Bosu pro balance trainer

Had knee replacement and use while at physical therapy. At therapy their ball clearly states Bosu Pro mine doesn’t have pro listed anywhere. Hmmm

BOSU ball - 1. Me - 0

So I went with the Pro Version, "Used - Like New" and saved me a little cash....got the price down to close to what the home version would have cost. Came in perfect condition. I "had" to get the red and black because those are my home gym colors. Hahah...home gym nerrrrrrd alert...:-P I've used BOSU balls before...but this Pro version feels heavy and the ball portion feels thick AF. I considered the new NexGen style...but the reviews were a little hit and miss...probably because it's a newer version and maybe all the kinks haven't been worked out. This Pro version has been around for a long time....plus the new NexGen didn't come in red or black...hahaha.I used it this morning for wide grip pushups ball side down and close grip pushups ball side up.....and it kicked my butt. I can do(ish) regular pushups...but I like the extra instability to work all the little shoulder and so forth stablelizer muscles.I thought it would be heavy and nice....but it's even heavier and nicer tbh....and a great and super sexxxy addition to my home gym.Can't wait to keep using it to get to know suffering....:-)

Good for sensory needs for my teenage son

This is my second Bosu Ball and I use it but what I found is that my son with severe autism uses it to jump on for sensory needs. Now that he is 16 years old he destroys all sizes of trampolines cuz he is too big and hard on them but the Bosu Ball has held up a long time and I like that you can reinflate it when it goes down

Great workout tool

It is standard on all gyms there are a bunch in the group fitness room for classes there are some in both the upstairs and the downstairs weight rooms.

The provided Air pump would not inflate the BOSU to the specified hight

This is an excellent product and well made. Unfortunately the provided pump used to inflate the BOSU would not hold the pressure needed to inflate it to the 8.5” required fight. There was too much air leakage around the piston shaft. I got a better pump and it worked fine.

Very effective

Wife has vestibular hypofunction. This balance trainer has allowed her to include specific physical therapy exercises into daily exercises at home and reduce PT visits. Paid for itself fast. Very durable. Easy to inflate.

Love it

It works exactly as it should. I know they have various versions of the Bosu and I've used a couple of them. This version is great. I like that it's black so you don't see the scuffs as easily as you do with the blue versions.

Poor quality control, awful company

Product might be decent but who cares if that's the case if it constantly loses air. It deflates overnight every time. It's an expensive trainer but the company can't figure out a 5 cent plug to work properly. I literally have to hold the plug at a certain angle or it will automatically lose air. The only work out I got from it so far is my arms as I have to inflate the thing on daily basis.UPDATE: The company had the audacity to charge me 50% restocking fee on a faulty item! After paying $174, I received a refund of $87 due to "condition of the item." Absolutely ridiculous that an item I "tried" to use for 2 days and is brand new was flagged. They will not even explain the precise reason for this. The seller is trying to tell me that I am only getting a $87.09 refund on an item I paid $174.19 with the explanation that restocking fee applies due to the condition of the returned item. There is zero explanation on what that condition is. I returned the item properly and it looks exactly how I received it. Spreetail company, if you are wondering where all the items are (two plastic plugs), they are INSIDE your ball. The ball itself was defective and kept deflating so to keep the air in, plugs where pushed slightly too far and went inside the ball. 50% restocking fee on a damaged item should be criminal.

Lower back pain… just gone

I’m in literal disbelief.I’m 45 and fairly out of shape. My lower back just stays hurting. I get out of bed and immediately reach for the wall. Getting up from sitting is always accompanied by lower back pain and groaning and trying to balance my upper body so I don’t topple over from pain.I got this thing and some adjustable weights. Looked at them for a couple of weeks. Tucked under the tv. I’ve wasted money on exercise equipment and gym memberships before, so no big deal.Well about 8 hours ago I set the dumbbells to 5lbs, popped my shoes and socks off, put a 20 minute standing dumbbell workout on YouTube and literally just went through the motions. Nothing serious, but I did feel a lot of stuff going on all over my body as I constantly had to stay balanced.About halfway through the workout, I had start stepping off the ball during the 20sec breaks between exercises (it was a 40sec on 20sec off type video) to give my legs a break.For the last 8hours I have felt nothing him my lower back. I’ve also noticed the absence of pain in other areas that I kinda just got used to. My left hip, especially.I mean I feel nothing. No pain.I wondering if it’ll be too good to be true come morning. But for less than 30 minutes of working out, I feel just so pain free.The ultimate test was standing up from an arm chair while holding my 40lb little boy and then raising him to the ceiling like he weighed 10 lbs.I don’t care if I don’t build an ounce of muscle. If the lower back pain stays away, that’s worth it for me!

Great customer service!

My initial opinion of this product was quite low. My attempts to inflate it were unsuccessful with the included pump. I tried for quite some time before enlisting the help of my husband. He gave up after also trying for longer than I thought he would. (I guess he really does love me!) After we both failed I reached out to the manufacturer directly and received a quick response. They believed that the pump was faulty and offered a replacement pump. I provided my mailing address and received the replacement in just a few days. Problem solved! My Bosu trainer is now inflated to the recommended 8.5”. Let the training begin!!

HAPPY - Working on my core for strength and balance!

My therapist recommended that I get my ball to sit on daily to gently and gradually strengthen my core and back muscles. In my research for a new ball, I stumbled across the Bosu. It turns out that this is a great item to add to my exercise tools. I have been struggling with not injuring myself when I try to exercise. I always injure myself doing the simplest of stretches or exercise moves. Then I have to stop my exercise plan to recover. I really want to build strength and flexibility as I am getting older. I have had a few health issues and I am limited on what I am able to do. I am so glad I found the Bosu. I am using the Bosu to strengthen my core and increase my stability and balance by standing on it and keeping myself from falling off the ball. It is challenging but not too hard and I do not feel that I have hurt myself or “over done” myself afterwards. I can feel it in my legs and my stomach as I maintain my position on the ball. Now, I don’t think I will ever be able to use the Bosu for the hard core exercise I see people do in the videos because of my physical limitations, but I see great potential in building muscle and strength.

Got my own

I'm still in denial about it, but I'm getting old and losing balance. I had never considered a "yoga" ball until I saw a lady doing a workout on a Bosu Ball at LA Fitness. I did not realize how bad my balance was until I attempted to copy some of her moves. Gravity sucks; it's a good thing I can still take some tumbles.My neighbor is a Super Bowl Ring-wearing former NFL and CFL coach with whom I share occasional walks and rides. I figured he'd be the right guy to ask about Bosu Balls for balance. Good call. He had a dusty, flat Bosu Ball sitting in his garage that he said I could use. It cleaned up nicely and became a part of my daily regimen. The Bosu Ball alone can provide a good workout; and, I can tell the difference in my balance. Helping to keep those neurons and muscles working.While working with the loaner Bosu Ball, my daughter had a baby. She started using the Bosu Ball as part of her recovery routine. I've also incorporated the Bosu Ball into my baby workout routine. Like, Bosu Ball Baby situps. Cradle the baby in your arms while you do your Bosu Ball situps. Baby loves it; wears out Grandpa. I think there's a training video in there somewhere; maybe we'll see you on YouTube ;).Meanwhile, my friend started to develop problems in his lower back and is trying to avoid surgery. I mentioned to him that the BOSU Ball provides good support for stretching my back; so, maybe it was time I return his Bosu Ball and buy my own. With a new purpose, he's a new convert to his old Bosu Ball.At home, my Bosu Ball Pro Balance Trainer arrived today, is pumped, and has already wore me out.A negative: Bosu charges for and passes the cost of printing and burning training materials to the customer. The Bosu Ball came with instructions on how to pump up the Bosu Ball. If you want training resources, you will have to register on the Bosu website, buy and download the training resources, and print or burn them yourself. I found a small crumpled piece of paper in the box that had a coupon code in 8 point type that I could use to download digital files for training DVDs, a 120-page training guide, and two wall posters. As much as I appreciate the digital downloads, I'm disappointed that the product comes with neither a printed training guide nor a training DVD. I paid a premium price for a premium product, and the company is passing the cost of printing and burning to me. For those who do not receive or cannot locate the coupon code buried in the box, Bosu charges $20 to $25 for each media item you want, and you'll still have to print and burn them on your own.Regardless of the disappointing follow-through, the product itself deserves five stars.

If you have used a BOSU for years like me, a no name brand will not make you happy.

If you are like me and are debating between a Bosu balance trainer that you have used at the gym for years and aren't going to the gym right now or a no name generic look alike balance trainer because it is cheaper and how can it be that much different, may I save you the work of a return and just really consider purchasing the Bosu Ball. They are very different. There is no comparison. The BOSU wins, hands down.My experience:I have used the BOSU pro balance trainer for a couple years at the gym. My main thing is building balance. Since I am not going to the gym right now, I wanted a balance ball trainer for home. I looked at the price of The Bosu ball and then the price of the no names. Some of the no names are over 1/2 of the price less than the Bosu. Many of them have great reviews. I chose one that around $85. It had great reviews. I received it. Set it up. Tried it out. I said a bad word because right out of the box freshly pumped with air, I could tell the difference just standing on it with my two feet. My feet were curving out with the curve of the ball. I tried letting air out. I tried refilling it. I measured it from the ground up to make sure I was filling correctly. It didn't matter, there was this new found pressure on the ankles, feet and low calves/shins.Standing on the BOSU trainer feels extremely different than the no name one. On the Bosu trainer, my feet don't curve out. When I stand on it, I feel with the BOSU I am able to correct my posture whereas the other one I was fighting to keep my ankles from turning out.The feel of the material is very different on the BOSU trainer vs. the no name. The no name felt very stiff under my feet. The no name felt like it had to be broken in before it could be effective. Kind of like a new pairs of shoes. The BOSU the material is strong and flexible. Feels good on the feet.Picking up the BOSU is easy. It is made to be easily picked up off the floor. The no name one was a struggle to move because you had to find the little metal piece that was about a finger length wide to pick up.The surface size makes a difference. The BOSU pro is over an 1 inch bigger in diameter. I didn't think this would make difference until I tried doing exercises on the no name brand. I couldn't find my grip and there just didn't seem to be enough surface area.All in all, when I received my BOSU trainer today, I took it out of the box. Filled it within minutes. (the no name took me forever. I thought there was a hole or it was broken.) Stood on it. The let out a big sigh of relief and satisfaction. Having used a BOSU ball for the last couple years, I now understand that there is not another balance trainer that would equate to it.

Very Solid

I previously bought one of the cheaper balance trainers and returned it (Scool trainer.... https://www.amazon.com/gp/product/B0855VG99M/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1)The Bosu is much better. Here's why:1) Rubber ball - this is close - Bosu is thicker, but not 100% clear how much that matters; the cheaper one seemed ok. I suppose over the long-term the thicker material will be better for retaining air. So Bosu wins here.2) Inflator - this was also a push - same idea, different execution. Neither of them were high quality - both seem like they could easily break, but it's not something you use all that much and both appear to use a fairly standard size inflation system.3) Base - this is where the Bosu is 100 x better. I use the Bosu on both sides. When the flat side is down, the entire base of the Bosu is on the floor, and it grips the ground very well (painted cement floor). The cheaper one used a few stick-on 1/8-1/4" "feet" that gripped well, but one of them came off in the first use - there is no way they would have stayed on for years. That was a pathetic design. Bosu wins hands down here4) Base - flat side up - this is the other place that Bosu blows away the cheaper one. The cheaper one had a textured hard plastic. It is pretty easy to slip on that (when standing on the flat side) despite the texture because the plastic material is not grippy at all. The entire base of the Bosu is made out of a material to which your shoes grip much better. Hands down winner for Bosu here5) Stretch bands - this is a push - the Bosu does not come with them whereas the cheaper one did. That said, the bands with the cheaper one were pathetic. Perhaps if you've done no arm work in decades they might be ok, but they simply don't have enough length in the stretch to be remotely helpful for most people I would think.The "Cheaper" one was still $90 with tax. I suppose if it was $35 I could justify the quality difference. But for the extra price the Bosu is worth it.

Great for stability training.

This thing is great. I have used them before with a Trainer at 24 H.our Fitness gyms here in Norther California. One of the clubs is in a college town and they really get used and abused there. I see some people jump pretty hard on them. When I decided to get one for myself I got the Pro Balance Trainer myself. Directions say fill it until it is 10 inches high, so I flipped it over, put a level on it and carefully filled it until the bottom of the level read inches. I used a really nice blow gun with my 30 gallon compressor, a mechanic has to have one. That seemed pretty darn full and solid, not enough bounce for my liking so I lowered it down to approx. 9.25" to 9.50". I have felt and used them much squishier than that at they gym and they hold up fine from what I have seen. I would recommend this and buy from this company again.But I wish I could buy an original BOSU REPLACEMENT PLUG! The original BOSU plug has a big ridge on the tip you insert in first, it locks it into place. I did purchase other aftermarket Stability/ Balance Ball replacement plugs at the same time but they are not the same. They are shaped just like a straight plug that gets pressed in, no swollen locking fat part on the tip that locks it into place. I don't need it now but I like to be prepared. The unit would be absolutely unusable without the ability to hold air. Does anybody know where to get an Original BOSU Replacement Plug? Seller... hint...hint...

Best piece of equipment I purchased to fight the middle age spread!

Tired of just doing step aerobics, I thought of using the Bosu ball as an addition to my routine. I admit I had hesitation about purchasing it because of the negative issues with the pump. I had used it at the gym, and thanks to it and cutting out sodas, I lost fifteen pounds and inches thanjs to the Bosu ball. I sweated a lot, and really had to focus on balance. All this, I feel contributed to my success in combatting the dreaded menopausal spread. I had resigned myself to having the middle aged bulge and saying goodbye to any hope of a body. Now, I look better than in high school! In fact, I now purchase clothes in size small or 2/0 sizes. I just feel wonderful all aroind. I use the Bosu to do intervals and pilates style exercises I found on Youtube. I also had a trainer help design a few intervals as well.It was for me very easy to pump with the included hand pump, and I did not have any issues there. The rubber is solid and thick, and the bottom holds well to my hardwood floor. I do my exercises twice a day in front of the television, and it really has added some variety to my exercise routine. Directions were relatively easy to follow regarding inflating. Mine came with workbooks on rehab exercises as well. I look forward to using it for quite some time. I am going to purchase some of the accessories that come with it to help with arm shaping. I also like how portable and does not take a whole lot of space, like my stair stepper. I have used this in the gym for about two months before purchasing the same item to use at home. I love the Bosu, and wanted to make sure I could do my routines even if I did not go to the gym.Admittedly, it takes time to get used to running on the ball, as it requires balance. But, then it really helps with stability and strength. Also, it can be used for arms, core, and leg exercises. Very versatile. Best investment I made to help keep my aging bones and body in as best shape as can be.

this should be standard in all gyms

i first saw the BOSU at the gym i work out, and i knew i wanted one for my home. i purchased this professional model for my home over the home model because i read that home model isn't built as well. this one appears identical to the one at my NYSC gym and i am very happy about that.the ball is easy to inflate with the included foot pump. the included instructional DVD includes a lot of exercises. the base doesn't slip at all due to a MASSIVE circular rubber foot that is made out of some super sticky kind of rubber. the ball surface itself is also very nice and not slippery at all - it feels soft, but durable. the ball and base definitely feel professional quality.doing crunches on the ball feels perfect - almost like getting tazered in the stomach or something. i also did bench press with lighter dumbbells on the ball and it felt very good as well.the ONLY downside i can think of is that when you switch from standing exercises to reclining exercises you may want to wipe the dirt off with a moist paper towel. depending on how clean your shoes are or how dirty your shirt is you may not need to do this, but i found myself doing it.another word of warning i would give is that, because of the constant balancing, it is actually a lot of stress on the ankle to be standing on the BOSU with one foot. this may be good or bad depending on what you're looking for. if you are a young hiker or basketball player perhaps you will enjoy strengthening your ankles, but if you are an older person with problematic ankles you may hurt them. i happen to have a bad ankle so i don't use the BOSU for standing exercises, but that's not the fault of the ball, and i am quite happy with the other exercises i can do on it.in addition to included DVD, you can easily find tons of BOSU exercises on youtube, and i recommend you do so.finally if you're looking to get it for a commercial gym, i saw people in my gym using it as something to sit on between sets. basically it is so versatile in a commercial gym it is guaranteed to find many uses.for home it is quite a large piece of equipment so it may not be for everybody, but i find that it is worth it for me, as you can put it just about anywhere when not in use - i just store mine upside down on whichever couch is not used. for long term storage, or transportation, it could be deflated to quite a flat shape, but i keep mine aired up and ready to use.yes i recommend it and would buy it again. it is my second most favorite piece of home exercise equipment after my PowerBlock Urethane Dumbbells.
