Nationwide (USANews.com) Jolt Bar LLC, a Chicago-based startup, has launched an innovative palm cooling device designed to complement athletic performance by supporting strength, endurance, and recovery through a simple and user-friendly mechanism. Developed and manufactured entirely in the midwestern United States, the Jolt Bar uses temperature-responsive technology in a compact, portable design, making it a practical tool for both fitness enthusiasts and athletes.The concept of palm cooling has been steadily gaining interest in sports science, with discussions appearing in platforms like the Huberman Lab podcast. These conversations have explored the benefits of targeted cooling during exercise, such as enhanced physical recovery and performance. Drawing from these insights, Jolt Bar offers a commercially accessible product that allows users to fill the device with cold water and hold it during rest periods in their workouts. Since the palms are rich in blood vessels and play a role in thermoregulation, cooling them has been proven to help optimize recovery and delay fatigue during intense exercise.

Priced at just $59, it offers a more accessible alternative to other palm cooling technologies on the market, many of which cost over 900 dollars and are often bulkier or designed for institutional use. Jolt Bar, about the size of a standard water bottle, is easy to carry to the gym, on hikes, or to competitions.A distinctive feature of the device is its proprietary color-changing element, which signals when the device has reached an effective cooling temperature. This intuitive indicator helps users integrate the device seamlessly into their routines without guesswork.Results from a scientific study over a six-week trial period have shown promising outcomes, with participants reporting significant improvements in training endurance, repetition volume, and strength performance. On average, users more than doubled the number of pull-ups they could complete. While individual results may vary, these findings highlight the potential of cooling strategies to support physical performance by regulating core body temperature and reducing perceived exertion.“Many people turn to supplements or stimulants to boost their performance, but thermal regulation offers a natural and often overlooked advantage,” said a spokesperson from Jolt Bar LLC. “With Jolt Bar, we aimed to create a reliable, easy-to-use tool that brings science-informed performance support and professionals alike.”The product’s development was driven by a mission to democratize access to performance-enhancing tools previously limited to elite training facilities. Jolt Bar’s U.S.-based design and manufacturing approach also ensures quality control and supports domestic production.Unlike bulkier devices used primarily in lab settings or athletic institutions, Jolt Bar is designed with individual users in mind. Its compact form fits easily in gym bags, lockers, or travel gear, making it ideal for personal use across a variety of workout environments.While the fitness industry continues overcomplicating solutions like wearables and AI-driven tools, Jolt Bar offers a back-to-basics approach. Requiring no batteries or apps, it leverages a fundamental physiological principle with practical benefits.Looking forward, Jolt Bar LLC plans to expand its product line to include complementary devices tailored for various physical activities—all while maintaining a focus on affordability and user-friendly design. The current model has already garnered attention from fitness professionals and recreational athletes alike.Stay tuned this summer for jolt bar sponsored events, exclusive offers and promotions.
