If you experience fishtailing in archery, physical limitations may be causing it. For example, having weak shoulder muscles or poor posture can affect your ability to maintain a steady aim and release the arrow smoothly. Similarly, if you have an injury or condition that affects your grip strength or hand-eye coordination, this can also contribute to fishtailing. Working with a coach or trainer is important to help you identify any physical limitations and develop exercises and techniques to address them. Additionally, proper warm-up and stretching before shooting can help you improve flexibility and reduce the risk of injury that might exacerbate fishtailing.
