Abstract
A core strengthening device includes a tray and a ball. The tray has first and second opposing sides. The first side of the tray has a recess formed therein. A ball is selectively positionable at least partially within the recess in the tray. The ball has a first hemisphere and a second hemisphere. The first hemisphere has a first radius and the second hemisphere has a second radius that is different than the first radius. The core strengthening device provides instability to exercises, which requires a user's core muscles to work harder to perform the exercises and maintain balance, which strengthens the user's core muscles.
Claims16
A core strengthening device, comprising:
- a tray having a first side and an opposing second side, the first side having multiple recesses defined therein where the multiple recesses are closed with respect to the opposing second side;
- a ball selectively positionable at least partially within one of the multiple recesses in the tray, the ball having a first hemisphere and a second hemisphere, the first hemisphere having a first radius and the second hemisphere having a second radius that is different than the first radius;
- wherein one of the first hemisphere and second hemisphere have an apex and a height measured at the apex, wherein the height of the second hemisphere is about equal to a depth of the one of the multiple recesses;
- wherein the ball may be selectively inverted and positioned within the tray such that either the first hemisphere or the second hemisphere projects out of the one of the multiple recesses;
- and wherein the first hemisphere and the second hemisphere engage a center of the one of the multiple recesses in the tray differently.
A core strengthening device, comprising:
- a tray having a first side and an opposing second side, the first side having a plurality of recesses defined therein where the plurality of recesses are closed with respect to the opposing second side;
- and
- a plurality of balls selectively and respectively positionable at least partially within the plurality of recesses in the tray, one or more balls of the plurality of balls having a first hemisphere and a second hemisphere, the first hemisphere having a first radius and the second hemisphere having a second radius that is different than the first radius;
- wherein the one or more balls of the plurality of balls may be selectively inverted and positioned within the tray such that either the first hemisphere or the second hemisphere projects out of a respective one or more of the plurality of recesses.
A core strengthening device, comprising:
- a tray, the tray having multiple recesses in a first side where the multiple recesses are closed with respect to an opposing second side of the tray;
- a ball, the ball comprising:
- a first hemisphere with an outer surface having a first radius;
- and
- a second hemisphere with an outer surface having a second radius, the second radius being greater than the first radius;
- wherein one of the first hemisphere and second hemisphere have an apex and a height measured at the apex, wherein the height of the second hemisphere is about equal to a depth of one of the multiple recesses;
- wherein the ball may be selectively inverted and positioned within the tray such that either the first hemisphere or the second hemisphere projects out of the one of the multiple recesses;
- and
- wherein the first hemisphere and the second hemisphere engage a center of the one of the multiple recesses in the tray differently.
