During the sitting forward and side reach exercise, which muscles are primarily targeted?

The sitting forward and side reach exercise primarily targets the abdominal muscles. This exercise engages the core as it requires stabilization and control while reaching forward and to the side. The action of flexing at the waist and engaging in lateral movement emphasizes the function of the rectus abdominis, obliques, and transverse abdominis, making them key players in this movement.

While the exercise does involve other muscle groups to a certain extent, such as those in the back for support and balance, the primary focus is on the abdominal muscles, which are critical for maintaining posture and coordination during the reaching actions. This movement not only helps strengthen the core but also enhances flexibility and balance, which are essential components of Pilates practice.
