Locking Knees

Locking out your knees during exercises like squats isn't inherently bad if done correctly. According to Sal Di Stefano, the issue arises when people lock their knees and relax their muscles, allowing the joints to support the weight. This can cause problems since it places undue stress on the joints. However, if you lock out your knees while keeping your muscles engaged and supporting the movement, it's generally safe and effective. Maintaining muscle tension throughout the movement helps prevent injury and ensures that your form remains stable and controlled 1 2 3.

In summary:

• Locking out knees is safe if muscles remain engaged.
• Avoid relaxing muscles and letting joints support the weight.
• Focus on maintaining proper form and muscle tension throughout the movement.
