Why Strength Is the Most Important Physical Skill Your Child Can Develop

Written by Paediatric Exercise Physiologist, Ben Hall – Ocean Kids Health

When most parents think about helping their child become more active, they often picture running faster, kicking a football further, or learning a new sport.
But underneath almost every physical skill is one thing that doesn’t always get the attention it deserves… strength!
Strength isn’t just about lifting heavy weights or building big muscles. For children, strength is the foundation that helps them move confidently, participate in sport, keep up with their friends and develop the physical resilience they need as they grow.

Strength is the foundation for movement

Imagine trying to build a race car with a small engine. No matter how good the tyres or suspension are, it won’t perform at its best. Strength is the engine behind movement – it helps children move more efficiently, confidently and powerfully.

Children rely on strength every day to:

  • Run and change direction.
  • Jump, hop and skip.
  • Climb playground equipment.
  • Carry their school bag.
  • Ride a bike or scooter.
  • Throw, catch and kick a ball.
  • Maintain good posture during the school day.

When a child doesn’t have enough strength for these everyday activities, they often compensate by using different movement patterns, become tired more quickly, or simply avoid activities that feel difficult.

Over time, this can affect both their confidence and their willingness to be active.

Strength helps with every sport

Whether your child plays (or is wanting to play) sports such as football, netball, basketball, swimming, gymnastics or athletics, strength underpins performance.

Children with good strength are generally better able to:

  • Produce more power when they run and jump.
  • Maintain good technique as they become tired.
  • Improve balance and coordination.
  • Develop new skills more easily.
  • Reduce their risk of injuries.

Importantly, strength training for children doesn’t look like an adult gym workout. It focuses on learning quality movement, developing body control and gradually building strength in a safe, age-appropriate way.

Strength helps children outside of sport too

One of the biggest misconceptions is that strength only matters for sporty children.
In reality, every child benefits from becoming stronger.

We’ve worked with children who struggle to:

  • Get up from the floor.
  • Keep up during PE.
  • Climb playground equipment.
  • Walk longer distances without fatigue.
  • Carry their school bag.
  • Sit with good posture in the classroom.

As their strength improves, these everyday activities often become easier, helping them participate more confidently both at school and at home.

Confidence often grows alongside strength

One of the best parts of our job is seeing what happens beyond the physical improvements.
Children who become stronger often become more willing to have a go. They’ll volunteer to join in at sport, attempt the monkey bars, ride their bike further, or simply feel more confident playing with their friends. Success builds confidence, and confidence encourages children to keep being active. It’s a positive cycle that can have long-lasting benefits.

Can children safely do strength training?

Absolutely.
Current research consistently shows that appropriately supervised strength training is both safe and beneficial for children and adolescents.

The key is that programs should be designed specifically for children, with an emphasis on:

  • Learning good movement patterns.
  • Using appropriate resistance.
  • Gradually increasing the challenge.
  • Keeping sessions fun and engaging.
  • Being supervised by qualified professionals, such as an Exercise Physiologist

Strength training for children is very different to bodybuilding or powerlifting. The goal isn’t to lift the heaviest weight possible – it’s to build healthy, capable bodies that are ready for sport and everyday life.

How Exercise Physiologists can help

Every child develops differently, and there’s no single program that suits everyone.
An Accredited Exercise Physiologist can assess your child’s strength, movement skills and physical development before creating an individualised program based on their goals.

Whether your child wants to improve sporting performance, struggles with coordination, has low muscle tone, is recovering from injury or simply needs more confidence with movement, a tailored program can make a significant difference.

If you’re wondering whether your child could benefit from building strength, we’d love to help. Our Exercise Physiology team can assess your child’s movement and recommend the most appropriate pathway, whether that’s individual Exercise Physiology sessions or completing one of our SportStrong programs.
