How can I improve my technique for executing a smooth and controlled guitar bend?

To improve your technique for executing a smooth and controlled guitar bend, focus on using your fingertips to push the string up or down gradually while maintaining even pressure. Practice bending to the desired pitch accurately and consistently, and pay attention to your hand positioning and wrist movement for better control. Additionally, work on developing strength in your fingers and wrist through regular practice and exercises specifically designed for bending techniques.
