Rotational exercise device

Abstract

A rotational-exercise-device (device) is disclosed. In some exemplary embodiments, the device may comprise: a handle-member and a rotational-member. The handle-member may be an elongate member. The handle-member may further comprise a first-handle-member and a second-handle-member. The first-handle-member may removably attach to the second-handle-member. The handle-member may include a longitudinal-axis which runs down a center-longitude of the handle-member. The rotational-member may be a substantially ovoid shape. The rotational-member may comprise a hollow cylindrical cavity passing through a longitude-center of the rotational-member. A portion of the handle-member may pass removably through the longitude-center of the rotational-member. The rotational-member may be configured to rotate about this portion. When assembled and in use, a user may grip each handle-member (or portion thereof) and perform various exercises by placing some of the user's weight upon the rotational-member, while the user causes the rotational-member to rotate against some surface, such as a floor and / or wall.

AI Technical Summary

Benefits of technology

The present invention relates to a rotational-exercise-device that includes a rotational-member and a handle-member, with the handle-member being comfortable for the user to grip. The device may also include multiple rotational-members, each with a unique weight and / or exterior surface curvature. The user may select different rotational-members to perform more difficult exercise routines. The technical effects include improved user comfort and flexibility in performing various exercise routines with a rotational-exercise-device.

Problems solved by technology

The problems of a person performing sit-ups and / or crunches without the assistance of any other device are well known in the related art and result in at least four problems.

The first problem associated with traditional sit-ups and crunches is the problem of even getting into a reclined or supine position on the floor.

For many people the floor location and getting into such a supine or reclined position on the floor is problematic.

For example, elderly people can have difficulty in getting into a reclined or supine position on the floor and then transitioning back again off the floor from such a position.

The second problem that traditional sit-ups and crunches create is a possibility of stress, strain, discomfort, and pain in the lower back region because the lower back region is not supported when doing traditional sit-ups and crunches.

A third problem that traditional sit-ups and crunches create is a possibility of stress, strain, discomfort, and pain in the neck because while the sit-ups or crunches are being performed gravity continually pulls upon the person's head which can cause stress, strain, discomfort, and pain in the neck region.

In addition, headaches are also a common problem stemming from an unsupported head during sit-ups and / or crunches exercises.

And a fourth problem arises because as a person becomes more in-shape, i.e. in better physical condition, the person must perform increasingly more repetitions of sit-ups and / or crunches to properly exercise the now stronger abdominal muscles which becomes time consuming.

This occurs because the resistance which generates the abdominal exercise in sit-ups and crunches is merely the weight of the person performing the exercise acting against gravity and thus the effectiveness of traditional sit-ups and crunches are limited by the person's own body weight, unless some artificial weights are added or some form of increased resistance beyond a person's own body weight is provided.

However, current ab rollers suffer a problem in that they are not modular.
