Placing the Magic Circle in between the ankles for Teaser is an appropriate adjustment for?

Placing the Magic Circle in between the ankles during the Teaser exercise serves to increase the level of challenge for the client. This adjustment requires the individual to engage their inner thighs and pelvic floor more actively as they maintain control while using the circle for resistance. The heightened focus on stability and coordination can lead to improved strength in the core and lower body muscles.

By using the Magic Circle, clients must work harder to maintain alignment and balance throughout the exercise, which encourages a deeper engagement of the core. This can enhance the effectiveness of the workout, making it a useful adjustment for individuals who are ready to progress and add intensity to their Pilates practice.

This adjustment wouldn't be suitable for pregnant clients in their third trimester, as the pressure and positioning could lead to discomfort. Additionally, it doesn't specifically address issues such as knee valgus or serve to simplify the exercise, as those goals would require different adjustments.
