ABSTRACT:
A ladder for a children's play structure comprises spaced-apart, elongate side members extending from a first end of the ladder to a second end thereof. A plurality of rungs extend perpendicularly between the side members, adjacent rungs having a distance therebetween which increases from the first end of the ladder to the second end. A third elongate member, parallel to the side members and midway therebetween, extends substantially from the first end of the ladder to the second end. The third member is outwardly spaced, away from the rungs, such that a child climbing the ladder from the first end towards the second end, having his feet on the rungs and grasping the third member, exercises his arm and torso muscles in lifting his body.
