From the team that brought you the Award-Winning Stack System loved by over 45,000 golfers, Dr. Sasho MacKenzie has now applied his years of speed research to create the most effective way to increase your bat speed. Players, Coaches, and Organizations across all levels of baseball can now systematically gain bat speed to hit the ball harder, farther, and have more success at the plate. What’s Inside TheStack Baseball App: * Dynamic Training Programs Customized variable inertia speed training (precision overload and overspeed) - the most efficient way to increase your bat speed. The App responds to your progress and continuously optimizes your training. The algorithms that power dynamic programming come from years of research by leading sports scientist, Dr. Sasho MacKenzie and insights from over 25 million swings from The Stack System golf’s solution. * Your Own Personal Speed Trainer Be guided through scheduled workouts while tracking Stack weight, rest, recovery, and performance gains. This information allows future workouts to be adjusted behind the scenes, so your training is optimized to maximize bat speed gains. * Track Speed, Share Metrics Seamless connection to the Stack Sensor, which is integrated into the TheStack Bat. Train anywhere, anytime. Track key performance metrics such as Stack Speed, Distance Potential, Bat Speed and Grit Score. Easily share your progress and gains. * Connect to Others Easily connect and follow other Stackers' progress and keep each other on track with your training. If you’re a Coach, add your whole team and monitor progress. *** To start speed training, you will need a Stack Bat.
