Roll Ups
This exercise comes directly from the Pilates Roll Up. It is an exercise for the deep abdominal, the Transversus Abdominis.
We bring to the table a couple of innovations: We do the roll ups with our feet of the edge of a table, which allows us to hang a sandbag over the ankles. A sandbag on the ankles makes the exercise easier for beginners. We have also found that a foam roller gives some nice proprioceptive feedback.
Finally, getting onto our stretching table is much more convenient than getting down on the floor. Little conveniences like this create a smoother exercise flow.
