In this article, Carl Valle breaks down the physics of flywheel repetition, listing how flywheels differ from traditional weights in constant tension, momentum over gravity, concentric and eccentric speed, eccentric emphasis and skill demand. He also cites studies where flywheel training have led to significant improvements in strength changes, power developments, muscle hypertrophy, jumping performance and improvements in speed. Valle also writes on the eccentric adaptations possible with flywheels, showing athletes can build both strength and injury resiliency over time by adding flywheel training to their program.
