Exercise apparatus with resilient foot support

An attachment for an exerciser of the type including a movable body support disposed on a frame assembly in a position to support the body of an exercising person in a position which allows the body of the exercising person to move with the movable body support in a direction towards or away from the attachment, and parallel to or at an acute angle with respect to a ground support for the frame assembly, while enabling the feet of the exercising person to be free to be moved with respect to the movable body support,

• said attachment comprising a movable foot support including:
• a rigid frame including a connector structure constructed and arranged to connect the rigid frame to the frame assembly of the exerciser such that the rigid frame extends in a direction that is not parallel to the ground support;
• a replaceable sheet assembly configured to removably and reattachably engage the rigid frame to provide an associated resilience for the resilient foot support system;
• and
• a strap having a releasable connection end, the strap being constructed and arranged to be wrapped around the rigid frame to allow the connection end of the strap to releasably connect the strap around the rigid frame;
• wherein said replaceable sheet assembly is constructed and arranged to yield resiliently in response to the engagement of the feet of the exercising person and to provide, as a result of the resilient yielding, a bouncing movement to the person as the moveable body support moves parallel to or at an acute angle with respect to the ground support.

An exerciser comprising:

• a frame assembly including a track;
• a movable body support disposed on said track and constructed and arranged to support the body of an exercising person in a position which allows the body of the exercising person to move with the movable body support while enabling the feet of the exercising person to be free to be moved with respect to said movable body support, said movable body support being moveable on said track in a first direction away from a movable foot support and in a second direction toward said movable foot support, whereby the movable body support is configured to move along said track parallel to or at an acute angle with respect to a ground support for the frame assembly;
• the movable foot support being constructed and arranged to be engaged by the feet of the exercising person supported on said movable body support, said moveable foot support comprising:
• (a) a rigid frame including a connector structure constructed and arranged to connect the rigid frame to the frame assembly of the exerciser such that the rigid frame extends in a direction that is not parallel to the ground support;
• (b) a replaceable sheet assembly configured to removably and reattachably engage the rigid frame to provide an associated resilience for the replaceable sheet assembly, wherein said replaceable sheet assembly includes resilient structure capable of providing a spring force in response to the engagement of the feet of the exercising person moving with the movable body support in said second direction and to establish, as a result of the spring force, a return movement by the movable foot support in said first direction which can be translated by the exercising person into a movement of said movable body support in said first direction, parallel to or at an acute angle with respect to the ground support;
• and
• (c) a strap having a releasable connection end, the strap being constructed and arranged to be wrapped around the rigid frame to allow the connection end of the strap to releasably connect the strap around the rigid frame.
