The first step in acceleration can make or break an athlete’s speed.
Most young athletes try to reach forward when they start. It feels fast. It looks aggressive. But mechanically, it actually slows them down.
In this live coaching session from F.A.S.T. School, Coach Duane Carlisle breaks down what really creates an explosive first step, and why proper loading and projection are the keys.
The Real Foundation of an Explosive First Step
Acceleration doesn’t start with the foot. It starts with posture.
1. Posture and Position
Before an athlete ever moves, their body position determines how much force they can produce.
Proper setup includes:
- Shoulders stacked over hips
- No space between chest and thigh in the start position
- A forward projection angle
If posture is off, power leaks immediately.
Speed begins with alignment.
2. Load to Explode
One of the biggest mechanical errors in acceleration is starting with a vertical shin.
When the shin is vertical, the athlete isn’t loading the front leg effectively. Without load, there’s no stored elastic energy.
But when the knee moves out over the toe and the weight shifts onto the ball of the foot, the muscle stretches like an elastic band.
Move two joints away from each other — the muscle loads. Load it correctly — it snaps.
This is the principle of “load to explode.”
The more effectively an athlete loads, the more force they can produce when they strike.
3. Push, Don’t Reach
Most athletes perform what’s called a “reach step.”
Here’s what that looks like:
- Foot stays low to the ground
- Athlete reaches forward instead of pushing
- Hips act like an emergency brake
- Ground contact time increases
It feels aggressive, but it’s inefficient.
Instead, acceleration requires:
- Punching the knee
- Striking down and back
- Attacking the ground violently
You don’t strike to the ground. You strike through the ground.
When an athlete projects their center of mass forward and strikes back through the ground, they move forward explosively.
Acceleration is not passive. It’s forceful and intentional.
Why This Matters for Sports Parents
Understanding this difference helps you reinforce the right cues instead of encouraging habits that slow your athlete down.
The gap between average speed and explosive speed often comes down to first-step mechanics.
When posture is correct, load is established, and the athlete pushes instead of reaches, acceleration changes immediately.
Ready to Build Real Acceleration?
If you want your athlete trained in this system (not just hearing about it, but coached through it step by step!) there are two ways to get started.
F.A.S.T. School provides in-person acceleration and speed training built on these exact mechanics. Athletes learn how to set their posture, properly load, and project with intent so their first step becomes explosive instead of inefficient.
If you’re not local, Speed Academy delivers the same principles through remote training. Your athlete can follow structured programming and receive coaching guidance designed to build real acceleration, not just temporary quickness.
Speed isn’t something athletes are simply born with. It’s a skill. And when it’s taught correctly, it improves.
