An exercise ball, often referred to as a stability ball or Swiss ball, is a large, inflatable sphere typically made of durable plastic. It is used in various physical activities, including strength training, rehabilitation exercises, and core stability workouts. The ball comes in different sizes to accommodate individuals of various heights and can enhance balance, flexibility, and overall fitness. When used correctly, it can also help improve posture and engage multiple muscle groups during workouts.

Usually crafted from PVC, an exercise ball resembles a large football and is available in various sizes to accommodate your height and individual requirements.

'An exercise ball is mostly used for physical therapy, athletic training and exercise,' says Tim Kayode, sports and performance therapist and Founder of Myoset.

They can assist with bodyweight exercises, enhance your posture, and may even provide relief during labor pains.

What advantages does utilizing an exercise ball offer?

Exercise balls offer a variety of advantages. "They can serve multiple purposes, including workouts, rehabilitation exercises, and stretching routines," says Kayode. However, the perks go beyond just physical fitness.

• Home gym: Don't have space for a gym in your basement? Exercise balls are portable, lightweight and easy to inflate, so you can transform your front room into a gym at a fraction of the cost.
• Core strength: Using an exercise ball activates and engages your stabiliser muscles, which can 'challenge stability and core strength,' says Kayode.
• Budget: Gym membership can get pricey. Exercise balls are an inexpensive way to mix up your fitness routine at home.
• Travel: Globetrotters will be pleased to hear that exercise balls are super easy to inflate and deflate, so they're ideal for holidays or fitness on the move.
• Injury recovery: When used correctly under supervision from a physiotherapist or PT, exercise balls can help you recover quicker from injury.
• Mix it up: A well-chosen exercise ball can be incorporated into a number of fitness routines including yoga, Pilates, resistance training and gym work.
• Pregnancy and labour: Using an exercise ball throughout the trimesters can help to alleviate pregnancy aches and pains and can even ease discomfort during labour.

What is the best type of exercise ball?

Exercise balls come in various sizes, weights, and densities, so it's important to do your homework before making a purchase to find the best fit for your needs. Generally, they are available in several diameters, including 45cm, 55cm, 65cm, and 75cm.

"To start, ensure that the ball is the appropriate size," advises Kayode. "I suggest using your height as a reference." The guidelines below will assist you in selecting the proper size ball:

• 4"8 – small ball (45cm)
• 4"8 - 5'3 – medium ball (55cm)
• 5"4 - 5"10 – large ball (65cm)
• 5"11 - 6"4 – extra large ball (75cm)

Once you've chosen the correct size, it's worth considering exactly what you'll be using your exercise ball for. Do you want it as a stand-in desk chair, able to hold heavier loads while you strength train, or simply as an all-round training aid? Look for features like anti-slip and anti-burst technology, thick, durable materials and consider whether you want extras included, like resistance bands or weighted bases (great if you want a bit of extra stability).

If you are expecting, ensure that any exercise ball you purchase clearly indicates that it is safe for use during pregnancy.

Methods for Testing Exercise Balls

We evaluated various exercise balls by inflating them, sitting on them, and performing core workouts. We tested them on different types of flooring to verify their anti-slip features and observed how quickly they lost air. Fortunately, none of the balls popped — if they had, they wouldn't have passed our selection criteria.

The products that made the list here include exercise balls members of the WH team have owned and used for years, as well as some newer releases we've tested in the last six months.
