Exercise machine with unstable user support

摘要

An unstable user support device designed for mounting on an exercise machine has a base or mounting bracket and a user support platform configured for engagement by the user and pivotally mounted on the base for pivotal movement through a limited angle about a pivot axis extending in a plane parallel to the user support platform, The pivoting movement may be a side to side tilting movement. Stops between the base and support platform control the amount of pivoting movement. This arrangement provides a degree of instability to the platform, to provide a greater challenge to the user's core muscles in balancing the platform while performing an exercise motion.
