A crutch including an extendible, locking shaft having an upper end and a lower end; a handgrip positioned to the front of the crutch and joined to the upper end of the shaft by a connecting arm; and an underarm at a level below the level of the handgrip, whereby the user's hand is positioned above the level of the user's underarm when using the crutch, to thereby pull upward on the handgrip during forward movement, instead of a pressing downward on the handgrip and underarm support.
