed

Weights are helpful when:

You’re weak relative to your bodyweight

You need more force for acceleration

You train explosively (e.g., jump squats, Olympic lifts)

Elite programs combine:

Sprint work

Plyometrics

Strength training

Even teams in the National Football League use weights mainly to support power, not replace speed training.

Simple Summary

Speed is about:

🧠 Nervous system efficiency

⚡ Fast force production

🏃 Technique and mechanics

Weights build strength.
Sprinting builds speed.
The best results come from combining them correctly.
