What common errors in performing zenkutsu dachi are likely to produce leg injury?

Several common errors in performing Zenkutsu Dachi (Front Stance) can increase the risk of leg injury. First, failing to align the front knee directly over the ankle is a critical mistake. If the knee extends beyond the toes, it places excessive stress on the knee joint, increasing the risk of patellofemoral pain syndrome (runner's knee) or meniscus injury. Conversely, if the knee is too far behind the ankle, it reduces stability and can strain the quadriceps muscles. Second, not keeping the rear leg straight and the rear heel firmly planted on the ground can strain the calf muscles and Achilles tendon. A bent rear leg also compromises the structural integrity of the stance, reducing power and balance. Third, failing to maintain proper spinal alignment, such as leaning forward or arching the back excessively, can lead to lower back pain and instability, which can indirectly affect leg stability. An improperly aligned spine disrupts the body's center of gravity, forcing the legs to compensate and increasing the risk of strain. Fourth, insufficient hip engagement prevents the full power from being generated during movement transitions and impact. Lastly, tensing muscles unnecessarily in the legs can also lead to muscle injury.
