Aside from the positioning of my knees, I also did not extend my arms correctly and widely. In order to improve this, the arm stretches I planned can help me develop a wider range of motion for my arms. In addition to reducing back pain, neck pain, and tendonitis: arm stretches can improve my posture, keeping the muscles in my arms flexible, strong, and stable. Without it, muscles may shorten and become tight over time, preventing me from moving deeply and with ease.
