Exercise balls – practical tips for selection and maintenance


Exercise balls – practical tips for selection and maintenance


An exercise ball is a simple yet effective tool that can be used for everything from strength training and stability exercises to rehabilitation and stretching. It challenges balance, activates the core muscles, and can be used both at home and in the gym. With the wide range of sizes, materials, and features available, it can be difficult to choose the right ball for your needs.
In this article, you’ll get an overview of what to consider when choosing an exercise ball, how to maintain it, and which types and brands are available on the market.
The article presents a selection of exercise balls in different sizes, materials, and price ranges. The aim is to provide a broad overview of the available options so you can more easily find a ball that suits your training style and body type. The product information is based on publicly available descriptions from manufacturers and retailers and is summarised to provide a clear and informative overview.
Factors to consider when buying an exercise ball
When choosing an exercise ball, it’s important to consider size, material, load capacity, and intended use. Here are some of the most important factors to keep in mind.
1. Size and height
The size of the exercise ball should match your height. As a rule of thumb, you should be able to sit on the ball with a 90-degree angle in your knees. Typically, a 55 cm ball suits people under 165 cm, a 65 cm ball suits people between 165–185 cm, and a 75 cm ball suits people over 185 cm.
2. Material and slip resistance
Most exercise balls are made of PVC or similar elastic materials. Choose a ball with anti-burst technology, which ensures it doesn’t explode if punctured but instead slowly deflates. A non-slip surface provides better stability during training.
3. Load capacity
Check the maximum weight capacity, especially if you plan to use the ball for strength training or as an office chair. Most quality balls can support between 250 and 500 kg, but this varies from model to model.
4. Intended use
Consider how you primarily plan to use the ball. For core training and balance exercises, a standard ball is ideal, while a half ball (Bosu) is better suited for functional training. For office use, choose a ball with a stabilising ring or feet.
5. Maintenance
Keep the ball clean by wiping it with a damp cloth after use. Avoid sharp objects and store it in a dry place away from direct sunlight. Check the air pressure regularly and inflate as needed to maintain the right firmness.
