Children can start supervised strength training once they are mature enough to follow instructions and practise good technique, which for many is around age seven or eight. Readiness matters more than a birthday, and the focus is on movement quality, not lifting heavy.
The old belief that strength training stunts growth is not supported by the evidence. Properly supervised programs are considered safe for children and teens, and Canada’s 24-Hour Movement Guidelines recommend muscle and bone strengthening activities at least three days a week for ages 5 to 17.
What it looks like at different stages
- Younger children: body-weight movements, climbing, jumping, throwing, light medicine balls and bands, taught as games and skills
- Pre-teens: learning squat, hinge, push, pull and carry patterns with light loads and plenty of repetition
- Teens: gradually heavier, structured training once technique is consistent, alongside speed and jump work
What makes it safe
- Qualified supervision at all times
- Technique before load, with small increases
- A proper warm-up
- Rest days, and enough sleep and food
- No maximal lifts or training to exhaustion for younger athletes
- Stopping if something hurts
Benefits beyond strength
- Better movement skills and coordination
- Stronger bones
- More confidence in sport and physical activity
- A foundation that helps young athletes handle the demands of their sport
When to check with a doctor first
Speak with your child’s doctor before starting if they have a heart condition, uncontrolled high blood pressure, a seizure disorder, or a current injury. Ongoing pain around a joint in a growing child should be assessed, not trained through.
