A manual powered treadmill includes a frame; a front shaft assembly coupled to the frame; a rear shaft assembly coupled to the frame; an intermediate shaft coupled to the frame, the intermediate shaft is disposed intermediate the front shaft assembly and the rear shaft assembly; a running belt disposed about the front and rear shaft assemblies, the running belt defining at least a portion of a non-planar running surface; and a safety device coupled to the intermediate shaft. The safety device is operable to substantially prevent movement of the running belt in a first direction and to permit movement of the running belt in a second direction opposite the first direction.

A non-mechanical manual combination treadmill/step deck exercise device comprises a treadmill having a strut beam frame with multiple spaced rods with equally dimensioned pipe rollers threaded thereon creating manually operated foot rotatably surface. A step deck conversion simulating a stair climbing workout comprises positioning a deck platform between opposite strut beams over said rollers. The step deck conversion unit is selectively in an operative location with treadmill in a storage location. Swing handles operative in handle assembly mounted to front exterior sides of strut beams of the treadmill foot contact surface pivoting the handles back and forth and thereby provide an arm movement simultaneously with the use of the leg exercise.

The present invention relates to systems and devices for improving of a rower's technique. In particular, the invention provides one or more clamps that can be used in conjunction with a rowing machine to provide external cues that the rower can use to monitor and correct his or her catch technique without the assistance of a coach or other person.

A stair exerciser apparatus for simulating stair climbing includes a frame, a lower shaft and an upper shaft mounted rotatably on the frame, a conveyor operatively engaged with the upper shaft and the lower shaft, a plurality of steps, a flywheel and a one-way clutch mechanism. The plurality of steps are joined to the conveyor for movement with the conveyor. The flywheel is operatively engaged with the conveyor. The one-way clutch mechanism is operatively engaged with the conveyor and the flywheel. The one-way clutch mechanism is configured to selectively couple the conveyor with the flywheel such that motion of the plurality of steps in a first step direction drives rotation of the flywheel when the one-way clutch mechanism is engaged, and the one-way clutch mechanism decouples the conveyor from the flywheel when the one-way clutch mechanism is disengaged.

A hitting extension for a body-positioning trainer is disclosed. The hitting extension has an elongate, generally flat body with first and second ends spaced from one another. The second end terminates in a rounded distal edge. A first opening formed in the body proximate to the first end allows the hitting extension to be connected to the body-positioning trainer. The body-positioning trainer restricts the movement of the arms in order to allow the user to focus on torso movement, and the hitting extension allows the user to hit a ball, or another such projectile, using the trainer. Methods for training a user in torso movement using the hitting extension are also disclosed.

A piece of exercise equipment particularly for improved strength training exercises. More particularly, the invention relates to equipment that allows the user to vary tension when performing different exercises. The present invention is specifically designed for improved exercise through the variability of a tension component for use in such exercises as the plank exercise, sit-ups, push-ups and supine pull-ups that includes a core support, a guide arm, a head support, and a foot support that work in conjunction to most optimally support the user. The core support, the head support and the foot support are all connected, supported, and elevated from the floor by a central support system.

The exercise device according to an embodiment of the present invention includes: an arm pivotably connected to the frame and rotatable wherein the arm comprises an arm pivot axis aligned with a user's hip joint; a leg pad pivotably connected to a lower end of the arm and configured to contact the user's leg during use, a handle connected to a lower end of the seat or to the frame and extending therefrom; an arm starting region fixing unit which is provided to fix an exercise starting section; an arm length fixing unit for adjusting the length of the arm; a seat which is configured in correspondence to a hip and a thigh of a leg of two legs of a user so as to support the hip and the thigh of the leg that is not exercising and not to support the hip nor the thigh of the other leg of the user, and thus the seat is separated from the leg pad when viewed from above and is configured to enable the exercising leg of the user to move to the back of the user from a starting pose at which the hip and the thigh of the leg that is not exercising is placed on the seat and the exercising leg is placed on the leg pad and pulled to the chest of the user. Preferably, a leg pad may be configured to contact the user's thigh during use to protect the user's knee and ankle joints while exercising. Also, the exercise device allows the user to exercise the thigh and gluteal muscles while protecting knee and ankle joints of the leg that are not exercising.

A treadmill is provided according to various embodiments herein. The treadmill includes a frame; a front shaft coupled to the frame; a rear shaft coupled to the frame; and a running belt disposed about the front and rear shafts, wherein the running belt assumes at least a portion of a curved running surface, the curved running surface having a radius of curvature of approximately 88 to 138 inches.

A multi-purpose athletic training platform exercise device is provided. A user may stand atop a platform and exercise while connected to a downward pulling source of resistance. This machine allows the user to walk forwards, backwards and side-to-side freely while still having attachment to the resistance source via a connecting means. This will activate all the muscles in the lower body while tractioning the lower back and helping to reduce pelvic tilt. The resistance may be varied during the user effort. The user is able to step off the machine to climb up or down a step, or walk up and down a ramp that may be provided.

A translatable carriage exercise machine comprising first and second spaced elongate side rails. A moveable carriage translatable along the side rails. An upper support surface on the carriage sized to support the entire posterior trunk of an adult human in supine. A plurality of elastic tension members secured to a bottom of the moveable carriage and fixable to a plurality of spring anchors. An upright footbar positioned at a machine first end. A pair of carriage pulleys fixed at a second end of the exercise apparatus with carriage ropes adjustably fixed to the moveable carriage each looped around respective carriage pulleys. A rotational resistance mechanism comprising an elongate resistance band having an extended configuration and a retracted configuration. The rotational resistance mechanism comprising a resistor comprising a load member. A user option to utilize one or more of the elastic tension members and rotational resistance mechanism during exercise.
