A resistance system for an exercise device includes a plurality of cord plates which may be selectively engaged by one or more pins which may include an engagement lock. One or more of the cord plates may be received by a pin with each cord plate that is received by a pin being secured relative to a frame. A cord plate that has received a pin is engaged and a cord plate that is not received by a pin is disengaged. A carriage may be provided which receives a plurality of elastic cords which may be attached to the cord plates. The carriage may be displaced relative to a base frame, to provide elongation of the elastic cords coupled to engaged cord plates and no elongation of the cords coupled to the disengaged cord plates which provide a selective resistance for a user.
