Master Lead Leg Mechanics for Better Pitching!

Weāve all heard it: āAll players are different.ā Itās a mantra we all seem to agree onāuntil we donāt. After just a few minutes of conversation, many coaches, trainers, and experts revert to discussing biomechanical principles and so-called absolutes. In practice, we end up ignoring individuality, defaulting to a ācopy-pasteā model of the so-called āideal movementā or mechanics.
But what is this ideal? Itās often nothing more than a culturally ingrained concept of movement that dismisses natural variation.
This weekend, I came across a video from a renowned pitching institute. They work with amateur and professional players, especially during this time of year.
The video focused on lead leg movement patterns, particularly avoiding energy leaks in the lead leg.
Hereās a summary of their explanation:
- Inefficient lead leg movementsāsuch as excessive knee flexion, bowing out of the knee or foot, or failure to achieve a clawback mechanismāare often seen as pattern or timing issues.
- Athletes may do countless reps and drills to fix these issues, yet sometimes their bodies simply wonāt adapt.
My Take: NO, OF COURSE NOT!!!
Isnāt it strange that they admit:
āAthletes try everything, yet their bodies just wonāt get into these positions.ā
Of course, their bodies resistāitās against their natural way of moving!
These positions donāt align with their individual natural motor preferences. Itās not how their bodies are wired.
This isnāt just about motor dominanceāitās about the fundamental differences in how the body functions and how it activates the Anterior or Posterior muscle chains during movement.
How does the lower half of an Anterior Muscle Chain Dominant (WB) Athlete work:
- When bending the knee:
- External Rotation Upper Leg
- Internal Rotation Lower Leg
- Foot Outward
- When straightening the knee:
- Internal Rotation Upper Leg
- External Rotation Lower Leg
- Foot Neutral
How does the lower half of a Posterior Muscle Chain Dominant (WT) Athlete work:

- When bending the knee:
- Internal Rotation Upper Leg
- External Rotation Lower Leg
- Foot Inward
- When straightening the knee:
- External Rotation Upper Leg
- Internal Rotation Lower Leg
- Foot Neutral

As you see in the pictures, these differences are clearly visible in movements like sprinting!
These visible variations highlight how each athleteās natural motor preferences influence their movement patterns.
The Real Issue:
Weāre still stuck in a one-size-fits-all culture, forcing athletes into āidealā mechanics that often conflict with their natural motor preferences. Instead of embracing individuality, we create unnecessary barriers to performance or even injuries.
Letās commit to doing better. Letās respect the unique ways athletes move and stop trying to mould everyone into the same outdated āideal.ā Individuality isnāt just a mantraāitās the foundation of elite performance.
