In "Teaser 2", which muscle groups are primarily engaged?

In "Teaser 2," the primary muscle groups engaged are indeed the abdominal muscles, back extensors, and hip flexors. This exercise requires significant core stability and strength, which is largely reliant on the abdominal muscles. They are responsible for initiating the movement and maintaining control throughout the exercise.

Back extensors play a crucial role in stabilizing the spine during the lift and keeping the back in proper alignment, preventing excessive strain or arching. Additionally, the hip flexors are activated to help elevate the legs and maintain the position of the body, as they assist in lifting the torso while the legs are extended.

The engagement of these muscle groups serves to enhance overall body control and strength, which is fundamental in Pilates exercises. This combination allows for a coordinated movement that challenges both stability and strength, key elements in the practice of Pilates.
