I appreciate the engaging 20-minute standing ab workout video on KZbin. The emphasis on standing exercises targeting the abdominal muscles is a great approach for those who prefer variety and find floor exercises challenging. The diverse exercises in the video make it a well-rounded workout, providing an effective and efficient way to strengthen the core muscles. Grateful for the clear instructions and the accessibility of the routine, making it easy for users to follow along at home. Overall, a positive and beneficial addition to my fitness routine.
