I used to work out to Jillian Michaels every day, but a few months ago I developed an illness that causes terrible pelvic pain, so Jillian Michaels was out of the question. I quit working out for about 4 months and this is the first thing I tried when I got back to working out. I'm only 20, but so far this DVD has been pretty good for me. It is a little slow at times but its good for getting down the basics of pilates/yoga and developing your core and flexibility before you move on to the advanced stuff, and I can feel my core getting stronger when I do it. This DVD also comes in a 3 pack with pilates sculpt and tone and pilates for weight loss, and this video is the perfect stepping stone to being able to complete those.
