CROSS-REFERENCE TO RELATED APPLICATION

[0001] The present application claims priority to, and the benefit of, U.S. Provisional Application No. 63 / 757,862, which was filed on Feb. 13, 2025, and is incorporated herein by reference in its entirety.FIELD OF THE INVENTION

[0002] The present invention relates generally to the field of fitness equipment. More specifically, the present invention relates to a weight-attachable water bottle and a thermal belt assembly. Accordingly, the present disclosure makes specific reference thereto. Nonetheless, it is to be appreciated that aspects of the present invention are also equally applicable to other like applications, devices, and methods of manufacture.BACKGROUND

[0003] Walkers and joggers often encounter challenges related to simultaneously achieving hydration and resistance training during their workouts. The use of separate equipment such as handheld water bottles and external weights introduces logistical difficulties, requiring users to manage multiple items that may be awkward or cumbersome during physical activity. Traditional water-filled weights diminish in mass as the liquid is consumed, leading to fluctuating resistance and inconsistent workout results. Wrist weights, while offering a hands-free alternative, may absorb sweat during use, resulting in discomfort or skin irritation, and in some cases exacerbate pre-existing wrist injuries. These limitations reduce the overall effectiveness and appeal of integrating strength training into cardiovascular exercise routines. Users seeking comprehensive fitness solutions are thus forced to make trade-offs, often compromising hydration for resistance or vice versa. As a result, the fragmentation of hydration and resistance tools undermines exercise efficiency, impedes convenience, and may deter individuals from adhering to consistent training programs.

[0004] Therefore, there exists a long-felt need in the art for a weight-attachable water bottle and belt system that enables simultaneous hydration and resistance training without requiring multiple separate pieces of equipment. There also exists a long-felt need in the art for a weight-attachable water bottle and belt system that maintains consistent resistance through customizable weight modules as water is consumed. Moreover, there exists a long-felt need in the art for a weight-attachable water bottle and belt system that incorporates storage and thermal stimulation features to enhance workout efficiency and user comfort.

[0005] The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a weight-attachable water bottle and belt system. The system is comprised of a weight-attachable water bottle and belt system comprising a water bottle and a thermal belt assembly. The body of the bottle comprises top and bottom edges equipped with external fasteners configured to engage corresponding reciprocating fasteners on attachable weight modules. Each weight module is configured to reversibly attach to either end of the bottle and to serially couple with adjacent modules via secondary fasteners, thereby allowing modular stacking for adjustable resistance. Weight modules are provided in varying masses and may include features such as straw holes for hydration access. The belt assembly comprises a thermally active belt body constructed from insulating materials and is configured to be secured around the user's torso, waist, or hips using adjustable fastening mechanisms. The belt body comprises a plurality of pockets and holsters dimensioned to hold the water bottle, weight modules, and accessories, each secured by closure mechanisms to retain items during movement. A method of use is also disclosed, comprising steps of selecting and attaching weight modules to the body, inserting a straw through aligned modules and into the body, securing the belt, and performing physical activity while carrying or wearing the integrated system to enable concurrent hydration, resistance training, and thermal stimulation.

[0006] In this manner, the weight-attachable water bottle and belt system of the present invention accomplishes all the foregoing objectives and provides a system that integrates hydration and resistance training into a single device, thereby eliminating the need for separate exercise implements. The modular attachment of weight modules enables consistent resistance even as water volume decreases, thereby addressing the issue of diminishing workout intensity. The inclusion of thermally active materials and secure storage features in the belt further enhances workout efficiency, comfort, and convenience, supporting both hydration and fat-burning goals.
