AYC Movement Library: Single Leg Balance

(The foundation of stability, control and athletic movement)

Single Leg Balance: Where Athletic Control Begins

Before an athlete can sprint…

Before they can jump…

Before they can change direction…

They must first learn to control one leg.

Every stride in running.

Every take-off.

Every landing.

Every cut.

Happens on one leg.

Balance isn’t simply standing still.

It’s the ability to control your body while moving.

At AYC, we don’t train balance for balance’s sake.

We train balance because it underpins athletic performance.

1. What is the movement?

Single leg balance is the ability to maintain control while standing on one leg.

It requires the body to organise itself through:

• The foot

• The ankle

• The knee

• The hip

• The trunk

At the same time.

Examples include:

• Static Single Leg Balance

• Single Leg Reach

• Single Leg RDL

• Balance with Ball Toss

• Dynamic Balance Holds

Although it looks simple…

it’s one of the most demanding movement skills in athletic development.

2. Why it matters

Single leg balance develops:

✔ Foot stability

✔ Ankle control

✔ Hip stability

✔ Postural control

✔ Proprioception

✔ Body awareness

✔ Movement confidence

These qualities underpin almost every athletic movement, including:

• Running

• Sprinting

• Jumping

• Landing

• Deceleration

• Change of direction

Why?

Because sport happens one leg at a time.

Every stride is a controlled single-leg balance.

Every landing starts with stability.

At AYC we often say:

“You can’t produce force if you can’t first control it.”

Balance builds control.

3. When to use it (Age / Stage)

Stage 1: Athletic FUNdamentals (6–8)

A major priority.

Develop:

• Confidence

• Coordination

• Posture

• Stability

Children should become comfortable balancing in multiple positions.

Stage 2: Athletic Development (9–11)

Increase challenge through:

• Movement

• Reaching

• Rotation

• Catching

• External perturbations

Control should remain excellent.

Stage 3: Athletic Performance (12–16)

Progress to:

• Reactive balance

• Sport-specific positions

• Landing control

• Dynamic stability under fatigue

Balance becomes athletic.

4. How to assess it

At AYC, we don’t assess how long an athlete can simply stand still.

We assess how well they maintain control.

Can they:

• Keep the foot stable?

• Control the knee?

• Keep the pelvis level?

• Maintain posture?

• Stay balanced while moving?

Watch for:

• Foot collapse

• Knee position

• Hip stability

• Trunk control

Simple assessments include:

• Single Leg Hold

• Single Leg Reach

• Star Balance Patterns

Quality always comes before duration.

5. What good looks like

Good balance looks quiet.

The foot stays active.

The knee tracks well.

The pelvis stays level.

The trunk remains tall.

Good balance should show:

✔ Stable foot

✔ Controlled knee

✔ Level hips

✔ Strong posture

✔ Relaxed breathing

✔ Minimal wobble

Balanced.

Controlled.

Efficient.

Not rigid.

6. Coaching cues

At AYC we use simple cues:

“Grip the floor.”

“Stay tall.”

“Level hips.”

“Soft knee.”

“Control the wobble.”

Simple.

Repeatable.

Effective.

7. Common errors

Foot collapse

Arch drops inward.

Problem:

Reduced stability.

Knee falls inwards

Loss of alignment.

Problem:

Poor hip control.

Excessive trunk movement

Upper body sways.

Problem:

Reduced postural control.

Locked knee

Rigid posture.

Problem:

Poor movement quality.

Looking down constantly

Loss of posture.

Problem:

Reduced body awareness.

8. Fixes, regressions & progressions

Regressions

• Supported Single Leg Hold

• Toe Touch Balance

• Split Stance Hold

• Tandem Balance

Build confidence first.

Fixes

Foot collapsing?

→ Barefoot balance work.

Knee falling in?

→ Strengthen hip control.

Poor posture?

→ Reduce task difficulty.

Too much wobble?

→ Shorter holds with better quality.

Progressions

• Eyes Closed Balance

• Ball Toss Balance

• Single Leg Reach

• Single Leg RDL

• Reactive Balance

• Hop to Balance

Always progress in the same order:

Control → Stability → Movement

9. Research & Development Relevance

Research consistently shows that single-leg stability plays a key role in movement efficiency, injury resilience and athletic performance.

Developing balance improves neuromuscular control, proprioception and lower-limb stability—qualities that support running, sprinting, jumping and changing direction.

Athletes who can control one leg effectively are better prepared to produce and absorb force safely.

This is why single leg balance remains a core movement within the AYC Movement Library.

Not because it’s easy.

Because it’s essential.

The AYC Takeaway

Balance isn’t about standing still.

It’s about staying in control while moving.

Every stride.

Every jump.

Every landing.

Starts on one leg.

At AYC, balance isn’t an isolated skill.

It’s the foundation for every movement that follows.

Build the mover first.

Build the athlete second.

Build performance third.
