An ankle exerciser for exercising a user's ankles and includes a base, two pedals and two rotary units. The pedals and the rotary units are installed to the base. The rotary units are located between the base and the pedals so as to allow the pedals to be pivoted in multiple directions so as to stretch the ankles, and to keep ankles healthy.

An athletic mouthguard with lung exercising variable, two-way airflow-restricting valve is disclosed. The mouthguard has a mouthpiece with a lower tooth bed and an upper tooth bed overlying the lower. Outer and an inner sidewall connects the beds. A channel passes between the lower and upper beds with a first end open within the inner sidewall and a second end open within the outer sidewall. Certain embodiments include a channel wall which separates the channel into multiple channels. A manifold in fluid communication with the channel terminates to a centralized aperture with a valve seat. A rotatable valve member in the valve seat has an aperture therethrough.

Embodiments of an exercise device for squat training are disclosed. The exercise device disclosed herein provides users with a stable lower extremity base to help assure good motor function of the squat exercise to improve efficient flexibility, coordination, strength, and endurance development.

A support device for a bicycle includes a support structure, a fixing group supported on the support structure and also includes a movable element and a retention element configured to hold the front fork of the bicycle. The support device also includes a lifting/lowering device of the fixing group, in which the retention element is integral in translation with the movable element. The support device further includes connection means configured for slidingly fixing said fixing group to the support structure in such a way as to allow displacements of the fixing group with respect to the support structure along a compensation direction transverse to the vertical direction.

A support device for a bicycle includes a support structure, a fixing group supported on the support structure and a movable element and a retention element configured to retain the front fork of the bicycle. The support device further includes a raising/lowering device of the fixing group, the retention element is translatable jointly with the movable element, and the retention element is rotatably connected to the movable element.

A resistance exercise apparatus includes a support formation or platform for supporting the bodyweight of a user. The apparatus includes a pulley system with pulleys around which a cable is threaded, as well as a resistance mechanism with a pneumatic actuator connected to the pulley system. The cable has a handle on which the user can exert a muscular load so that the muscular load is transferred by the cable as a tensile load, to the resistance mechanism and the resistance mechanism being configured such that the pneumatic actuator exerts a resistive force against said tensile load.

A mechanical braking system which can provide a brake to a self-powered treadmill, or a dual mode treadmill that can operate in both self-powered and motor-powered modes, that will rapidly halt the motion of the belt or rollers in the event of a power disconnect such as from the removal of a safety key.

Devices such as medical devices, including those for use in conducting pelvic muscle exercise, are generally provided. Embodiments herein relate generally to the medical device and consumer medical product fields, and in some embodiments, to a device for sensing, guiding, and/or tracking pelvic muscle exercise in men and women for the purpose of treating urinary incontinence, sexual dysfunction, and other pelvic conditions.

An exercise machine support system for providing increased versatility including inclination or declination of an exercise surface, a reduction in the overall length and width of the exercise machine, and an enhanced user interface which reduces the risk of injury. The exercise machine support system generally includes a cantilevered exercise machine which is adapted to have a variable angle of incline or decline with respect to a horizontal ground surface. The exercise machine will generally include a base and a support which extends between the base and the exercise machine. The upper end of the support is connected to the exercise machine by a first pivot such that the exercise machine pivots about the support. An adjustment device may be utilized to pivot the exercise machine and thus adjust its angle of incline. Various types of adjustment devices are disclosed, including an actuator, ratchet-and-pawl, gears, and cam.

Provided is a chest expander including a pair of operational arms having upper ends rotatably coupled to a head and moving to approach or be spaced apart from each other and a pair of gas springs disposed crosswise between the pair of operational arms. In the operational arm, a longitudinal hole configured to guide one end of the gas spring to move are formed. A guide coupled to the one end of the gas spring are arranged in the longitudinal holes. A Holding device holds the guide at a selected position. Intensity of elastic force provided by the gas spring is adjustable by adjusting a position of the one end of the gas spring.
