Flywheel Training: A versatile approach.
Strength and preventative conditioning for the throwing athlete.
Absorb, load and explode the inertia flywheel provides patented acceleration/deceleration loading.
For any athlete throwing a ball, the shoulder and joint muscles receive a tremendous amount of mechanical stress. With that being said, the coach should have a pre-hab program in place to reduce the imbalances that lead to injury and increase focus on muscle groups responsible for deceleration. The two rotator muscles responsible for deceleration are the posterior shoulder muscles infraspinatus and the teres minor. Throwing puts the shoulder into high speed and power internal rotation. An imbalance often occurs, between the anterior and posterior shoulder muscles due to constant throwing. The anterior accelerator muscles in the front of the shoulder become over trained, while the back of the shoulder is relaxed. Most injuries occur in the back of the shoulder after the ball is released during the deceleration phase. The VersaPulley's inertial flywheel is a perfect solution to train this power imbalance because of the need to accelerate, then decelerate—stopping to absorb the load. The flywheel allows the athlete to train for deceleration loading—which effects all facets of the shoulder.
1. External Rotation at 0 Degrees (Abduction)
  • Stand with shoulder abducted 90 degrees and elbow flexed 90 flexed.
  • Grip the handle, slightly lower than the shoulder.
  • Keeping shoulder abducted, rotate the shoulder back, keeping elbow at 90 degrees and pull arm across the front of the body.
The benefits of performing this move on the inertia flywheel are the VersaPulley is 100 % compliant to the user, meaning they will never pull more than they can. And second the flywheel makes the athlete decelerate with an eccentric load.
2. Internal Rotation at 90 Degrees (Abduction)
  • Stand with shoulder abducted to 90 degrees, externally rotated 90 degrees and elbow bent 90 degrees.
  • Keeping shoulder abducted, rotate shoulder forward, keeping elbow bent at 90 degrees.
