The Pilates series of five is a popular sequence of Pilates mat ab exercises that you can put in any workout you do. If you are basically following the classical Pilates mat sequence, the series of five goes between rolling like a ball and spine stretch.
Below is an quick reference for the series of five. The basic instructions for each exercise are there accompanied by a photo. Click on the photos to make them larger and be sure to check the detailed instructions for each exercise at least once.
Notes on form. Most people agree that these are some of the best ab exercises of all time. Yes, they are challenging. You can modify them by not taking your legs too low and/or keeping your head down. There are modifications for these exercises included in the detailed instructions.
In general, use your abdominal muscles to keep your upper body curl, to stabilize your pelvis, and to move the legs from your center. Do not take your legs any lower than you can control the movement from your abs and keep your back from coming off the mat. Your pelvis must stay stable.
Some people teach the series of five with no break between exercises holding the upper body curl the whole time. This is only for the most advanced people. Excessive muscle fatigue is not part of Joseph Pilates' method. Put your head down, if briefly, between exercises. Keep all of your Pilates Principles in mind.
