Abstract

An exercise device having a unique asymmetrical shape with rounded ends of differing radii to provide stability and added resistance is described in this application. The exercise device allows a user to position themselves more comfortably and safer than existing exercise devices. The unique asymmetrical shape enhances results by improving safety. The shape provides a more stable structure that inhibits or eliminates tipping past a point in which a user is in control of the device position. The asymmetrical shape of the exercise device increases the resistance that can be achieved. The exercise device has an inflatable, semi-solid, or solid body with a structure having a surface with multiple curved portions that allow the device to move in a controlled manner when using the device, providing various amounts of resistance a user may apply to obtain the level of workout intensity desired.

An exercise device comprising:

a first side having a convex surface;
a second side opposing the first side, the second side having a concave surface;
a first rounded end having a first radius;
a second rounded end having a second radius;
a first arc of the first rounded end defined by the first radius;
a second arc of the second rounded end defined by the second radius;
the convex surface of the first side having an arc defined by a third radius;
wherein the first side has a first end and a second end and the first side first end is connected to the first arc and the first side second end is connected to the second arc;
