Which of the following are considered advanced Reformer exercises?

The "Teaser" and "Long Box Swimmer" are considered advanced Reformer exercises due to their complexity and the significant strength, stability, and control required to perform them effectively.

The "Teaser" involves balancing the body while lifting the torso and legs simultaneously, which demands a high level of core strength and coordination. This exercise challenges the abdominal muscles intensely and often requires experience to maintain proper form throughout the movement.

The "Long Box Swimmer," performed on the reformer, also requires substantial skill. It involves a combination of arm and leg movements while maintaining stability and control of the core on the long box. This complex movement places emphasis on back extension, coordination, and the proper alignment of the body, making it suitable for those with a strong foundation in Pilates.

In contrast, the other options consist of exercises that are typically regarded as intermediate or foundational movements, where the focus may be on building strength and mastering form rather than the advanced integrative challenges presented by the "Teaser" and "Long Box Swimmer."
