Athletes can tone their abdominals, arms, legs and backs all with one simple exercise tool: the medicine ball. These balls are roughly the size of the user's shoulders and made of leather or vinyl material. They should not be confused with yoga balls, which are much larger and far less dense. Exercise balls have been used in fitness routines since the days of ancient Greece and are still seen in millions of fitness facilities and home gyms today.
Users can complete a wide range of exercises with fitness balls. The Medicine balls are great for abdominal exercises, or can be thrown in the air to work the arms and core. By placing a ball between the knees and squeezing it, users can greatly strengthen their inner thighs. Medicine ball exercises are easy to do, and can be completed almost anywhere. This classic piece of equipment will surely remain popular for years to come.
