About Us

What is BOSU®?

*Pronounced “Bo,” like the boy’s name, and “Sue,” like the girl’s name.



What began as the launch of one of the most innovative products the fitness industry has ever seen, turned out to be just the start of a journey that continues to expand, shape and define functional training.



Invented by David Weck, the BOSU® Balance Trainer debuted in 2000 and quickly became one of the most successful fitness training products in the world. Originally, the name “BOSU” was an acronym for “Both Sides Up.” It meant that the BOSU® Balance Trainer could be used on either side, the dome or the platform.

Today, the term “BOSU” has evolved beyond the product to now mean “Both Sides Utilized,” a mindful approach to exercise that is a step beyond traditional training. This clarity of who we are and what we want to offer inspired the development of additional BOSU® products and programming, all of which are grounded in exercise science and proven in real-life application.



BOSU® Training is about expanding movement capabilities, reshaping bodies and strengthening minds. It’s about inserting thought into movement. It’s about asking our clients, fitness students and athletes to be physically involved, but to also be present and fully engaged in the training process.



It doesn’t matter if you’re facing the toughest competition of your athletic career, looking to return to a fitter you, or just starting out. BOSU® Training can see you through it all with new challenges and exercise progressions always just around the corner.



Not Just the Product



Our products are known industry-wide for training balance, enhancing flexibility and delivering killer cardio workouts. They have an unprecedented reputation for building strength and fine tuning skills for sport.



But on their own, BOSU® products are just molded plastic, weighted rubber, and stability balls with secret filling. You have to engage them in order to bring them to life! So, beyond our products, we offer a system of mindful action, intentional movement and smart science that produces results.



The BOSU® training approach makes certain that when you get on the BOSU® Balance Trainer, or move with the BOSU® Ballast® Ball, you get everything you ever wanted from a feel-good, get-fit, no-regrets training tool. Even more than that, you get an intelligent training method that transcends any piece of fitness equipment.

Made in USA



Like many industries eager to cut costs and boost profit margins, fitness equipment companies are shipping production and jobs overseas. But at Hedstrom Fitness, we are committed to supporting U.S.-based manufacturing and the sustainability of our country’s valuable human resources. BOSU® products are made right here in Ashland, Ohio, adjacent to our corporate headquarters. So, not only do we have state-of-the-art manufacturing facilities and competitive pricing, but we actually know the people involved in the process.



Green, Environmentally Conscious Manufacturing



We make products intended to promote health, wellness and an overall better quality of life. So, it only makes sense that how our products are made is as important to us as how they are used once in your hands. Even before it was fashionable, Hedstrom Fitness has been committed to the use of renewable resources, recycling and the elimination of toxins that harm the environment.
