An exercise device (10) includes a base (11) comprising a rigid piece of material which may be placed flat on a floor. An isokinetic resistance unit (12) is pivotally connected at a lower end to the base, with a harness (13) connected to an upper end of the resistance unit. A user uses the device by attaching the harness (13) preferably around the waist and, while standing on the base (11), bending to a squatting position and then returning to an upright position. The resistance unit (12) comprises a cylinder (30) and piston (31) arrangement which provides resistance as the user moves from the squatting position to the upright position. The resistance is provided through a negative pressure developed in a working chamber (38) defined between the piston (31) and a first end of the cylinder (30).

1. An exercise apparatus for providing resistance as a user straightens their legs to move from a bent-leg standing position to a second standing position, the distance between the level of the user's feet and the user's waist in the second standing position defining a first dimension and the distance between the level of the user's feet and the user's waist in the bent-leg position defining a second dimension, the apparatus comprising:(a) a substantially rigid base having an upper surface with a first support area and a second support area, the first support area being spaced apart from the second support area along a base axis; (b) an isokinetic resistance unit providing isokinetic resistance as it moves from a retracted length to an extended length, the extended length being substantially equal to the first dimension and the retracted length being substantially equal to the second dimension; (c) a lower pivot connection connecting a lower end of the isokinetic resistance unit to the base at a location between the first support area and the second support area, the lower pivot connection having a pivot axis about which the isokinetic resistance unit may pivot; and (d) a waist harness connected to an upper end of the isokinetic resistance unit, the waist harness adapted to extend around the user's waist.
