The 65cm two-tone yellow and blue Reebok Gymball is one of the most versatile pieces of exercise equipment for improved all-round fitness, used to perform a wide variety of exercises which will considerably improve your core strength, posture and flexibility. Its weighted base provides additional grip and helps to stop the ball rolling away during every type of exercise.
Though they may appear the same, gymballs come in many diametrical sizes and materials, so it’s important to choose the right exercise ball for you.
The 65cm Reebok Gymball has been manufactured with a high-density rubber to ensure longevity, and is suitable for those between 170cm and 185cm tall (approximately 5’7 ““ 6’1” feet). Selecting the appropriately sized gymball for your body composition is extremely important in ensuring you get the most of out of your workout. By observing the ’90 degree rule’, (where both feet are planted on the floor and knees positioned a little lower than the pelvis, making a 90 degree angle), you’ll discover your ideal gymball size.
