An electronic punching bag includes an elongate bag formed of resilient material, a microprocessor disposed in an interior of the electronic punching bag or at a periphery of the electronic punching bag, and a display screen that extends around more than half of the periphery of the electronic punching bag. The display screen is configured to receive signals from the microprocessor. The signals cause the display screen to display visual signals.

A training device for monitoring a physical exercise is formed having a volume element, a sensor apparatus which is designed to detect a mechanical force and/or a pressure which a user exerts on the volume element while performing the physical exercise, and to generate a measurement signal on the basis of the detected force and/or the detected pressure, and an evaluation apparatus which is designed to compare the measurement signal generated by the sensor apparatus with a value range and/or a target value and to automatically generate an output signal on the basis of the result of the comparison.

A ground based launching assembly for feeding balls vertically upwards to a user. The user may takes strokes at fed balls, thereby delivering the balls towards a catching assembly. The catching assembly receives the balls and gently returns the ball back to the launching assembly. Disposed between the catching assembly and the launching assembly is a return ramp and a ball sequencer. These require no more than ten feet in length. Such a device may be readily used in a single car garage or other small room.

Versatile exercise apparatus is portable and provides adjustable volume to weight ratio for multi-purpose weight, cardio, sport-specific, and martial arts training. Versatile exercise apparatus provides a user with the ability to adjust volume to weight ratio using a waterproof fillable cavity. The different markings on the transparent viewing window of the apparatus allow a user to vary the difficulty level of workouts by changing the corresponding weight of either water or sand added to the apparatus. Versatility is provided by the apparatus either being used as a backpack or a hand-held free weight, or a punching bag.

A system is provided by applying pressure to a portion of a body of an individual in a chamber having an aperture along a vertical axis for receiving the portion of the body of the individual. A pressure sensor is coupled to the chamber for measuring a pressure inside the chamber. A negative feedback control system, calibrates, adjusts and maintains the pressure inside the chamber.

To provide a training apparatus for effective and safe performance of KAATSU training. A training apparatus is made up of a tight fitting band 100, a main device 200, a measuring segment 300, and a control segment 400. The tight fitting band 100 is wrapped around a predetermined region of a limb. The tight fitting band 100 has an air-tight inflatable bag. The compression force applied to the limb can be varied by supplying the air to and removing the air from the inflatable bag. The main device 200 controls the supply and removal of the air into and from the inflatable bag. The measuring segment 300 is attached to the limb around which the tight fitting band 100 is wrapped to measure the magnitude of a pulse wave. The control segment 400 determines, in preprocessing performed before the KAATSU training, the pulse wave component at a time point at which the magnitude of the pulse wave reaches the maximum, and chooses, as an appropriate gas pressure, the pressure within the inflatable bag that is produced at a time point at which such a pulse wave is generated that is obtained by means of multiplying the pulse wave component at a time point at which the magnitude of the pulse wave reaches the maximum with a numeral equal to or larger than 0.2 but smaller than 1.

A fitness training aid including a flexible, impermeable membrane defining a chamber fillable at least in part with a first flowable material and at least in part with a second flowable material, at least closure coupled to the membrane, at least one gripping member coupled to the membrane, and at least one wall positioned within the chamber. The closure positionable between at least one open position enabling the first and/or second flowable materials to be introduced within the chamber, and a closed position that seals the first and/or second flowable materials within the chamber. The at least one wall and the membrane define at least first and second compartments within the membrane. The at least one wall enables fluid communication of the first and/or second flowable materials between the first and second compartments.

A core strengthening device includes a tray and a ball. The tray has first and second opposing sides. The first side of the tray has a recess formed therein. A ball is selectively positionable at least partially within the recess in the tray. The ball has a first hemisphere and a second hemisphere. The first hemisphere has a first radius and the second hemisphere has a second radius that is different than the first radius. The core strengthening device provides instability to exercises, which requires a user's core muscles to work harder to perform the exercises and maintain balance, which strengthens the user's core muscles.

An exercise balance board may have at least a platform for a user supported by a resilient, air-filled partial sphere. It contains features which allow users of any size or fitness level to properly exercise muscle groups. The balance board allows a user to exercise upper and lower muscle extremity groups either individually or simultaneously.

The various devices and systems herein include oropharyngeal exercise devices having a pump bulb with a bulb body having a flow restriction structure with a restricted configuration in which the flow restriction structure is configured to restrict the flow of fluid through the lumen such that the user must apply a force to increase the flow of the fluid. Other devices include containers and/or lids thereof with the bulbs attached to or integrated therein.
