Simple Gravity Handle Return for Rowing Ergometer

I removed the top seat-rail section of the "Gravity Return Dynamic Rowing Ergometer" (demonstrated in an earlier video) so that the simplicity of the mechanics can be seen and appreciated. A U.S. Patent will be issued soon - broad claims have been allowed. I should have added in my narration that the removed seat-rail section includes a gradient adjustment so that the handle return force is adjustable and therefore unaffected by users of different weights. Also, in response to continued inquiries about the shown articulated handle, I put together several. To purchase one, contact me at [email protected]
