Abstract
An abdominal exercise device is described that includes an alarm means to promote proper user positioning for abdominal muscle isolation. The exercise device includes a frame; a seat carried on the frame; a backrest attached to the frame, the backrest including a mounting plate and a backrest pad pivotally attached to the mounting plate; a user perceivable alarm; a first sensor associated with the backrest to sense the pressure exerted by the user on the backrest, the first sensor activating the alarm when the pressure is outside a preset range; and, optionally, a second sensor associated with the backrest to sense the angle of the backrest pad, the second sensor activating the alarm when the angle is outside a preset range.
