Reebok Gym ball - Versatility for improved all-round fitness. Possibly one of the most versatile and accessible pieces of training equipment, a gym ball can be used to perform a wide variety of exercises which will considerably improve your core strength, posture and flexibility. Though they may appear the same, gym balls come in many diametrical sizes and materials, so its important to choose the right exercise ball for you. The 75 cm Reebok Gym ball has been manufactured with a high-density rubber to ensure longevity, and is suitable for those 188 cm or taller (approximately 62). Selecting the appropriately sized gym ball for your height 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), youll discover your ideal gym ball size. It’s also important to note that your height alone isn’t the only factor in determining the right ball size. As Reebok exercise balls are flexible and offer resistance, weight is also an important factor. Supporting your ab crunches, triceps dips and planks, the grey gym ball features anti-burst technology, meaning if the ball happens to puncture during your workout, it will slowly and safely deflate to avoid any possible injuries. Every Reebok Gym ball ships with a kit which includes the fundamental pump. And, if you’re in need of a little inspiration to kick start your gym ball workout, this gym ball comes complete with its very own workout DVD. As part of the Reebok Men’s Training range, the Reebok Gym ball also comes in a 65cm size. Targeted Group: Unisex
