Apparatus for exercising a user's abdominal muscles and/or back muscles. This exercise apparatus includes a dynamic means in the form of an upper frame which is pivotally attached to a lower form. With the use of the user's abdominal and/or back muscles, the dynamic means produces a forward folding movement and a return straightening movement. A framework means in the form of a vertical frame affixed to a horizontal frame which maintains the vertical frame in an upright position supports the dynamic means. This exercise apparatus also includes a resistance means for opposing the forward folding movement and/or the return straightening movement. Various resistant means include fly wheel-fan, electro-magnetic and weight stack.
