While smaller in size (50 cm/22 inches) the BOSU Sport 50cm provides the same satisfying benefits as using the original BOSU Balance Trainer. You can use dome side up or dome side down for sports conditioning, HIIT circuits, strength training, general fitness, and yoga. Use one or more trainers to create a dynamic, flexible workout that isn’t only highly effective but fun.


Travel Size (50 cm/22 inches)

The BOSU Sport Balance Trainers’ small and compact size makes it travel-friendly. Weighing just 10 pounds, 22 inches across with recessed handles, it’s easy to carry around, store, and save space.

One Trainer, Two Types of Training

You can use it dome-side-up almost like a step: Stand on it, sit on it, lie down on it or bounce around on it for cardio, lower body strength, or core moves. You can also turn it over and use the platform side for upper body exercises, like push-ups, or more core moves, like planks. It’s essentially having two different pieces of equipment in one!



It features 6 rubberized non-skid feet, and it’s non-marking, so you can focus on your form without worrying about a fall.

burst resistant

Extreme Durability

Phthalate and latex-free with burst-resistant material, the BOSU Sport Balance Trainer can support up to 250 lbs. It’s extremely durable and long-lasting.

Results for any fitness goal

Great for full-body workouts that strengthen and tone while improving balance, agility and flexibility.

Buyer’s Guide

Why you should bring Accessories & Conditioning Equipment home?

  • Accessories & Conditioning includes a broad range of tools to help you optimize training at home and on the go
  • It includes monitoring tools, resistance (for strength and balance), mobility, stability, rehabilitation, training-specific tools (yoga, floor exercise, MMA, Boxing, etc)
  • The options are limitless. It can be hard to know what you need without some guidance. And we might have an accessory that you haven’t heard of to help you with a goal or challenge! Ask in the chat or visit a store if you aren’t sure.
  • Warning: this category is susceptible to fads that don’t work. Don’t worry, you won’t find those at Fitness Town. All of our products are reviewed by our expert team which includes trainers, kinesiologists, and diverse training and sport backgrounds.
  • Another warning: there are a lot of poor-quality accessories online. If it’s cheap… It’s cheap. We carry a mid- to high-quality range. If you’re a casual user, our lower cost items will probably be all you need but choose the higher cost items if you use them regularly in your household. This will help us all reduce the amount of fitness accessories in our landfill.
  • To help you select the appropriate accessories for you, we’ve categorized them common needs, interests, and uses.
