A resistance adjustable exercise device, including a resistance assembly to provide resistance to movement, a handle assembly connected to at least a portion of the resistance assembly to move the resistance assembly in at least one of a first rotational direction and a second rotational direction, and a control unit disposed on at least a portion of the handle assembly to adjust at least one of a first resistance level and a second resistance level of the resistance assembly.

An exercise bike operable while remaining stationary on a support surface. The exercise bike includes a bicycle frame with a pedal assembly coupled to a clutch mechanism that is movable between an unlocked state in which the pedal assembly drives a wheel in a first rotational direction and rotates relative to the wheel in a second rotational direction, and a locked state in which the pedal assembly is rotationally fixed to the wheel to drive the wheel in the first rotational direction and the second rotational direction, and a handlebar assembly. The handlebar assembly is coupled to the bicycle frame and includes a handlebar and a locking mechanism. The locking mechanism is moveable between an unlocked position in which the handlebar is allowed to rotate about an axis, and a locked position in which the handlebar is restricted from rotating about the axis. A control module may move the locking mechanism and the clutch mechanism between their respective locked and unlocked states.

A manually powered treadmill includes a frame; a first rotatable element coupled to the frame; a second rotatable element coupled to the frame; a plurality of bearings coupled to the frame; a running belt at least partly supported by the plurality of bearings, where at least a portion of the running belt defines a curved running surface; and a safety device coupled to at least one of the first rotatable element and the second rotatable element. The safety device is structured to substantially prevent rotation of the at least one of the first rotatable element and the second rotatable element in a first rotational direction and permit rotation of the at least one of the first rotatable element and the second rotatable element in a second rotational direction opposite the first rotational direction.

A treadmill has a front or rear set of pulleys and a looped running belt. The pulleys rotate with the movement of the belt, e.g., when a user walks, jogs, or runs on the treadmill. The pulleys are mounted on a rotating roller tube so that the roller tube rotates with the pulleys. The roller tube is mounted on a stationary shaft using bearings on each side and a one-way device that allows the pulleys to rotate in one direction. The rotation direction corresponds to the movement of the top of the belt from the front to the rear of the treadmill. The one-way device prevents the pulleys from rotating in the opposite direction, preventing the top of the belt from moving from the rear of the treadmill to the front. The one-way device may be a sprag clutch. The treadmill may be a motor-less, curved treadmill.

An exercise machine is used to train the low back core musculature and lumbopelvic complex. The exercise machine can also be used to provide stability to the lumbar spinal column. The exercise machine includes a stationary bench substantially parallel to the floor and a rotating bench that is capable of rotating at an angle α about an axis, wherein the axis is located between the stationary bench and the rotating bench. A resistance means is used to adjust the amount of force required to move a resistance bar away from the rotating bench, while performing at least one of: a plank, a side plank, a bird-dog, a superman, a lumbar extension, a glute bridge, a single leg raise, a dual-leg raise, a bent leg raise, or a resisted push-up.

This disclosure addresses an exercise device adapted to enable the user to perform a salmon ladder exercise. The ladder includes a frame with at least one pair of support protrusions that receive an exercise bar. A bearing surface that receives the shaft of a catch array rotatably mounted in the frame. The device further includes a braking mechanism that applies a variable suppression force to the catch array shaft, the variable suppression adjusting the force required to rotate the catch array shaft in the bearing surface.

A four-bar linkage assembly exercise station that can be adjusted to various configurations to create various exercise motions having at least one adjustable operational pivot that is movable prior to operation of the machine and stationary during operation of the machine and at least one stationary adjustment pivot operatively connected to the at least one adjustable operational pivot. The stationary adjustment pivot is also operatively connected to an adjusting and latching component or assembly that can be engaged by a user prior to operation of the machine to adjust the four-bar linkage assembly exercise station to a desired configuration to create a unique exercise motion and secure the desired configuration of the adjustable four-bar linkage assembly.

An electromechanical device for rehabilitation includes pedals coupled to radially-adjustable couplings, an electric motor coupled to the pedals via the radially-adjustable couplings, and a control system including a processing device operatively coupled to the electric motor. The processing device configured to, responsive to a first trigger condition occurring, control the electric motor to operate in a passive mode by independently driving the radially-adjustable couplings rotationally coupled to the pedals. The processing device also configured to, responsive to a second trigger condition occurring, control the electric motor to operate in an active-assisted mode by measuring revolutions per minute of the radially-adjustable couplings, and cause the electric motor to drive the radially-adjustable couplings when the measured revolutions per minute satisfy a threshold condition, and responsive to a third trigger condition occurring, control the electric motor to operate in a resistive mode by providing resistance to rotation of the radially-adjustable couplings.

An exercise machine includes a shaft configured to rotate about an axis; a spool configured to receive a strap and drive rotation of the shaft about the axis in response to movement of the strap; a flywheel configured to rotate about the axis; one or more conductive coils arranged to generate magnetic fields that induce eddy currents in the flywheel; a clutch configured to engage and disengage transmission of torque between the spool and the flywheel; and a spring arranged around the axis, the spring configured to exert a return torque on the spool about the axis in response to rotation of the shaft.

A reversible resistance exercise machine for reversing the direction of applied resistance against a movable platform of an exercising machine. The exercise machine has a frame, a carriage movably positioned upon the frame, and a plurality of biasing members. A plurality of first tension connectors are accessible near the first end of the carriage and are adapted for removably attaching selected biasing members near the first end of the carriage to resist motion of the carriage in the first direction. A plurality of second tension connectors are accessible near the second end of the carriage and are adapted for removably attaching selected biasing members near the second end of the carriage to resist motion of the carriage in the second direction. A user selectable amount of force may be applied to the carriage to resist movement in either of the first direction and the second direction.
