Hi, I'm Amy Newman, fitness expert and creator of the Perfect 10 workout. We're going to do a lot of reps of these, but pretty much the same exercise, over and over, to help our core get nice and strong, because that's what we're going to do, is work the core with some Pilates exercises on the stability ball. We're going to lay on the ball with our knees bent. With our hands behind our head, we're going to round back. Then we're going to lift up, exhaling as we exert. Inhale as you relax, exhale as you exert. Inhale as you relax, round down into the ball, exhale as you exert. Inhale as you relax, exhale as you exert, doing many repetitions of that. Then roll to your side. You're going to work on both sides. You're going to lay on your side, you're going to anchor yourself with your bottom leg, and your foot is sideways. Arm is going to come over. We're going to stretch and crunch. Stretch and crunch. Exhale. Stretch and crunch. Exhale. Inhale. Exhale. Inhale. Exhale. Inhale. Exhale. Then you can lift up both legs, balancing, with your hand on your head, and do little crunches. One, two, three, four... little tiny crunches that make that awesome line in your abdominal area. I'm Amy Newman, thanks for joining me as we do Pilates core ball exercises.
