A dumbbell has a left weight, a right weight, and an arched handle connected to the tops of the weights. In preferred embodiments, the bottoms of the weights are flat, the weights are at least as wide as they are tall, and the weights are parallel to each other. This configuration combines the advantages of a dumbbell and a kettlebell. The arched handle enables kettlebell-like arm raises, while the dumbbell configuration keeps the weights from pressing into the wrist. The arched handle also enables stable placement of the dumbbell over legs, knees, elbows, and ankles.

Systems and methods for a small light weight unit that can be securely held and centered in the palm of the holder during physical activities, such as exercises, including aerobic exercises. The weight unit also includes features for securing the weight in the palm during the exercise to achieve a specific desired weight and intensity of workout.

A core training apparatus for the golf swing. A semicircular member is coupled with a support member, and a resistance member is connected to one of the coupling points. The resistance member is secured to a fixed point, and the user rotates the apparatus back and forth with the user standing at the center rotational axis of the semicircular member, with the resistance member being guided along the semicircular member. The back-and-forth rotation acts to increase and decrease tension on the resistance member thereby exercising the core of the user.

An exercise support structure includes a knee support having a tiered recess with a bottom wall, a lower circular tier, and an upper egg-shaped tier; and a wrist support having a tiered support structure with a bottom wall, a lower egg-shaped tier and an upper circular tier, where the knee support and the wrist support are complementary in shape and are interfittingly received in mated relation to form a block.The edges of the tiers may be beveled, forming a smooth transition therebetween.The structure may be made from a soft, durable resilient material, such as foam, silicone gel, rubber, synthetic rubber, or organic tree sap.

Training apparatuses configured to receive, and conform to, the back of a user's knee and provide varying resistance and tactile feedback to a user performing quadriceps exercises and methods for using such apparatuses are disclosed herein. A preferred embodiment of the training apparatuses for quad sets comprises a solid, deformable, resilient body that includes a non-skid base and a top surface with a recess configured to receive the back of a user's knee. The body of this embodiment is preferably made of open-cell polyurethane foam with a uniform density ranging between 1 lb/ft.sup.3 and 8 lbs/ft.sup.3, and more preferably between 1.5 lbs/ft.sup.3 and 4.5 lbs/ft.sup.3. The embodiment provides gradually increasing resistance to compression, e.g. tactile feedback to the user's knee, when the user increasingly pushes his/her knee down against the embodiment, and thus allows dynamic quad setting and strengthening.

A rowing machine has a base, a seat, a rotating plate, two oar components, a damping mechanism and a transmission mechanism; the base with a rack and a slope rail; the seat cushion slidably coupled to the rail; the rotating plate with a fixing rotating shaft rotatably assembled to the rack through the rotating shaft; two oar components respectively connected to the two ends of the rotating shaft by unilateral bearings in universal joining way to unilaterally drive the rotating plate to rotate when swinging; the rotation damping mechanism is assembled to the rack; the transmission mechanism assembled between the rotating plate and the damping mechanism to drive a damping wheel of the damping mechanism when the rotating plate rotates.

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.

There is provided an orthotic configured for muscle imbalance correction. The orthotic has a strapping configured for physically activating an undercompensating muscle group by physically pulling substantially in-line with muscle fibres of the undercompensating muscle group to assist muscle activation and physically deactivating an overcompensating muscle group by physically pulling and therefore compressing across muscle fibres of the overcompensating muscle group to provide muscle resistance. Examples of the undercompensating muscle group are at least one of the gluteus maximus, medius, and minimus, vastus medialis and vastus medialis oblique. Examples of the overcompensating muscle group are at least one of the tensor fascia latae and iliopsoas.

An exercise device for the inner and outer thighs is discloses that includes a first arm and a second arm that extend from a central rod to allow for pivotal movement about the rod, wherein the first arm and said second arm further include a first and second plates and the plates are positioned on the proximal end of the arms, a resistance element is positioned between the first and second plates, and the arms further include a leg engagement elements on the distal ends of the arms, which provide lateral surfaces on opposite sides that are adapted to be engaged by both inner and outer sides of a human leg and, the device includes a movable flange member attached to the rod that is adapted to impose a variable axial force driving the second plate towards the first plate and compressing the resistance element, thereby creating a resistance to the rotation of said arms with respect to one another.
