How to choose an exercise ball that suits your body and training


An exercise ball is a versatile tool that can be used for everything from strength training and stability exercises to rehabilitation and office use. The right ball can improve your balance, strengthen your core, and make your workouts more effective. But with many sizes, materials, and types to choose from, it can be difficult to find the one that best suits you and your needs.
In this article, you’ll get an overview of what to consider when choosing an exercise ball, as well as an introduction to the different types and brands on the market.
The article presents a wide selection of exercise balls representing different sizes, materials, and features. The aim is to provide an overview of the options so you can more easily find a ball that suits your body and training style. The product information is based on publicly available descriptions from manufacturers and retailers and is summarised to give a clear and informative picture of the market.
Factors to consider when buying an exercise ball
When choosing an exercise ball, it’s important to consider size, material, and intended use. Here are some of the most important factors to keep in mind.
1. Size and height
Exercise balls typically come in sizes from 45 to 85 cm in diameter. The right size depends on your height:
- Under 160 cm: 55 cm ball
- 160–180 cm: 65 cm ball
- Over 180 cm: 75 cm ball
When sitting on the ball, your knees should be at a 90-degree angle for optimal support and balance.
2. Material and anti-burst function
Most exercise balls are made of PVC or similar rubber material. Choose a ball with anti-burst technology, which ensures it slowly deflates instead of bursting if punctured. This increases both safety and durability.
3. Load and weight capacity
Always check the maximum weight capacity. Standard balls can typically support up to 120–150 kg, while professional models can handle up to 300 kg. If you plan to use the ball for strength training with weights, choose a model with high load tolerance.
4. Surface and grip
A rough or textured surface provides better grip, especially if you use the ball on smooth floors or during sweaty workouts. Smooth balls can be good for office use, where you sit on the ball for longer periods.
5. Area of use
Consider how you primarily intend to use the ball. For home workouts and core exercises, standard balls are often sufficient. For physiotherapy or intensive training, a professional model with extra stability and higher weight capacity may be beneficial.
6. Price and quality
The price depends on material, size, and brand. Cheaper models can be fine for light training, while more expensive balls often have better durability, thicker material, and higher comfort. Consider how often you’ll use the ball when choosing.

Different types of exercise balls
Exercise balls come in many varieties, each suited to different purposes and training levels.

The traditional exercise ball is used for core training, stability exercises, and as an alternative to an office chair. It’s ideal for beginners and for versatile use at home.

3. Peanut balls
These elongated balls are shaped like a peanut and provide extra stability in one direction. They are suitable for rehabilitation, physiotherapy, and exercises where more control is desired than with a round ball.
4. Mini exercise balls
Small balls of 20–30 cm are often used for pilates, yoga, and core exercises. They are easy to store and allow for precise movements and support in specific positions.
5. Weighted exercise balls
Some balls contain weight filling, providing extra resistance during training. They are mainly used for strength exercises and can be a good supplement to traditional training.

Frequently asked questions
How do I find the right size exercise ball?
The size depends on your height. When sitting on the ball, your hips should be slightly higher than your knees, and your feet should rest flat on the floor.
Can I use an exercise ball as an office chair?
Yes, many people use exercise balls as an alternative to office chairs to strengthen core muscles and improve posture. However, it’s best to alternate between the ball and a chair to avoid overstrain.
How much air should be in the ball?
The ball should be firm but still give slightly when you sit on it. Overinflated balls can feel unstable, while too soft balls reduce the effectiveness of exercises.
Can exercise balls be used during pregnancy?
Yes, many pregnant women use exercise balls for light training and relaxation. They can help relieve back strain and improve posture, but it’s important to choose a stable ball and consult a professional.
How do I maintain my exercise ball?
Wipe the ball with a damp cloth after use and avoid sharp objects nearby. Store it at room temperature and inflate it as needed to maintain the right firmness.
