5 Greatest BOSU Balls and Stability Trainers in 2025

Ask a physical therapist how you can subtly level up your workouts, and they’ll probably recommend trying the best BOSU balls (and other types of balance trainers). If you’re unfamiliar, BOSU stands for “both sides utilized,” in a nod to the way the brand’s gear engages your whole body. A BOSU ball is an inflatable, burst-resistant dome that looks like half of an exercise ball that sits on a thick plastic base. It’s been a gym equipment staple for the last 20 years and has inspired countless lookalikes.

“A BOSU ball instantly turns almost any exercise into a stability challenge,” Hayley Akradi, CPT, a certified personal trainer at Life Time and the creator of the Body Blueprint Program (launching soon on the free Life Time app), tells SELF. “You’re not just working muscles, you’re training your neuromuscular system. The unstable surface forces your body to react and adjust in real time.”

Curious what this versatile tool can do for your home workouts? You came to the right place. Below, we highlighted the best models you can try (including expert-approved options from BOSU as well as some budget-friendly dupes) and got the low down on their benefits from Akradi.

Best Overall: BOSU NexGen Home Balance Trainer

Bosu

NexGen Home Balance Trainer

Two judges for the 2023 SELF Home Fitness Awards shouted out this BOSU model, noting its durability and overall performance for a variety of workouts (everything from strength training to yoga). The textured surface of the ball makes it easy to grip, while the rubber feet on the base keep the whole thing steady.

The NexGen is great for seasoned users, but it’s beginner-friendly too: It comes with downloadable workouts and a wall chart, for plenty of exercise inspo.

Best Splurge: BOSU Pro Balance Trainer

The high-quality BOSU Pro is a longtime favorite of Akradi’s. “It’s durable, grips the floor well, and can handle everything from slow stability drills to max-effort plyometric training,” she says. “The commercial-grade texture also makes it more comfortable for hands, knees, and forearms during bodyweight work.”
