1. A walking frame, comprising:
a wishbone-shaped support defining a front plane of the walking frame, the wishbone-shaped support comprising:
a column extending a height in the front plane from a first end of the column to a second end of the column;
a first leg connected to the column and branching in a first direction away from the column in the front plane to a first side of the walking frame; and
a second leg connected to the column and branching in a second direction away from the column in the front plane to a second side of the walking frame, wherein the second side is disposed opposite the first side;
a handlebar comprising a first tube end disposed on the first side of the walking frame and a second tube end disposed on the second side of the walking frame, wherein the handlebar is operatively connected to the column adjacent the second end of the column; and
a first grip tube connected to the first tube end on the first side, the first grip tube comprising a first rail section axially aligned with the first tube end, a support rail section connected to the first rail section and bent at a first angle relative to the first rail section disposing the support rail section in an inclined plane, and a second rail section connected to the support rail section and bent at second angle relative to the first angle, wherein the inclined plane intersects with the front plane, and is angled from a lowest point adjacent the first rail section to a highest point adjacent the second rail section.
