The exercises are broken into segments to allow you to complete the desired repetitions before moving on. Ten to fifteen reps are a good rule of thumb for each exercise. My wonderful sister, Heidi will demonstrate a few reps of each exercise, and only to one side. Since she's only doing a few, don't think it's ok to stop when she stops, and also remember to do both sides when applicable.
The props you will need are: Foam Roller, Mat, Thera-Band (light to medium resistance). If you do not have these props at home you can improvise and perform the exercises with out props, or skip that exercise. I recommend that everyone have these three props in their Pilates toy box at home.
*Toe Taps can be preformed on the floor without a roller
*Mermaid can be done without a roller
*if you don't have a roller, lie face down, stack hands under forehead like a pillow, extend the spine/arms/head off of the mat by engaging glutes, abs and back muscles
*you can substitute with light hand weights, although band is preferred
And that's a wrap, keep up the good work, and I'll see you in class soon!
