It is good.

When entering the air, it was difficult to enter the air without pushing air in while holding the air hole part securely. Once the air enters, it will not come out. I am using it fun.

It's easy to use.

I was looking for something of 30 cm in size. Finally I found and ordered immediately. It has sand in it and it is very easy to use with moderate weight. Since the fixing ring is also attached, it can be fixed and can be done without anxiety. I became a favorite totally.

New sense of weight

Since we were using ordinary balance balls of the same size, we felt that the weight of sand of only 1 km was unexpectedly heavy compared to it. Because the stopper ring is attached (because muscular strength is particularly weak), I think that it is easy to do the training that was difficult until now because the ball does not roll. The size is also 30 cm slightly compact. It was better if this price included a book or DVD.

It is strong and has a sense of stability

Balance ball is essential for everyone to have one by one, but here is the first size feeling. Making is solid, material is also thick, so it is strong. A sense of stability that seems to absolutely last long! It is also the first time that this stand is attached. It does not move and some things you want to fix by exercising are very good! Because it is a small size, I can not move and do not lean, but looking at the contents of the exercise, they are all attractive. It is easy, but it works quite well, and it is tough on a stabbed body. . Whether it is contents from trunk / core care system rather than relaxation. I think. I will price a bit too, but it is strong, it is perfect for those who want to try the method of a professional player!

It was not likely

Balance balls are my favorite, I am also learning yoga. There was a balance ball with balance, until now, this might be nice. The load is moderate with a moderate weight of 1 kilometer, and the effect is great for the movement that it makes me feel about the inner muscle. The price is a bit high, but the size is not too big, it can be placed in a corner of the room.

Just a good size.

It is good that it is a product born with Mr. Nagatomo involved in active soccer player. Yoga ball has a big image, but this ball is small and easy to handle. It comes with a fixed ring and exercise guide, so it comes in handy. You can relax even whole stretches that you can not ever stretch. It takes days to master it, but it seems to be good for your body if you can continue every day little by little. Different colors are out, but every color is nice. It is likely to appear in the trendy drama scene.

It seems that there will be no effect though there are fewer menus than for a good price

I was expecting good quality from Taiwan but I thought that cleanliness is necessary before using it because the balls and base are sticky. The copy of Nagatomi method is good, but the exercise menu is only the attached booklet, it is wonderful, there is description of the booklet attached also on the WEB page, it is disappointing. I enlargedly copied the booklet and tried to do it carefully, but I could not understand how to use and position each part of the body, I am anxious. If you do not have trainer guidance DVD etc, it will be self-flowing Yes, it is over. Because I take up places to get tired and clean up, is it like removing the air and packing it as it is and decorating it as it is? After several uses, the ball's tapes can not be removed even if it is cleaned, it seems that it might be a coating for not sliding, but the exercise menu of the instruction manual, there is not much tightness, but I will do it thoroughly It takes quite long time, the comfort of the weakness menu is exceptional and I will try again.

Size that does not get in the way

Because it is 30 cm in diameter, it is better not to get in the way too much even if it is placed in the room. I am happy to choose a relatively large number of colors. I inflated the pedestal in 10 minutes and it was easy. Since the check valve is not attached, when pushing out the pump, I pressed it with a finger to keep the air out so that it would not come out. The odor was also written in the note, but there is a vinyl smell. It was reduced considerably after about a week. Somewhat comfortable to touch, but something does not stick to the hand, it is easy to hold. Because it contains sand, it is good not to roll. Although it is the essential training effect, it is likely to use it like a seat chair rather than ... But still it uses the muscles to balance, so I feel that I consume energy rather than sitting on the floor normally. Of course I will do training as well. Because explanation booklet is attached, even those who do not know how to do it is okay. Thanks to the sand of 1 kilometer, just raising the ball up and down makes the arm slump. I also have a large balance ball, but the presence is still great. Regarding training, I can not say which is better, because I can not say which one is good, but if there is one in the room I can train at a moment and I think that it is easy for beginners of balance balls to start with if this is the case.
