The Pilates Hundred is a classical Pilates mat exercise. It is a fundamental exercise that I recommend practicing daily to increase your core strength. The Hundred consists of pumping your arms 100 times while your legs are extended, your core is activated, and taking inhale / exhale breaths. The Pilates Hundred is fully customizable to fit your needs and skill level. You can learn how to do The Pilates Hundred exercise by reading my how-to steps below. I have also included a supplemental video demonstration so you can customize the exercise with beginner, intermediate, advanced, or expert leg progressions!
