A portable, folding dog agility teeter is disclosed. The teeter has two boards which are connected by a hinge. A pair of legs are also hinged. Each board can be reversibly fixed in relation to the hinge so the longitudinal axis of each board is parallel to the other. A fulcrum is formed where the legs attach to the hinge. One of the boards is heavier than the other so the heavier board is touching the ground when no additional load is on the other board. As a dog crosses from one board to the other, the teeter moves so the lighter board touches the ground. When the dog leaves the teeter the heavier board moves to touch the ground, thereby resetting the teeter for repeated use.

The present invention relates to equipment used in the exercise of human beings. The equipment may be of a commercial type as used in gymnasiums, or of a consumer type for use in a domestic environment. Exercise apparatus configured such that a mechanical motion of a user executing an exercise activity positively affects a child on or about the apparatus are provided. The exercise apparatus may be configured to translate a mechanical motion of a user executing an exercise activity on the apparatus into a mechanical motion capable of positively affecting a child on or about the apparatus. The positive effect on the may be any one or more of moving, entertaining, occupying, distracting, stimulating, calming, settling, and educating. The mechanical motion capable of affecting a child has the effect of moving a child on or about the apparatus. The exercise apparatus may comprise child physical engagement means configured to receive the translated mechanical motion of the user so as to move a child in or about the child physical engagement means.

A mechanical advantage device includes a base, a beam pivotably connected to the base at a fulcrum between a first end of the beam and a second end of the beam, a seat at the first end of the beam, and a load at the second end of the beam. In some embodiments, the mechanical advantage device includes structure, such as a linkage, for effecting oscillation of the beam by shifting weight along the beam. The mechanical advantage device may be a single-person seesaw. In some embodiments, the mechanical advantage device may be used to move a car or to generate power.
