Disclosed herein is a resistance exercise device and methods of using the same. In one embodiment, a resistance exercise device is disclosed comprising a quarter-wheel, a means for attaching resistance to said quarter-wheel, a support means attached to the axis of the quarter-wheel, whereby a user can perform core exercise while moving in a direction parallel to the line of resistance.

Automatic salmon ladder training devices are provided. An automatic salmon ladder training device may include a frame and a rotation assembly. The rotation assembly may include a plurality of rotation subassemblies. The plurality of rotation subassemblies may each include a chain rotatably engaged by the rotation subassembly, a rung fixedly connected to the chain, and a fixed rung fixedly connected to the frame. Each of the rotation subassemblies are configured to rotate in concert with one another. For example, a left rotation subassembly and a right rotation subassembly may be configured to rotate in concert with one another.

An exercise machine creates a simulated continuous resisted climbing motion. The machine includes a floor- or ground-contacting base frame and two or more substantially vertically oriented uprights, wherein at least one upright is rigidly connected to the base frame. The machine further includes two handles and two foot pedals, each handle and each foot pedal being movably engaged with an upright for linear reciprocating motion along the upright. The handles and foot pedals are interconnected so that they move in unison. An adjustable resistance mechanism is operatively connected to the interconnection of the handles and foot pedals to provide adjustable resistance for the simulated continuous climbing motion.

A pedal slider assembly that allows for a normal pedal affixed to a normal bicycle to slide laterally outwardly away from the bicycle frame and back inwardly towards the bicycle frame allowing the rider to find their bodies natural pedal placement as it travels through the rotational pedaling path based on their specific skeletal structure restrictions, (those being the width of an individual's hips, knees, and ankles) as those positions dictate the center line of the user and as those positions are directly affected by the pedal relationship to the center line of the bicycle frame, additionally there is a multitude of lateral movement length options for the rider to utilize to garner specific exercise benefits.

An adjustable resistance mechanism may be operatively connected to the interconnection of the handles and foot pedals to provide adjustable resistance for the simulated continuous climbing motion.

According to one example, an exercise system includes a base, a vertical housing extending vertically outward from the base, a first weighted touchpoint moveably coupled to the vertical housing, a second weighted touchpoint moveably coupled to the vertical housing, and one or more weight systems configured to provide weight to the weighted touchpoints. The exercise system further includes a control system that determines randomized workouts that include a random selection of a muscle group, a weight amount, a weight differential, a number of sets of an exercise, and/or a number of repetitions in the set. The control system may also cause the weight system to adjust the weight of the weighted touchpoints based on the randomized workout.

A stationary bike capable of leaning of tilting side to side during use is described. The stationary bike has a fixed frame portion and moving frame portion which is pivotally mounted on the fixed frame portion, at two spaced apart pivot locations, to allow the moving frame to pivot about a pivot axis defined by the two spaced apart pivot locations. The pivotal action of the bike may be resisted, such as by a damper. The tilt-enabled bike is equipped with a tilt disabling mechanism, e.g., a locking mechanism configured to selectively and operatively engage the moving and the fixed frame to disable the relative movement (i.e. the pivoting) of the moving frame.
