Asymmetric Roll Out Training Device for Unilateral Abdominal Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abdominal rollers are ineffective in promoting unilateral abdominal muscle development and can be unstable, increasing the risk of injury, especially for untrained individuals.
Innovation Solution
A training device with a handle arrangement featuring distinct grip zones for each hand and a rolling arrangement with approximate axisymmetric elements, allowing for asymmetric roll-out exercises that target anterolateral abdominal muscles unilaterally while maintaining stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a common abdominal roller with symmetric handle arrangement is used, then the device is simple and stable, but it cannot effectively promote unilateral abdominal muscle development
Solution Approach 1:
The patent applies asymmetry by configuring the rolling arrangement with a first rolling element having a first diameter and a second rolling element having a second diameter that is different from the first diameter. This asymmetric configuration causes the handle arrangement to follow an asymmetric path during rolling, enabling unilateral abdominal muscle development while maintaining device simplicity
2Productivity
If the rolling arrangement is made unstable to promote higher abdominal muscle activation, then muscle engagement increases, but the risk of injury increases for untrained individuals
Solution Approach 1:
The patent changes the parameter of rolling element diameters to create controlled asymmetry. This allows the device to provide sufficient challenge for muscle activation while maintaining stability through the predictable asymmetric rolling path, reducing injury risk compared to completely unstable configurations

AI summary
The present invention relates to an advanced training device to target abdominal muscles by enabling asymmetric roll out exercise routines. The fitness industry continues to evolve, with a growing emphasis on core strengthening exercises. Abdominal rollers have been widely used for abdominal workouts, but there is a need for exercise routines that safely and effectively activate specific muscles unilaterally, in particular rectus abdominus muscles, external oblique muscles and internal oblique muscles. The present invention offers a stable and unique training device for asymmetric roll out exercise routines along a defined circular path of roll out with a high level of control for the user to effectively target abdominal muscles unilaterally.
