Specialization vs. varied training: what helps young athletes most?

Does strength training stunt growth in kids and teenagers?

Can strength training stunt growth in kids and teens? A lot of parents and coaches have heard that claim — but what does the evidence actually say? In this episode, we look beyond the myth and explore how young athletes canbuild strength in a safe, healthy, and effective way. That includes more than just lifting weights. We are talking about bodyweight training, resistance work, movement control, technique, injury prevention, explosiveness, and gradual progression. And how all of this fits into long-term athletic development for children and teenagers. This podcast is made for parents and coaches who want to understand what actually helps young athletes develop. I created this podcast because I’m a parent and a coach of young athletes myself. And I wanted to make relevant knowledge easier for other parents and coaches, to understand and apply in real life. This episode was produced with the help of AI and manually reviewed and edited before publication by me. The content is intended as a general and accessible overview of research, professional knowledge, and practical experience related to training young athletes.
