Glider exercise machines now popular as aerobic exercising devices engaging muscle groups of both the upper and lower body are improved to provide anaerobic exercise, and aerobic workouts for users in excellent physical condition. Apparatus designed to provide more than the leveraged body weight of a user may include deadweights attached below the seat of a user. In certain embodiments, a glider may have a mechanical resistor positioned between the beam supporting the seat, and the lever lifting the beam away from the frame in response to actuation by a user pulling on handlebars and stepping on pedals. Resistors may also be connected between parts of the moveable assembly. Resistors may include hydraulic dashpots, springs, elastic straps, gas cylinders, and the like, secured between a stationary frame and a selected part of a moveable assembly, such as, for example, the beam supporting the seat or saddle, the lever lifting the seat, or the lever attached to the handlebar.
