What position should the legs be in during the initial phase of the "Hundred"?

During the initial phase of the "Hundred" exercise in Stott Pilates, the legs should be parallel and adducted in the air. This position is crucial for engaging the core muscles effectively while maintaining stability and connection to the mat or reformer. Keeping the legs in this position helps promote proper alignment and encourages the use of the abdominal muscles to control movement.

In this setup, having the legs parallel and adducted allows for a stronger connection through the center of the body, which is a fundamental aspect of Pilates practice. It supports the breath pattern associated with the "Hundred," where participants pump their arms while breathing in a specific rhythm. This strategic alignment not only maximizes the workout's effectiveness but also minimizes the risk of strain or injury.

The alternative positions listed do not support the same level of core engagement or stability required for this particular exercise. Therefore, the chosen position optimizes the benefits of the "Hundred," reinforcing foundational principles in Pilates such as core strength and proper body mechanics.
