An adjustable exercise machine for performing resistance exercises comprises a base and an upper frame including front and back end stationary exercise platforms, and a movable exercise platform that reciprocates between the stationary platforms. A plurality of biasing members is selectable by an exerciser via selector knobs to generate a bias force against the movable platform. A plurality of pivotable lift supports are connected between the base and the upper frame. Front and back actuators are connected between the base and the lift supports by lifting yokes to selectively raise and lower the front and back ends of the machine. The movable platform may be connected to move along the exercise machine by trolley wheel assemblies. A plurality of travel limit decelerators mounted on the rails engage and rapidly decelerates the movable platform as it reaches its limits of travel on the rails.

An End Platform for an Exercise Machine for increased support of an exerciser's spine, neck and head which allows for an expanded scope of exercises that cannot otherwise be performed on the machine without the improved platform. The End Platform for an Exercise Machine generally includes a novel, ergonomically improved stationary platform affixed to at least one opposed end of a substantially longitudinal exercise machine that includes at least a resistance biased reciprocating platform. The improved end platform provides for increased support of exercisers' spine, neck and head, thereby allowing for an expanded scope of exercises that cannot otherwise be performed on the machine without the improved platform, and further provides for the attachment of new and novel exercise equipment accessories to the exercise machine.

A virtual reality (VR) system includes a VR display and a VR movement apparatus that includes hand user interfaces (UIs) and foot UIs that can support the hands, feet, and total weight of a user. The VR movement apparatus allow the user's hands and feet to move in 3-dimensional space that include vertical, lateral, and fore-aft direction movements. A computer running VR software coordinate and synchronizes the VR movement apparatus and the VR display to provide system users with simulated activities in a VR environment.

The present invention relates to a device for physical exercise comprising a pair of skis (2) having a top side and a bottom side, a frame (5), two pendulate arms (19), each of the pendulate arms has an upper end rotatably connected to the frame about a rotational axis, and a lower end pivotably connected to one of the skis, and at least one resistance unit (13, 15) connected to the pendulate arms. The device comprises at least one support parts (1;29;30) located below the skis respectively, and two movable elements (20;26;28) connected to the bottom sides of the skis respectively, and each of the movable elements are arranged linearly movable along one of the support parts.

An exercise machine that enables a user to exercise extensor and flexor muscles. The exercise machine includes a base with a rolling cylinder configured to roll from a front end of the base to a rear end of the base. The exercise machine further includes a slant board resting on the rolling cylinder.

A stationary exercise apparatus includes two connecting members each having an upper end guided to move along a circular path and a lower end coupled to a swing member, so that when the upper end moves along the circular path, the lower end moves along an arc-shaped path. Two supporting members are configured to support a user's feet, which are coupled between the upper end and the lower end of the respective connecting members and movable along a closed path. Two control members each is arranged between the corresponding supporting member and the corresponding swing member for guiding the second portion of the corresponding supporting member along a predetermined path, so that an angle formed between each supporting member and the corresponding connecting member varies as the corresponding swing member moves along the arc-shaped path between a first endpoint and a second endpoint.

An exercise device includes spaced-apart exercise members engageable by appendages of an exerciser and moveable in opposed directions, a body support member for supporting an exerciser and a platform below the body support member. A synchronizing drive system connects the exercise members with the body support member for moving the body support member in opposite directions relative to the platform by movement of the exercise members in opposite directions, respectively.
