Strength and Endurance in Children

If your child seems to tire quickly, struggles to keep up with other kids, or avoids physical activity, you’re not alone. Strength and endurance challenges can make everyday movement more difficult.

These challenges can affect posture, play, and participation in activities at home, school, and sports. Our physical therapists help children build strength, improve endurance, and feel more confident in their bodies.

What are strength and endurance challenges?

Strength and endurance challenges happen when a child has difficulty maintaining muscle effort over time. This can make it harder to participate in physical activity, keep up with peers, or complete everyday tasks without fatigue.

Signs your child may have strength or endurance challenges

  • Tires quickly during play or activity

  • Difficulty keeping up with other children

  • Poor posture or slouching

  • Avoids physical activity

  • Struggles with stairs, climbing, or playground equipment

  • Needs frequent breaks during movement

How physical therapy helps

Physical therapy helps children build strength and improve endurance for everyday movement.

This can include:
• Strength-building exercises
• Endurance and activity tolerance training
• Postural support and alignment work
• Functional movement practice (stairs, climbing, play)
• Building confidence in physical activity

What should I do next?

If you’re unsure whether your child’s strength or endurance is on track, a simple screening can help give you clarity. Early support can help your child feel stronger and more confident in everyday activities.

We help families from Rexburg, to Rigby to Ashton, Island Park, and West Yellowstone understand what’s going on and what to do next.
