A fitness-equipment storage bench for use in aiding or supplementing a physical activity in a physical-activity environment whilst enabling storage of fitness equipment, the fitness-equipment storage bench comprising a cuboidal or substantially cuboidal body having first and second ends, two opposing sides between the first and second ends, a top and a bottom; at least one recess formed in one of the said sides; at least one cantilevered bar support in the recess for supporting a dumbbell such that a grip axis of the dumbbell is received entirely within the recess; at least one rotatable element at or adjacent to the first end or the second end to facilitate reorientation of the bench; a pivotable user back support on the top of the cuboidal body; and a stay associated with the back support to hold the back support in at least one raised condition.

Exercise equipment for at least pulling and pushing exercises comprises an elastic tubular band covered by a flexible material covering, for example, of nylon which is threaded through an O-ring grommet and holes in first and second straps threaded through first and second handles proximate to one another when gripped by a user. The exercise equipment may be used with a safety door attachment that comprises a safety loop for looping around a door handle or knob. The safety loop is stitched to a loop threaded through a plastic spindle of a foam door stop used on one side of a closed door. A further loop extends from the plastic spindle to the other closed side of the door and is adapted to receive the exercise equipment through the further loop. A series of isometric pulling and pushing exercises, trunk rotation among other exercises are disclosed and various accessories which may be used for warm up, relieving pain and for exercise including a D-ring embodiment for use with known exercise equipment.

A dual functional robot for collecting rollable objects capable of an upright position and a horizontal position, in which the robot includes a way to propel the robot; a way to control propulsion of the robot; a way to locate the rollable object; a way to collect the rollable object; a way to store the rollable object; a way to support the robot and allow the robot to move across a surface in a low-friction manner; and a way to stably reorient the robot from the horizontal position into the upright position.

A column-type combination climbing exercise machine mainly includes: the bottom end of a stand frame provided with a ground seat; a column is locked with the stand frame through a locking component; two sliding chutes are respectively disposed at the opposite left and right sides of the column; two sliding seats are correspondingly disposed in the two sliding chute, each sliding seat is adjacent to the top thereof, and a handle and a pedal are respectively disposed at the two ends of the bottom; a first linkage mechanism is connected with the two sliding seats to form a mutually opposite lift-fall and linkage action; a damper is assembled in the ground seat; two connectors are respectively disposed in the two sliding a seat; and a second linkage mechanism makes the damper and the two sliding seats in a linkage relationship.

A functional training rig kit includes a box and a plurality of components adapted to fit within the box. At least some of the components and the box include elements by which the components are adapted to be attached to the outside of the box to provide at least one functional training rig attached to the outside of the box.

An adjustable rehabilitation and exercise device, including a rotary member having a plurality of elongated and spaced apart elongated open-ended slots defined thereon, each slot including a plurality of enlargements along the length thereof. A mount is selectively and movably positionable on a selected one of the slots of the rotary member to select an angular location of the mount. The mount includes a slide member movably positionable along the selected slot to a selected radial location along the selected slot to select a radial location of the mount relative to the hub of the rotary member. The mount includes a movable pin having an enlarged head. The pin is positionable to selectively engage the enlarged head thereof within the enlargements of the slot so as to lock the position of the mount along the slot. A patient engagement member is connectable to the mount and movable with the mount.

A low friction rehabilitation board having an integral band retaining feature is described. The rehabilitation board may have a coefficient of static friction of no more than about 0.5 and in some embodiments no more than about 0.06. The rehabilitation board has a plurality of band retaining feature configured along one or both ends and may be an integral band retaining features being formed in the board. Additionally, the rehabilitation may include one or more band retaining features on one or both sides of the board. The unique configuration of the band retaining features enables rehabilitation method heretofore not possible with a single board. Resistance bands may be retained in the band retaining features and coupled to a user's limb, such as a foot or ankle, to resist motion, such as sliding or extending the foot along the low friction surface of the rehabilitation board.

Embodiments are provided for a mobile fitness center that is capable of attaching to a vehicle to provide an on-site fitness center that is capable of being used in urban environments and on the side of streets without disconnecting to a vehicle. In some embodiments the mobile fitness center has a wedge-shaped front end that provides for expanded room inside for workout activities. Further, in some embodiments the mobile fitness center includes a side door, allowing access to the mobile fitness center from the side of a busy street.
