One question we’ve been asked a lot recently by patients and their families: Is strength training safe for teenagers?
There’s still a common myth that strength training isn’t safe for adolescents — but it can be both safe and beneficial with the right considerations.
Supervised strength training during adolescence can help improve strength, coordination, injury resilience and overall athletic performance, while also building great lifelong exercise habits.
Is it safe?
Yes. When exercises are age-appropriate, well supervised, and focus on good technique first. Teenagers don’t need to lift maximal weights. Learning movement skills and gradually building strength is the priority.
How often should teens strength train?
For most adolescents, 2–3 strength sessions per week is a great place to start. This allows enough stimulus for improvement while still leaving time for other sports and activities.
Think about total weekly load
Many teens are already doing a lot of sport, training and school activities. Strength training should be considered part of their total weekly training load, along with any other exercise. Balancing sport, gym sessions and rest is key.
Recovery matters
Growing bodies need time to recover. Ensuring adequate rest days, good sleep and sensible progression helps reduce the risk of overload injuries.
Done well, strength training can be a powerful tool to help teenagers stay active, strong and resilient as they grow.
If you’re unsure how to safely introduce strength training for your teenager, a physiotherapist can help guide exercise selection, technique and training load
