Fitness balls for functional training and body control


Fitness balls for functional training and body control


Exercise balls are a versatile tool that can be used for everything from rehabilitation and core training to strength exercises and balance work. They challenge the body's stability and help activate the deep muscles that are often overlooked in traditional strength training. Whether you train at home, in the gym, or as a supplement to sports, an exercise ball can be an effective and inexpensive tool to improve your body control and functional strength.
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 selection of exercise balls in different sizes, materials, and price ranges. The aim is to provide an overview of the most important features and functions so that you can more easily find a ball that suits your training style and level. 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 take into account both size, material, and intended use. Here are some of the most important factors to consider.
1. Size and height
The size of the exercise ball should match your height to ensure correct posture during training. As a rule of thumb:
- Under 160 cm: 55 cm ball
- 160–180 cm: 65 cm ball
- Over 180 cm: 75 cm ball A correct size makes the exercises more effective and reduces the risk of injury.
2. Material and durability
Most exercise balls are made of PVC or similar elastic materials. Choose a ball with anti-burst technology, which ensures that it doesn’t explode if punctured but instead slowly loses air. This increases safety, especially during strength exercises with weights.
3. Non-slip surface and comfort
A good exercise ball should have a non-slip surface so you remain stable even on smooth floors. The texture of the surface also affects comfort – a slightly rough surface provides better grip, while a smooth surface can feel more comfortable for floor exercises.
4. Maximum load
If you plan to use the ball for strength training or as an office chair, you should check the maximum weight capacity. Many quality balls can support up to 300 kg, providing extra safety and stability.
5. Accessories and pump
Some exercise balls come with a pump, measuring tape, or training guide. This can be an advantage, especially if you’re a beginner and want inspiration for exercises.

Frequently asked questions
What can you train with an exercise ball?
An exercise ball can be used for core training, balance exercises, strength training, stretching, and rehabilitation. It activates stabilising muscles and improves coordination and body control.
How do I choose the right size?
The size depends on your height. When sitting on the ball, your knees should be at a 90-degree angle. Use the size guide as a starting point and try different sizes to find the most comfortable one.
Can an exercise ball be used as an office chair?
Yes, many people use exercise balls as an alternative to office chairs to improve posture and activate the core muscles. However, it’s recommended to alternate between the ball and a chair throughout the day.
How do I maintain an exercise ball?
Keep the ball clean with a damp cloth and mild soap. Avoid sharp objects and direct sunlight, which can weaken the material. Check the air pressure regularly and inflate as needed.
How long does an exercise ball last?
The lifespan depends on use and quality. A good-quality ball can last for several years with proper maintenance. Always check for wear or small cracks, especially if you use it frequently.
