Exercise device having sled or wheelbarrow configuration

An exercise device, which comprises:

• (a) a frame having a front end and a rear end;
• (b) two laterally spaced handles carried on the frame adjacent the rear end of the frame, wherein the handles are selectively repositionable by a user on the frame from a first generally horizontal orientation to a second generally vertical orientation and vice versa;
• (c) at least one support surface engaging wheel carried on the frame adjacent the front end of the frame with the at least one wheel being rotatable about a substantially horizontal axis of rotation to permit rolling the frame over a support surface;
• (d) at least one support surface engaging, fore-and-aft extending skid on the frame;
• (e) at least one exercise weight member carried on the frame for adding mass to the frame, wherein the at least one exercise weight member is supported on a carriage that is movable in a fore-and-aft direction on the frame towards and away from the at least one front wheel;
• (f) wherein the at least one skid is positioned relative to the at least one wheel such that the at least one skid is lifted up out of contact with the support surface while the at least one wheel remains in contact with the support surface when the handles are positioned in their first generally horizontal orientation and a user grips the handles and elevates the rear end of the frame by lifting up on the handles to incline the frame downwardly towards the front end of the frame in the manner of a wheelbarrow such that the user is thereafter able to push forwardly on the handles to roll the frame forwardly over the support surface in the manner of a wheelbarrow;
• (g) wherein the at least one skid remains in contact with the support surface when the handles are positioned in their second generally vertical orientation such the user is thereafter able to push forwardly on the handles to slide the frame forwardly over the support surface in the manner of a sled, whereby the frame may be quickly and easily converted from use in the wheelbarrow manner to use in the sled manner and vice versa depending upon whether the user has installed the handles in their first generally horizontal orientation on the frame or in their second generally vertical orientation on the frame, respectively;
• and
• (h) a cooperable, releasable and resettable lock disposed between the carriage and the frame for retaining the carriage and the at least one exercise weight member carried thereon in a user selected, adjusted position on the frame with the user selected, adjusted position of the carriage remaining fixed relative to the frame during motion of the frame over the support surface in the wheelbarrow manner or the sled manner.
