Why Shin Angle Matters in Acceleration

When it comes to acceleration, your shin angle tells the truth.

In the side-by-side examples I’m sharing, you’ll see two athletes taking their first step out of a start. One athlete shows a low, aggressive shin angle pointed diagonally toward the ground. The other athlete’s shin is much more vertical, pointing closer to upright.

Let’s break down why that matters.

1. Low Shin Angle = Forward Projection

In acceleration, you want your body to project you forward, not upward.
In the first example, the athlete’s shin is low and angled forward. That position does three things:

• Directs force horizontally, which is exactly what acceleration requires

• Keeps the center of mass over the foot, loading the body for the next step

• Creates a strong and stable push-off position, like loading a spring

A forward shin means forward speed.

2. High Shin Angle = Vertical Push

In the second example, the shin is much more upright. When the shin rises too early:

• Force leaks upward instead of forward

• The first steps become choppy and slow

• The athlete spends too long on the ground, “pushing tall” instead of projecting out

This leads to the classic problem: they stand up too fast, which kills the acceleration phase.

3. The First 3 Steps Are Everything

Most athletes don’t struggle with top speed—they struggle with the first 10 yards.

A low shin angle at the start sets up:

• Longer, more powerful pushes

• Better forward momentum

• A smoother rise to upright sprinting mechanics

If the shin angle is wrong early… the whole acceleration phase suffers.

4. How to Train It

You can improve shin angles with:

• Wall acceleration drills (teaches correct angles safely)

• Pushup Start

The key is teaching the athlete what “forward projection” feels like.

Bottom Line

Your shin angle is your steering wheel.

Get it right, and you accelerate like a rocket.

Get it wrong, and you’re fighting against your own mechanics.
