A variable resistance exercise device is provided that comprises a pair of arm bands and a handle tube that has a longitudinal interior bore. The tube has first and second ends and includes a solid metal center shaft fitted through the interior bore thereby exposing respective first and second end portions of the shaft at the respective first and second ends of the tube. The first and second band arm of the pair of bands arms are respectively fitted onto the first and second ends of the shaft. In some instances, the device is part of a kit that includes a base having a bottom face, where the bottom face includes a groove, and one or more elastic bands, each such band configured to removably couple the base to the exercise bar by fitting the into the groove of the base and through the first and second arm bands.

In one example, a muscle exercise device includes a first arm, a second arm rotatably connected to the first arm, and the second arm and first arm configured to cooperatively define a recess. The muscle exercise device also includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm, and a wireless transmitter disposed in either the first arm or the second arm, wherein the wireless transmitter is responsive to communications from an app residing on a user device.

Hand held weight units of light weight manufactured as a solid unit, a shell unit with core insert combinations or modular units with interlocking ends. Shell units with core inserts and modular interlocking units allow for the changing of held weight by inserting or removing inserts or by locking or unlocking of modular weight unit sets creating varying held weight. The weight units are primarily used with upper body exercises during aerobic exercises in the home, outdoors, or in a gym setting such as walking or running to vary the intensity of workout during use.

The Hand Strengthener is a unique handheld exercise device that has manifold applications. The Hand Strengthener's design and utility is distinctive in several manners: Due to the device's non-uniform, contoured shape, the position and angle the user holds the device can strengthen and stretch different muscle and anatomy groups. The design's sphere shape fits in the users' palm for a comfortable, yet challenging handgrip on one side, while the two other contours allow for a uniquely different exercise experience for the users. Furthermore, the polyurethane material combined with the varied, and non-uniform shape allow for a therapeutic experience for the users. Our disclosures for research of competing devices clearly indicate a lack of multi purpose handheld devices with the Hand Strengthener's distinctive design, shape and contour.

An exercise machine tension device securing system for safely and efficiently securing selectable biasing members to an exercise machine. The exercise machine tension device securing system generally includes an exercise machine including a frame and a carriage movably positioned on the frame. A plurality of tension devices may be connected to the frame at one end; with the other end being removably connected to the carriage by a selection device. The selection device may include a plurality of slots for removably receiving one or more of the tension devices to secure the tension devices selectively to the carriage. A securing member movably connected to the selection device includes projections adapted to selectively enclose the slots so as to secure the tension devices within the slots of the selection device.

A resistance exercise apparatus enabling multiple concurrent workout/exercise movements includes a pair of handles adapted to be gripped by the hands of a user, a pair of first couplers connected to the pair of handles, a second coupler, a pair of ankle bands being adjustable to grip lower legs of the user above the ankles, and a plurality of elastic cords made of flexible and stretchable material. Selected ones of the plurality of elastic cords connect to and extend between the pair of first couplers and the second coupler and also connect to and extend between the second coupler and the pair of ankle bands.

Using a combination of jump rope, resistance band and boxing fitness instruments, one can get a robust anaerobic and aerobic exercise experience. However, traditional jump rope equipment requires the operator to be in a location that has ample height and space around them to accommodate the range of the rope being swung around the body. In addition, the ground surface that a traditional jump rope would be hitting may not always be ideal such as carpet, sand, and the like which diminishes the rhythm of the workout. The single unit multi-purpose jump fitness, boxing training and resistance strength device described herein eliminates the need for most of these restrictive considerations as there is no “rope” to jump over when in jump rope workout mode. Rather, the operator swings two specialized end handle units in a “jump rope” fashion while holding adjustable jump handles.

In one example, a muscle exercise device includes a first arm and a second arm rotatably connected to the first arm, and the second arm and the first arm are configured to cooperatively define a recess having a shape that changes as one of the first arm and the second arm moves toward, or away from, the other of the first arm and the second arm. The muscle exercise device further includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm so as to assume a configuration similar to the shape of the recess. Finally, a wireless transmitter chip is disposed in either the first arm or the second arm, and the wireless transmitter chip is responsive to communications from an app residing on a user device.
