What is Pilates?
Pilates is a form of low-impact exercise that aims to strengthen muscles while improving postural alignment and flexibility. Pilate’s moves tend to target the core, although the exercises work other areas of your body as well.

How is Pilates different from other forms of workouts?
Pilates is different from most exercises out there because it's non-impact and safe, and it really works on using the body as a whole. You're either lying on your back, on your side or kneeling on the floor where it's safe. When you move the body, you're trying to move it from the powerhouse, using your abdominal wall to protect your back. You're also working the body very evenly and symmetrically, making sure one side is not working harder than the other.

What is the key difference between yoga and Pilates?
There's definitely a mind-body connection and a very similar fluidity in both. But one difference is that there's a whole line of equipment in Pilates that doesn't exist in yoga, so it provides a different angle: You're doing exercises with the assistance and resistance of springs and pulleys. The springs may assist you or they may make an exercise more difficult, depending on the exercise.

How often should I do Pilates? Is it like weight training where I have to rest my muscles in between for 48 hours?
Pilates is safe enough to do every day. Initially you may want to do it every day so you get a rhythm and become consistent; then a good goal is to do it every other day. Joseph Pilates used to say to do it three times a week.
