An exercise system including a tower and a translatable and rotatable display is disclosed. The tower is a free-standing unit and includes a mast that supports the display at a sufficient height or elevation, for example above a front panel of the system's housing. A carriage assembly couples the display to the mast to enable translation of the display between two positions, and the display mount is further configured to enable rotation of the display between a portrait orientation and an landscape orientation when the display is in the second position. In some embodiments, rotation of the display is substantially inhibited by the system's housing, for example the front panel, when the display is in the first position.

A weight apparatus includes a handle, first and second anchorages mounted to first and second ends of the handle, respectively, the handle and the first and second anchorages having an axially extending opening, first and second rods axially movable inside the axially extending opening and adapted to be moved axially relative to the axially extending opening in opposite directions upon rotation of first and second pinion gears in the first and second anchorages, respectively, that engage with first and second racks on the first and second rods, respectively, and a lock having a locked condition in which rotation of the first and second pinion gears is prevented and an unlocked condition in which rotation of the first and second pinion gears is permitted.

An exercise machine may include a frame, a resistance mechanism supported by the frame, first and second pull cables supported by the frame and linked to the resistance mechanism, a power rack attached to the frame, first and second handles selectively attachable to the first and second pull cable, and first and second pulleys. The power rack includes upright posts configured to have barbell holders adjustably attached thereto such that the barbell holders are configured to be adjusted in various positions between highest positions and lowest positions on the upright posts. The pulleys are configured to selectively receive the pull cables to enable the pull cables to be selectively attached to a barbell to assist or hinder a user in lifting the barbell in a combined cableand free weight workout, the pull cables decoupled from the pulleys for cable workouts.

A dumbbell and barbell supporting system includes two tables movable toward and away from each other and each having a plate, a casing and a bracket disposed on each of the plates and the bracket being movable and rotatable relative to the casing, two dumbbells disposed on the tables and each including two weight members and two weight elements disposed on the bracket and the casing, and two handlebars engageable with the weight members and the weight elements, the weigh members are movable toward each other, and the weight elements also movable toward each other, and a longitudinal bar is engageable with the weight members and the weight elements for acting as a barbell device.

An improved kettlebell is provided. More specifically the improved kettlebell may include a frame with a holding portion and a base portion. The improved kettlebell may further include a weighted assembly including a first weighted component and a second weighted component. The weighted assembly may be coupled to the base portion of the frame through a fastener. Through the same fastener, the first weighted component may also be coupled with the second weighted component forming the weighted assembly. The weighted components may be manufactured to a variety of different weights, thus allowing users to adjust the weightlifting difficulty.
