- More muscle activation
- Coordination
- Functional strength
- More time under tension
- More hypertrophy
- Greater range of motion
This variation adds rotation, which requires more muscle and fiber activation and coordination. It also simulates the rotational movement you use everyday such as throwing, passing, closing a heavy door, getting a car seat out of the car, etc. The rotational chest press is a little harder than a regular Chest Press due to a slight increase in time under tension, so you may not be able to lift quite as much weight.
Rotation provides the main working muscle, the pectoralis major, a more focused and isolated contraction and works over a greater range of motion. The muscle is lengthened in the bottom position and shortened in the top position. This greater range of motion stimulates more muscular hypertrophy.
