SKLZ Golf Trainer Ball - Self-Guided Stability Ball
Inflation instructions' omission costs 1 star
This ball and others its size take a long time to inflate by muscle power alone. I started by using the little pump that's included in the package and realized after about a hundred pumps that it would take till sometime Thursday around noon (this was on a Wednesday night), so I switched to a full-size bicycle pump. Unlike other reviewers I spent about 45 minutes inflating it.
It is my opinion that it is physically impossible to inflate this ball to its designated circumference by lung power alone. If you disagree please video the accomplishment and post it so we can all see. I tried several times.
Another option is to find a neighbor or service station that can use shop air to fill it relatively instantly, assuming you can make the right connection between valve and valve. ("Shop air" just means that there's a compressor somewhere that fills a tank with air under high pressure that can be released through a hose from that tank as needed.)
No matter what, once you do get it inflated to the right pressure it's a once-and-done deal. The plug on mine fits tightly and has not yet released one cm of pressure in over a month, and it fits tight to the surface of the sphere just as you would want. It's a bit of a struggle to remove it if you want to release some pressure as I needed to, involving in my case a pair of needle-nose pliers and the placement of a wedge thereunder to get sufficient leverage to pull the plug out. Note to people who need to do this: Once the plug is loose the ball will deflate very quickly till it reaches 1 atmosphere of pressure, so be sure the plug does not explode out across your living room and become a cat toy unless you really like inflating this ball.
The directions say to inflate the ball to 80% of the eventual fill size, which is said to be 163 centimeters, let it sit for 24 hours, and then inflate it the rest of the way to its final circumference of 204 cm. First, why? If you know, please leave a comment so the rest of us will too. Second, and more important, measuring such a circumference requires a flexible measuring tape such as is used for sewing, which is all fine and good if you happen to have one, which it happened I did, but I can imagine many people's not having one handy. If you're one of those people, you can almost certainly measure the height of the ball using a yardstick or some other sort of inflexible ruler as long as you know how to convert circumferences to heights, which if you've forgotten you will soon.
If you want to get serious about it, here's how. Lightly place a bubble level on the top of the ball, then center the bubble. Measure down from the bottom of the level to the surface the ball is resting on. A quicker way is to eyeball it, which is very difficult even if you do understand the hazards of parallax error, which you probably don't, but if you're extremely careful you will get a reasonable approximation, which is how I did it because I do understand how serious parallax error can be under these extreme circumstances.
If you want to inflate the ball to a circumference of X cm using a height measurement in inches, here's how.
First, convert from centimeters to inches by multiplying by 0.39371, which is the approximate number of inches in a centimeter. (The exact number is the inverse of 2.54.)
163 cm * 0.39371 = 64 inches (said to be 80% of maximum circumference)
204 cm * 0.39371 = 80 inches (said to be 100% of maximum circumference)
Second, convert the circumference of a sphere to its diameter, starting with R = radius and D = 2 times R. The formula is that the circumference is 2 times pi times R.
64 inches in circumference = 64 divided by pi = 20.37183 inches in diameter
80 inches in circumference = 80 divided by pi = 25.46479 inches in diameter
There you go. The sheet of instructions, which in case you care is exactly four times bigger than it needs to be, could have provided this information at no cost, but it didn't. For this I subtract one star.
This is just an ordinary exercise ball of a certain size that happens to be about 25 inches in diameter. It goes by many names including stability ball, workout ball, Pilates ball, fitness ball, balance ball, training ball, posture ball, core ball, gym ball and Swiss ball.
It has nothing more to do with golf than it does with football or baseball or weight-lifting or basketball or shot-putting or soccer or lacrosse or swimming or diving or wrestling or the pole vault or the high jump or the low hurdles or the broad jump or cliff-diving or boxing or water polo or javelin throwing or water skiing or snow skiing or cross-country skiing or running a mile or bicycling ten miles or roller skating or ice skating or bobsledding or riding a luge or rafting or canoeing or parachuting or beach volleyball or regular volleyball or badminton or scuba diving or skin diving or tennis or ping pong or racquetball or handball or paddleball or rapelling or canoeing river rapids, which are some of the things I have done one way or another, some a little and some a lot.
And certainly including golf. I have played an embarrassingly large number of rounds of golf (in the hundreds) and struck an embarrassingly large number of golf shots (easily in the tens of thousands if you count practice shots) considering how high my handicap is.
The stability ball under review is not only not special to golf, it is also not special to calf-roping (which is evil) or bull-fighting (which is more evil), but I've never participated in those activities.
The manufacturer might as well have called it the SKLZ Quoits Trainer Ball - Self-Guided Stability Ball, which is another sport I've never played. You? I don't subtract a star for this, but it seems like a questionable decision to suggest this exercise ball will help golfers more than, say, crocodile-tamers or astronauts.
The ball otherwise does exactly what it says it will do so I subtract no more stars from 5. I detected no odd smell, and I didn't bother to hand wash it with vinegar and water as the instructions say. I also didn't bless it with holy water or rub it with pesto sauce.

I am no stranger to stability balls. I still have one I bought from another company in 2000. It's still in good shape, too. One must reinflate them occasionally. Like tires, eventually they lose air.
This ball has 16 exercises printed on the side, some for strength building, some for recovery. Recovery is stretching. It's a good workout, and several of the exercises can be done with dumbbells or ankle weights. The exercises shown on the ball may or may not be intuitive to the user. For example, shoulder and lat exercises include Ys, Ts, Ls - and I momentarily forgot the other one because I don't have the ball with me at the moment, but I believe it's a W. Feel free to correct me in the comments if I'm wrong. I know what those exercises are, but only because a friend told me his personal trainer included them in his workout, with excellent results. I had to do a web search to see what he meant, though.
Speaking of web searches, you can find loads of stability ball workout videos on the web, and Amazon sells stability ball DVDs. This is not the only stability ball SKLZ sells. There are several, including this one.
Because this is a Vine review, and I have a limited amount of time to post my review, I can't speak directly to durability. However, this ball seems to be equal in quality to the ball I already own. A stability ball takes up space, but is a small investment for fitness equipment, and a piece that adds a great deal of variety to working out, and we all need that.
One trick I've learned from owning a stabiity ball works great when my back gets stiff. Simply sit on the ball with your feet square in front of you, as though you're sitting on a chair. Gently bounce on the ball for a few minutes. I don't understand the physiology, but it's a great way to loosen your spine when you're tense, or you've been sitting at a desk for too long.
I'm rating this item 3 stars for two reasons. First, the pump included has a very small air chamber - far smaller than the one I got with my other stability ball. In fact, I used the other one to inflate it. Second, the instructions state that if you're short (I am), to underinflate the ball to accommodate your size. That makes it too squishy. This is a 65 cm ball, and there are plenty of 55 cm balls on the market at comparable prices for those of diminutive stature.

I needed a stability ball at the house, because I needed to do more exercising and I can't always get to the gym. This ball works really well and holds up nicely. It comes with instructions on how to inflate and how much to inflate it to. The only thing I wasn't happy about is something that other reviewers mentioned...the pump. Oh man, the pump. It's awful. Takes F O R E V E R to inflate. I didn't have another way to inflate it, so let's just say I got some arm exercise in! Overall, though, it's a good product!

We were hoping for a great extra workout tool but instead got the workout just keeping the thing inflated.
We read through the directions when it arrived and thank goodness we did, because it states to inflate in increments rather than all at once and wait 24 hours in between each step. We followed it to a "t'.
When that was done, both my husband and I went through the steps of each exercise, which is printed on the ball itself. Most were easy to interpret with the drawings and limited printed directions. Some were confusing and we are still unsure of what to do. But we had a lot of fun laughing at how silly we looked.
The second time we came back to the ball, it had lost some air. We fought with the plug, filled it up and after two tries, finally got the plug back in. The third time, same thing. It was such a pain to refill each time that it became a great play toy for my 7 yr old son. He doesn't mind that the giant ball is a little squishy.
For someone who has the time and wants to make the effort to refill it every time they use it, it would be a great extra bit of equipment in a home gym or workout routine. But for a busy family, it is just a little too much.

I have several inflatable balls from different companies. I have to say this one is pretty high quality, especially when compared to the "cheaper" ones. I don't use it for Golf training but am very pleased with the thickness of it.
