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.
(Note: this is designated as a 'Golf Trainer Ball' but is no different from similar stability balls and could be used for any kind of ball training.)
An exercise ball is one of those simple pieces of gym equipment that allow you to enhance a number of exercises. You can do body weight exercises or even lift weights on the ball. In order to maintain balance, you need to engage your core muscles. This not only challenges you, but adds variety to your regimen and makes your core stronger.
Inside the package you will find the ball, a plastic stopper pin, and the requisite, cheap filling pump. I had high hopes for the pump when I opened the package. It looked like it would hold up but had two problems. 1) the cylinder--as with most such pumps--is very small. This means that it will take a great deal of time and effort to fill the ball. 2) The tip fell out after filling the ball half way. Sure, I could reinsert the tip, but after doing so air leaked around the tip making the pump useless. The provided tip was an odd size and did not fit into my bicycle pump. Happily, I had an extra tip that came with the pump for filling such things. In any event, the cylinder length of the bicycle pump was more than 3 times the length of the ball pump--this translated into much faster filling.
Once inflated the ball behaved like most exercise balls. It fared well in comparison to a smaller Go-Fit ball that I had bought previously. However, both the SKLZ and Go-Fit ball were not as thick walled and firm as my Gaiam ball. I prefer a firmer ball, because the firmer balls require more balance and therefore I feel that they require me to engage more muscles for balance. Firmness of a ball, however, is a matter of preference. The SKLZ ball is rated to '500+' pounds, which means that most will be able to use the ball in conjunction with lifting weights.
There are a number of exercises printed on the side of the ball. These are not all encompassing, nor to they constitute a full routine. This is designated as a 'Golf Trainer Ball' but the printed exercises were not golf centric and could be used for any kind of sports training. It's nice to have them there, I suppose, but for me it didn't really add value.
All in all this is a fine exercise ball and certainly performs as expected.
It is always recommend to ask your doctor before starting any new exercise program. My doctor fuly approved for my bad back. I an 5 ft 11 inches and the ball I had was way to small this is a perfect fit. The color is a nice dark teal not grass green. Great tool for balance and strengthening core to improve posture and strength.
There is a strong plastic/vinyl odor but it dissipates in 48 hrs. It is for people up to 6ft 2 inches and 500 pounds.
