Training Splits for Youth Athletes

Why Upper/Lower Splits Aren’t the Best for Young Athletes – And What Works Better

For years, the fitness industry has pushed the idea of body part splits – chest day, leg day, upper body, lower body – as the gold standard for building strength. But when it comes to youth athlete development, these training methods fall short. Young athletes need more than just muscle; they need speed, coordination, agility, balance and injury resilience. So, what’s the best approach? Let’s break it down.

The Problem with 'Sport-Specific'

Traditional upper/lower body training and sport-specific training focus on isolating muscle groups, often leading to overtraining certain areas while neglecting full-body athletic development. This method doesn’t align with the dynamic movements required in sports, where athletes use their entire body in coordination – not just their legs or arms in isolation.

Some key issues with upper/lower splits for youth training include:

  • Lack of Movement Integration: Sports require full-body control, not isolated muscle strength.

  • Higher Risk of Imbalances: Training certain areas more than others can lead to injury.

  • Limited Transfer to Sport: Real-world sports performance demands coordination, not just strength.

  • Doesn’t Support Growth & Development: As young athletes grow, their bones lengthen before muscles and tendons fully adjust, increasing injury risk. Training should focus on building balanced, full-body strength to support this process.

  • Can Feel Too Serious Too Soon: Younger athletes thrive when training is fun and engaging, rather than overly structured or rigid.

The Alternative? Full-Body Strength Training for Youth Athletes

Instead of breaking training into muscle groups, youth athletes should focus on full-body movements that develop strength while keeping up with their growing bodies. A balanced approach ensures that all muscle groups develop together, reducing the risk of injury and improving overall athleticism.

Key exercises include:

  • Squats, Lunges and Step-Ups – Building lower-body strength and stability

  • Push-ups, Pull-ups and Crawls – Developing upper-body control and coordination

  • Jumping, Hopping and Landing Mechanics – Improving explosiveness and joint stability

  • Core Work and Rotation Exercises – Enhancing balance, coordination and power transfer

Making Training Fun & Engaging

There must be some seriousness to training. However, for young athletes, training shouldn't feel like a chore. Incorporating games, reaction-based drills and team challenges makes strength development more enjoyable while reinforcing key movement patterns. Keeping sessions varied and interactive helps maintain motivation and long-term progress.

Final Thoughts

Young athletes don’t need bodybuilding-style training; they need movement-based, full-body development that supports their sport and growing bodies. By focusing on foundational movements, keeping training fun and emphasising balanced strength, we can help them stay strong, injury-free and ready for the demands of their sport.
