Much appreciated for the video guide! Gotta admit though I’m confused as to the purpose of the U ring that connects the leg lift to the main frame. Is that just so it doesn’t move around a lot in transit?
The U-shaped bolt is used to secure the Hook leg frame when performing sit-ups. If you have any other questions in the future, please feel free to contact us. Thanks. --HARISON Team
