In addition to training the major muscle groups, it's extremely important to give sufficient attention to the supporting auxiliary muscles. This helps to avoid misuse and the resulting imbalances. These can lead to tension and pain, especially at a later stage, which can considerably hinder the success of training. This gymnastic ball is ideal for complementary stability training, body toning and for adding variety to your training routine. The durable material allows for a multitude of exercises, from Gym Ball-Push Ups to Folding Knives and Stability Crunches. Which size is right for me: ; less than 175cm Kötaille &ndash ; Ø ;55cm
