Plyometric box

A plyometric box, comprising:

• a platform;
• and
• a first sidewall and a second sidewall rotationally fixed with respect to each other, the first sidewall and the second sidewall extending downwardly from the platform, wherein the first sidewall includes a first side, an opposed second side, and a first stacking rib on an interior surface of the first sidewall proximate the first side;
• wherein the first stacking rib extends downwardly from the platform along the first sidewall and has a vertically-extending inner edge that is angled inwardly and upwardly with respect to a vertical direction;
• wherein the first stacking rib has a bottom surface extending outwardly into an interior of the plyometric box, and wherein the bottom surface of the first stacking rib is spaced upwardly from a bottom edge of the first sidewall;
• and
• wherein the first sidewall further includes a plurality of vertical wall support ribs, and wherein the first stacking rib extends outwardly into the interior of the plyometric box beyond a first vertical wall support rib of the plurality of vertical wall support ribs.

A plyometric box, comprising:

• a platform;
• and
• a first sidewall and a second sidewall rotationally fixed with respect to each other and arranged at an angle to each other, the first sidewall and the second sidewall extending downwardly from the platform, wherein the first sidewall includes a first side, an opposed second side, an upwardly facing shoulder at a top edge of the first sidewall, and a lip located above the upwardly facing shoulder extending inwardly from the top edge beneath the platform;
• and
• wherein a bottom surface of a peripheral edge of the platform is seated on the lip of the first sidewall.

A plyometric box, comprising:

• a platform;
• a first sidewall and a second sidewall, wherein the second sidewall is adjacent to the first sidewall;
• wherein the first sidewall and the second sidewall extend downwardly from the platform;
• the first sidewall including a bottom edge, a top edge, a first stacking rib on an interior surface of the first sidewall, wherein the first stacking rib has a bottom surface extending outwardly into an interior of the plyometric box, and wherein the bottom surface of the first stacking rib is spaced upwardly from the bottom edge of the first sidewall;
• wherein the first sidewall further includes a plurality of vertical wall support ribs, and wherein a fillet is positioned at an intersection of the bottom surface of the first stacking rib and an interior edge of a first vertical wall support rib of the plurality of vertical wall support ribs, wherein the fillet has a first radius;
• wherein a top peripheral edge of the platform is rounded over with a second radius;
• and
• wherein the first radius is substantially the same as the second radius.
