The device provides a compact and lightweight form of exercise equipment that is easy to carry and easy to store. The device can be used with various fixtures, and also with a second handle fixed to the pull-cord, to allow the user to perform a wide range of exercises. Preferably the exercise device transmits exercise data to an external device that provides feedback and guidance to the user.A resistance mechanism for exercise apparatus allows a pull-cord to be coupled to a resistance element such that pulling the pull-cord from the mechanism causes the resistance element to rotate. A drive element is driven by a frictional force between the drive element and the pull-cord. The resistance element is coupled to the drive element by a transmission."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hand-held exercise apparatus and resistance mechanism for exercise apparatus","description":"A hand-held exercise device comprises a frame, a handle attached to the frame, a spool element pivotally mounted to the frame, a pull-cord movable between a wound configuration in which the pull-cord ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9731157","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
