Here's why:
* Jeet Kune Do's focus on adaptability: Horse stance is a powerful stance for generating force and stability, but it's a relatively static position. Lee believed in fluidity and adapting to the opponent's movements, making horse stance less ideal for his style.
* Lee's emphasis on speed and explosiveness: Horse stance, while strong, can be slow to transition from. Lee prioritized speed and agility, favoring stances that allowed him to move quickly and strike effectively.
* Lee's unique fighting style: Jeet Kune Do incorporated elements from various martial arts, including boxing, Wing Chun, and fencing. His style was a blend of techniques that didn't necessarily rely on a single stance.
However, it's important to understand that Bruce Lee likely did practice horse stance as part of his training. It's a fundamental stance in many martial arts, and he likely used it to develop strength, balance, and stability. He just didn't rely on it exclusively in his fighting style.
Ultimately, while Bruce Lee didn't solely rely on the horse stance, he likely integrated it into his training and utilized its principles to develop his own unique and dynamic fighting style.
