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.
Claims19
An abdominal exercise device with alarm means to promote proper user positioning for abdominal muscle isolation comprising:
- a) a frame;
- b) a seat carried on said frame;
- c) downwardly pivotal leg supports attached to said frame;
- d) a backrest attached to said frame, said backrest being adjustable relative to said seat and including a mounting plate with a pad to engage the user's back hinged to said mounting plate, said pad being pivotal to change the orientation of the pad and the position of the upper end of the pad relative to the lower end of the pad;
- and
- e) an alarm activated when the user changes position so that the pressure exerted by the user on said backrest pad or the angle of said backrest pad is above or below a preset range.

- said pad being pivotal to change the orientation of the pad and the position of the upper end of the pad relative to the lower end of the pad;
- d) a user perceivable alarm;
- e) a first sensor associated with said backrest to sense the pressure exerted by the user on said backrest pad, said first sensor activating said alarm when the user changes position so that said pressure is above or below a preset range;
- f) a second sensor associated with said backrest to sense the angle of said backrest pad, said second sensor activating said alarm when the user changes position so that said angle is above or below a preset range;
- and
- g) downwardly pivotal leg supports attached to said frame, said leg supports being generally horizontal when in an unstressed position.
