Exercise apparatus (11) has a platform (12) divided into a back-rest element (18) and a seat portion (19). The back-rest element (18) is pivotably mounted in the platform (12) about a pivot point (21). The platform (12) has legs (13, 14) at each end thereof, each said leg (13, 14) having an upper part (22) and a lower part (23) pivotably connected thereto about a further pivot point (25). By varying the position of the back-rest element (18) relative to the platform (12), and the position of the lower leg portions (23) relative to the upper leg portions (22), the exercise apparatus (11) can be made to assume each of a range of configurations comprising bench, step, intermediate incline, high and low seated incline and chair configurations.
