So I'm going to demonstrate how to do the Pilates 100 for you. So you're going to get into a position on your back. You're going to bend your knees at 90 degrees. You're going to engage your core, lift your arms. You're going to inhale, tuck your chin under as if you had a tennis ball under your chin and you're trying to squeeze it there.
And all I want you to do is pulse. You're going to inhale for 5 breathes and exhale for 5. Inhale for 5, exhale for 5. So your inhalations and your exhalations are 5 seconds each and you're making sure that your abdominals are staying engaged the whole time. If you have lower back issues just keep your feet flat. Do the same thing: lift from your sternum, tuck your chin under, inhale for 5, and then exhale for 5. One hundred times. And that's how you do the Pilates 100.
