What is the primary muscle focus during the 'Saw' exercise?

The primary muscle focus during the 'Saw' exercise is the obliques. This exercise is designed to promote rotation and flexion of the spine while engaging the muscles of the core. The obliques, located on the sides of the abdomen, play a crucial role in stabilizing the torso during the exercise and facilitating the rotational movement required to reach towards the opposite foot.

In addition to the obliques, the exercise also engages other core stabilizers, including the rectus abdominis and the transversus abdominis, but the obliques are particularly emphasized due to the twisting nature of the movement. Moreover, the 'Saw' helps improve spinal mobility as well as promote awareness of the breath and alignment during dynamic movement. Enhancing the strength and coordination of the obliques is important for overall core strength and functional movement patterns.

The other choices highlight important muscle groups involved in different exercises but are not the primary focus of the 'Saw.' For instance, while the hamstrings contribute to the stabilization of the pelvis, they are not the main target. Similarly, the abs as a whole assist in the exercise, yet they do not provide the rotational support that the obliques specifically offer. The upper back extensors might be
