Exercise balls for sale can be found everywhere from discount stores to sporting goods stores. Quality and specifications may vary widely. Some balls are made of vinyl, while others are made of plastic.
Some exercise balls are slightly floppy, making them softer, while others have a very hard surface. Softer balls are usually a good choice for beginners because they offer slightly more stability than hard surface balls.
However, if you use exercise balls for a variety of exercises, it's always better to opt for more expensive and high-quality yoga balls. These types of exercise balls are heavier and usually last longer.
Finding the right ball can be tricky when shopping for an exercise ball, especially since you often can't tell what the ball will look like until you inflate it.
However, there are a few features you can look out for before buying that will help you stay safe while exercising:
Tear Resistance: If you plan to use the ball for strength training and other exercises, you need a ball that won't burst if accidentally punctured. Instead, the air escapes slowly, so you don't risk hurting yourself.
Durable: The thicker the material of the ball, the stronger it is. For example, the Trideer exercise ball is rated "gym quality" with a blast weight of up to 330lbs.
Specifications: The right size for your height is important for a safe and effective workout. See the size chart below to find your size.
When choosing an yoga exercise ball, make sure you choose the correct size for your height. Your knees should be at or slightly below your hips when you're sitting on it (although you may need a larger exercise ball if you're going to use it while sitting in front of a computer).
You can use the table below to help you choose the right ball for you, but keep in mind that all exercise balls are made of different materials and have different stiffnesses, so sizes may vary by brand.
Ball 45cm: 4'6" to 5'0" high
55cm: 5'1" to 5'8"
65cm: 5'9" to 6'2"
75cm: 6'3" to 6'7"
If you're concerned about getting the right size, it's better to choose more than less. You can usually return the ball if it's the wrong size.
