The present invention provides and exercise device and methods designed to assist the exerciser in all abdominal strengthening exercises by use of an adjustable resilient means to provide resistance and absorb impact for the exerciser's eccentric range of motion, while supporting or boosting exerciser's concentric range of motion. This device offers maximum support for the exerciser's hips and back through the full range of abdominal exercises. The device includes a seat member and back member pivotally connected so that the seat and back provide a horizontal platform for the exerciser's use in a full range of abdominal exercise. When the preferred embodiment is not in use, the back member and seat member fold together for ease of storage or portability. A second embodiment offers the advanced exerciser adjustable foot positioning and back member positioning and is supported by an external frame assembly. All embodiments of the device allow the exerciser to tailor each exercise workout to the desired repetition level and to combine aerobic as well as anaerobic conditioning, all based on the exerciser's relative level of fitness.

The oil pump control device according to claim 1, wherein the controller uses the kinetic characteristics obtained during operation of the electric oil pump in a certain period when the engine is restarted next time of the certain period. 6. An oil pump control device for an automatic transmission, comprising: an electric oil pump that is electrically driven to supply the automatic transmission with a hydraulic pressure; and a controller that updates the hydraulic pressure generated by the electric oil pump based on aging of a hydraulic system of the electric oil pump in an engine that is stopped automatically upon fulfillment of one of a predetermined number of running conditions of a vehicle and optimizes the hydraulic pressure by controlling the hydraulic pressure supplied to the automatic transmission based on updated hydraulic pressure. 7. A control method of an oil pump control device for an automatic transmission, comprising the steps of: setting a driving pattern of a motor for an electric oil pump that supplies a hydraulic pressure to an automatic transmission; measuring an input speed of the automatic transmission; and correcting the driving pattern based on the input speed of the automatic transmission and the hydraulic pressure generated by the electric oil pump. 8. The method according to claim 7, wherein the oil pump control device repeatedly performs the control method. 9. The method according to claim 7, wherein the electric oil pump is operated according to the driving pattern such that a difference between input speed and output speed of the automatic transmission falls within a predetermined range. 10. The method according to claim 7, wherein the driving pattern of the motor is set as a duty ratio. 11. The method according to claim 7, wherein the driving pattern of the motor is set by variable-voltage control. 12. The method according to claim 7, wherein the driving pattern of the motor is set by variable-current control. 13. The method according to claim 7, wherein the input speed of the automatic transmission is measured if a throttle is fully closed.
