Training The Developing Athlete -Wisdom Wednesday #2

The term developing athlete is a loaded one. In this post, I’ll break down what it means to me and how I approach coaching both sport-specific skill acquisition and strength and conditioning throughout their development.

Defining the Developing Athlete

To me, a developing athlete is anyone who hasn’t completed puberty. Puberty typically spans ages 10–17 in females and 11–17 in males, though individual timelines vary. As coaches, it’s essential to assess the athlete in front of us rather than rely solely on age.

Key Considerations in Coaching Developing Athletes

1. Understand the Individual

No two athletes are the same. Movement patterns, injury history, training age, and maturity levels vary widely. Individualized programs—not cookie-cutter templates—are key to safe and effective development.

2. Chronological Age ≠ Training Age

Two 16-year-olds may be worlds apart.

• Athlete A has trained consistently for years and is ready for advanced programming.

• Athlete B has minimal training experience and needs a foundational approach.

  
  

Heavy lifting is earned—not given.

3. Master the Basics First

Before loading movements, teach and reinforce proper patterns:

• Bilateral/Unilateral Squat & Hinge

• Horizontal & Vertical Push/Pull

• Breathing & Bracing Mechanics

  
  

Lay the foundation before pushing intensity.

4. Play Multiple Sports

Early specialization is a major pitfall. Athletes benefit greatly from playing multiple sports, especially through high school. Benefits include:

• Moving in different planes

• Developing general athleticism

• Preventing burnout

  
  

Some of the best baseball players I’ve coached also played basketball—no coincidence.

5. Delay Specialization

Despite common belief, early specialization doesn't improve long-term success. In fact, research shows it often leads to shorter careers and higher burnout rates. Let young athletes explore, have fun, and fall in love with the game first.

6. Exploration Over Prescription

This is at the heart of my coaching philosophy — especially when it comes to skill development like hitting, throwing, and fielding.

In early sessions, I don’t rush to correct. I watch. I ask questions. I want to learn how the athlete moves and why they’re moving that way — then I coach.

Often, athletes move a certain way simply because someone told them to. Common cues like:

• “Stay back”

• “Get to a balance point”

• “Drive the ball the other way”

  
  

…might work for some, but not for everyone. Instead of forcing athletes into rigid molds, I encourage exploration. Let them try, feel, and discover what works for their body.

When athletes explore movement, they gain awareness. When they gain awareness, they improve.

7. Keep It Fun

Training can be repetitive. Break it up! Play Nerf basketball, spike ball, or have competition days. Create a positive association with the weight room.

And remember: sport is meant to be fun. If you haven’t watched The Sandlot in a while, do it—it’s a great reminder of why we play.

Take care and see you next Wednesday.
