Stride adjustment program

In an elliptical step exercise apparatus where stride length can be varied the various user programs can take advantage of this feature to provide for an enhanced workout. A control system can be used to implement a preprogrammed exercise routine such as a hill program where stride is shortened as the user goes up a simulated hill and lengthened as the user goes down the hill. In an interval training program, stride length can be increased and decreased at periodic intervals. In a cross training program, stride length can be decreased when the user is pedaling backwards and increased when the user is pedaling forwards.

Elliptical exercise machine with adjustable stride length

An elliptical exercise machine and methods for using the machine where the horizontal length of the stride of the ellipse can be adjusted by the user without the user having to alter the vertical dimension of the ellipse by an equivalent amount. The machine provides for alteration using an inverted pendulum arm which is driven by rotation of a rail and which in turn drives a footskate on the rail. The position for the driving of the inverted pendulum arm by the rail and the driving of the footskate by the inverted pendulum arm are adjustable relative to each other so as to provide for multiple different stride lengths in exercising. The machine may allow for this adjustment to occur during the performance of an exercise routine.

Elliptical step distance measurement

In an elliptical step exercise apparatus distance traveled can be approximated by determining the portion of the ellipse traversed by a foot pedal where the user applies force to the pedal. This portion can be considered equivalent to the amount of foot travel on a treadmill and modified as a function of speed to simulate the gait of a user at various speeds so as to provide an approximation of the distance traveled by a user as if he were running on a treadmill. This process can be further modified for use with an elliptical exercise apparatus where the stride length can be changed such that the simulated distance will be increased with increased stride length.

Leg Stretching Machine For Simultaneously Stretching All Stride Muscles And Method Of Using

InactiveUS20130225378A1Overcomes stretching fatigueStretch excessivelySpace saving gamesStiltsStride lengthEngineering
A muscle-stretching machine designed to provide the user with an easy method of functional and dynamic stretching and also provide the user with flexibility feedback information as to the performance of the stretch, with regards to the included angle between the two legs. A user of the muscle stretching machine can set the roller pad along any point along the back of the user's leg and set the angle the roller pad makes with the floor, so that the angle exceeds the users stride length. The user then lies on their back on the cushioned surface; places one leg on the roller pad and the other leg is allowed to hang down. If the roller pad is set at an angle that exceeds the users stride length, then the leg not on the pad will not contact the floor. As a result, when the free leg drops all the muscles in the user's stride are stretched.

Adjustable elliptical exercise machine

The present invention relates to a standup exercise apparatus that simulates walking, jogging and climbing with arm exercise. More particularly, the present invention relates to an exercise machine having separately supported pedals for the feet and arm exercise coordinated with the motion of the feet. Elliptical cross trainers guide the feet along a generally elliptical shaped curve to simulate the motions of jogging and climbing. Existing elliptical cross trainers often use excessive pedal articulation which can overwork the ankle to achieve a longer stride. The present invention is an improved elliptical exercise machine capable of extended exercise with less pedal articulation that is more ankle friendly. One end of a foot support member has a pedal which follows elliptical motion while the other end is guided by a drive link to drive an alternator and flywheel. The resulting pedal motion is foot friendly. Handles are coordinated with the foot support members for arm exercise. Both the stride length and orientation of the pedal ellipse are adjustable.
