Baseball - pitching and throwing
While throwing a baseball is usually thought of requiring strong arm strength, it really requires much more than that. Before you can put good arm strength into the ball you need to have good core strength and control, otherwise there is little support and the ball will move with much less speed and accuracy. This is especially true when the feet are not well engaged with the ground. Or, when a pitcher is trying to throw with both the maximum velocity and control. Look at the top picture and see how the core has to be well engaged to throw the ball with any force. Then, look at the pictures of All-Star pitcher (and PowerCranker) Randy Johnson. Look at how he has to engage the hip flexors in raising the leg then how the core is engaged and twists to throw the ball. Pitchers are used to working on their hip flexors but PowerCranks allow them to do this much more effectively. PowerCranks have been used by rehab professionals, like Fischer Sports in Tempe Arizona, on such notable pitchers as Randy Johnson to help prolong his career. PowerCranks can be used to develop your core strength and coordination more efficiently and better than any other training method. 10-20 minutes 2-3 times a week (alternating between strength workouts and coordination workouts) is probably all that is necessary for most people for this baseball purpose.
