Hyperextension Exercise Saddle for Abdominal Muscle Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices and techniques face challenges in effectively targeting and strengthening abdominal muscles without risking injury to the spine, due to the antagonistic muscle groups and difficulty in achieving full range of motion during exercises like sit-ups and crunches.
Innovation Solution
An exercise machine with a saddle and lower body support assembly that allows for hyperextension of the spine, supports the lumbar region, and inhibits contraction of antagonistic muscle groups like hip flexors, enabling full engagement and extension of abdominal muscles while minimizing spinal strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional sit-up or crunch exercises are performed to strengthen abdominal muscles, then muscle engagement is achieved, but spinal injury risk increases due to lumbar strain
Solution Approach 1:
The saddle device acts as an intermediary between the user and the exercise motion. It provides a supported platform that allows hyperextension of the spine while preventing direct lumbar strain. The saddle supports the user's body weight and enables abdominal muscle engagement without transmitting harmful forces to the spine.
Solution Approach 2:
The exercise machine divides the body into supported and free-moving segments. The saddle supports the lumbar region and upper body, while the legs remain free to move. This segmentation allows the abdominal muscles to work against gravity and resistance without compromising spinal integrity.
2Productivity
If full range of motion is achieved during abdominal exercises, then muscle recruitment is maximized, but antagonistic muscle groups like hip flexors interfere with abdominal engagement
Solution Approach 1:
The saddle device performs preliminary action by pre-positioning the user in a hyperextended state with the lumbar region supported. This preliminary positioning inhibits hip flexor activation before the abdominal exercise begins, creating optimal conditions for isolated abdominal muscle engagement.
Solution Approach 2:
The saddle provides localized support specifically to the lumbar region, creating a zone of reduced gravitational pull and inhibited muscle activation. This local quality change allows the abdominal muscles to engage fully without interference from antagonistic hip flexors.
3Productivity
If the torso region is manipulated to target abdominal muscles, then exercise effectiveness increases, but equipment complexity increases compared to simple body weight exercises
Solution Approach 1:
The saddle device serves multiple functions: it supports the user's body weight, enables hyperextension of the spine, provides lumbar support, and facilitates abdominal muscle engagement. This multi-functionality achieves exercise effectiveness without requiring complex mechanical systems.
Solution Approach 2:
The device allows the user to perform the exercise using their own body weight and gravity as the primary resistance mechanism. The saddle simply provides support and positioning, eliminating the need for complex weight stacks, pulleys, or mechanical resistance systems.

AI summary
A method and device for use in resistance training is provided. A first version includes a saddle that supports the lower back while an exercise subject extends and then hyper-extends the subject's vertebral column. A second version includes a foot bar against which the subject applies force from the foot or lower leg while extending, hyperextending the subject's vertebral column. A third version includes a knee bar against which the subject pulls while extending, hyperextending and contracting the subject's vertebral column.
