Abstract: An exercise apparatus with base horizontal members forming a base polygon and ceiling horizontal members forming a ceiling polygon and a plurality of vertical members mounted at their lower ends to the base polygon and mounting the ceiling polygon spaced from the base polygon. A human interface permits athletes to exercise, and wheels mounted to the base polygon permit transport of the apparatus and attached equipment to a field or court. The base polygon includes two parallel skids and the human interface may be a pad permitting an athlete to push the apparatus horizontally when none or two of the wheels contact the ground. When no wheels contact the ground, the apparatus may be used in the manner of a weight rack, because the apparatus will not move along the ground without substantial force being applied.

Abstract: A portable, impact-absorbing apparatus having a striking portion, an energy-absorbing portion, and a mounting portion. The striking portion may be a padded plate and the mounting portion may be a collar that may mount to the vertical frame member of a squat rack. The energy-absorbing portion may be an insert that slides into the barrel of a hollow sleeve in which a spring is disposed. The sleeve may have slots in the top and bottom for bolts or pins, which are inserted therethrough for attachment to the insert, to define the longitudinal limits of the insert's extension.
