Exercise ball – your all-round tool for fitness, health and posture

An exercise ball is a versatile piece of exercise equipment used in a variety of settings, from physical therapy to the gym. It promotes stability , strengthens muscles , and improves posture . This comprehensive guide will teach you everything you need to know about exercise balls, including their benefits, uses, and selection criteria.

What is an exercise ball?

An exercise ball, also known as a Pezzi ball or fitness ball , is a large, inflatable ball made of elastic plastic. Originally developed for physical therapy, it has now established itself as a popular training tool in the fitness sector. Its instability challenges the core muscles and improves balance .

Benefits of an exercise ball

1. Strengthening the deep muscles

The instability of the ball forces the body to constantly make small compensatory movements. This activates the deep muscles, especially in the core area, thus promoting stability and posture.

2. Improve posture

Regular exercise or sitting on an exercise ball can prevent posture problems and alleviate existing problems. The upright sitting position strengthens the back muscles and relieves pressure on the spine.

3. Versatile training

The exercise ball is suitable for a variety of exercises, including abdominal training, balance exercises, and stretching. It can be used both in the gym and at home.

4. Use in rehabilitation

In physiotherapy, the exercise ball is used to restore mobility and strengthen muscles after injuries. Its joint-friendly properties make it ideal for rehabilitation.

Which exercise ball for which body size?

A common problem when buying an exercise ball is choosing the right size (diameter). Body size is a crucial factor for the optimal fit—and thus for effective, safe exercises. Only with the right ball can you achieve the correct sitting position, an ergonomic posture, and the desired training effect.

✦ up to 140 cm: ⌀ 45 cm

✦ 141 - 155 cm: ⌀ 55 cm

✦ 156 - 175 cm: ⌀ 65 cm

✦ 176 - 185 cm: ⌀ 75 cm

✦ from 186 cm: ⌀ 85 cm

When sitting on the ball, make sure your thighs are parallel to the floor and your knees are bent at approximately a 90-degree angle . This is the only way to properly relieve pressure on your spine and promote healthy sitting posture – whether during training or when using it as an ergonomic exercise ball in the office. A ball that's too small or too large, however, can lead to poor posture, reducing both the effectiveness of the exercises and the health benefits. Therefore, when choosing a ball, it's worth paying attention not only to the diameter, but also to the maximum permissible weight and the material's elasticity – two quality features that our exercise balls meet as standard.

High-quality materials and workmanship for safety when training with the exercise ball

When choosing an exercise ball, the quality of the material and workmanship play a crucial role – especially if the ball is used regularly in a home gym, studio, or therapeutic setting. Our exercise balls are made from particularly durable, elastic rubber or, optionally, high-quality synthetic leather. Both versions are characterized by excellent grip, providing a secure hold even during strenuous workouts. This not only increases the quality of your training but also minimizes the risk of slipping during exercise. Thanks to their easy-care surface, our exercise balls are effortless to clean – a major advantage for daily use, especially in professional environments such as physiotherapy practices or fitness studios. The materials are also resistant to mechanical stress, UV light, and moisture, which significantly extends the lifespan of the ball.

Particularly noteworthy is the anti-burst technology used in many of our models: Even under heavy loads, the balls retain their shape and do not burst suddenly, but rather escape in a controlled manner if damaged – an important safety aspect for dynamic exercises or rehabilitation sports. Our exercise balls undergo strict quality controls and meet the highest safety standards – for effective yet safe training that allows no compromises. Whether core training, spinal exercises, or functional fitness: the material and workmanship are crucial – and this is precisely where we focus on uncompromising quality.

What does an exercise ball do? – The versatile effects on body and posture

An exercise ball is much more than just an inflatable ball – it's a multifunctional training tool that has a permanent place in almost every fitness and rehabilitation program. Its effects unfold on multiple levels: from improving posture and targeted muscle building to promoting coordination and balance .

1. Improve posture and stabilization of the spine

One of the greatest advantages of the exercise ball is its unstable surface. This forces the body to constantly perform minute compensatory movements – particularly activating the deep muscles around the spine. This effectively corrects poor posture, prevents back pain, and sustainably improves core stability.

2. Effective core training

The exercise ball is the ideal tool for intensive core training—that is, the abdominals, back, and pelvic floor. Exercises like crunches, planks, and hyperextensions on the ball place significantly more strain on the deep core muscles than static floor exercises. The result: a stable core, better body control, and a strengthened lower back—the foundation for virtually any athletic movement.

3. Improve coordination and balance

Balance exercises on an exercise ball specifically train neuromuscular interplay and promote proprioceptive abilities—the body's ability to perceive its position in space and react accordingly. This is of enormous health value not only for athletes, but also for seniors, rehabilitation patients, and office workers.

4. Use in rehabilitation and physiotherapy

In therapeutic practice, the exercise ball is a proven tool for restoring mobility and muscle strength after injuries or surgeries. The adjustable load makes it ideal for building muscle without stress on the joints—for example, in cases of back problems, herniated discs, or poor posture.

Is an exercise ball good for belly fat? – How the ball helps with fat loss and body toning

Many people ask whether an exercise ball can specifically help with belly fat – and the answer is: Yes, with the right training, an exercise ball can be an effective tool for reducing belly fat and toning the core. While it's physiologically impossible to burn fat exclusively in one specific area ("spot reduction"), an exercise ball offers ideal conditions for activating the entire core muscles, increasing calorie consumption, and stimulating fat metabolism .

1. Activation of the deep abdominal muscles

Exercises on an exercise ball, such as crunches, V-sits, planks, or Russian twists, challenge the abdominal muscles more intensively than traditional floor exercises. The unstable surface forces you to constantly stabilize your entire core – this engages not only the rectus abdominis, but also the lateral and deep abdominal muscles. This promotes muscular development and visibly improves core tone.

2. Higher calorie consumption due to unstable training conditions

A key benefit of training with an exercise ball is the increased energy expenditure. Because the body constantly has to perform small compensatory movements to maintain balance, it burns more calories than with static exercises. Combining these exercises with a healthy calorie deficit in your diet can effectively reduce fat reserves—especially in the abdominal area.

3. Motivation through versatility and fun factor

Not to be underestimated: The exercise ball is fun – and therefore motivates you to exercise more. This promotes training consistency, which is ultimately crucial for any fat loss. Whether for short home workouts, targeted abdominal exercises, or dynamic interval training: the ball adapts to your fitness level and can be used anywhere.

What is the best exercise ball?

The best exercise ball is the one that suits you and your training goals. Important selection criteria include:

I. Size: tailored to body size

II. Material quality : non-slip, elastic, durable

III. Load capacity : at least 120 kg, ideally 150 – 200 kg

IV. Anti-burst system : protects against bursting in case of overpressure

V. Surface structure : for optimal grip
