发明名称 Abdominal exercise machine
摘要 The abdominal exerciser of the present invention is an exercise device designed to work the abdominal and oblique muscle groups. The abdominal exerciser includes a sled that is supported by and slides or rolls along at least one track. The upper body support is ergonomically positioned higher than the sled, and fixed to a cross bar supported by the track. The cross bar is designed to rotate forward to simulate an abdominal exercise "crunch" motion when the knees are brought within proximity of the upper body support.
