BOSU SPORT IS GREAT FOR KIDS AND SMALLER ADULTS

The smaller size and fun colors of the BOSU Sport makes it a great way to get kids exercising in an energetic and fun way. When kids jump, bounce and balance on the BOSU Sport they’re getting a cardio workout, building strong bones and strengthening their bodies. The BOSU Sport is also a smart choice for smaller adults.

Does Everything a Full Size Balance Trainer Does

The BOSU Sport Balance Trainer may be small, but that doesn't mean it can't do everything a full-size balance trainer can. Perform all the same exercises on the BOSU Sport as you would on any BOSU Balance Trainer.

Was so excited..until…but much better now.

Was so excited..until…but much better now.
Just got my Bosu and was so excited, until I turned it around and saw one of the legs is missing. :( C'mon...there should be better quality control on this product. Requested a replacement. Will update after I get replacement...but I am very disappointed.Update…So, I got my replacement the very next day! And it was fine.I compared the packing from the replacement with the first one and it was different, much more secure with the replacement. I honestly think that the first one they sent to me was a return from someone else and they didn’t bother to fix it.In any case. I am very happy - so far - with the replacement. But for the money we pay for this, I would have love to have gotten written hard copy of instructions AND the plug removal tool. Seriously… And, yes…inflating it was NOT easy…easier to use the BOSU than to inflate it.

    UPDATE: 11/27/15 - The small diameter is not ideal for Pilates. I would recommend the largest for pilates on the Bosu. This small Bosu is better for vertical workouts or very petite individuals. ....Original Review: This is a nice quality Bosu. Works really well for my Intensity Workout and is easy to store and protect from my cats by simply draping my yoga mat over it when not in use. I do, however, need to use a folded up yoga/sticky mat underneat, as it can slide when doing front lunges on a carpet. No fault of the Bosu, just something I learned with certain moves. The sticky mat keeps it nice and secure and safe. The Bosu is very very challenging and takes a few weeks to master in terms of safety and being able to execute moves. My balance has increased to a degree I've never achieved before and I'm pretty stoked about that. I'm also able to do my entire intensity workouts, every move, after only two weeks of being a newbie. This is a smaller Bosu, so if you are tall or have a wide stance, you may want to buy the larger Bosu. I'm 5'6" and struggled a bit with it at first but realized it was because I was so bad at it. Hahah. I'm now able to balance on it and feel its' a good size for me.

    I recently bought this BOSU Ball from Amazon to make it an integral part of my workouts. I am currently doing PT for leg strength and flexibility and I think this BOSU ball will really help. My PT guy uses it when I go to see him and I want to do it more often. I think it also really helps with balance issues.

    Received Jan 2025 and noticed by mid Feb 2025 it does not hold air / slow leak. Only use for 10 min per day and have to pump it up each time. Pumped to firm level and by next day needs more air. I bought the same brand our PT has and am very disappointed with the quality. Return window was end of Jan and there is no way to even contact the company. For $80 this is ridiculous.

    I'm 5'2", petite build, narrow shoulders
    The 50 cm model is EXACTLY what my workout needed! I've long used the original Bosu at the gym but found them cumbersome for exercises with the Bosu in my hands. The 50 cm smaller size helps me achieve better form, is easier to maneuver, and I even love the blue / lime colour combo! All the same materials, high quality, and function of the original. Easy set up - was using it within 5 min of opening the box. Highly recommend!
