The Hundred: How-to, Benefits & Variations
The hundred is a Pilates core exercise: lie back, lift head and legs, pump arms 100 times (5 inhale, 5 exhale). Builds core endurance, breath control, and abdominal heat in under two minutes.
The Hundred: How-to, Benefits & Variations
Joseph Pilates invented this exercise in the 1920s and named it after the hundred arm pumps you perform during a single set. A hundred years later, it is still the opening exercise in most classical Pilates classes. Not because of tradition. Because nothing else warms up the entire core system this quickly.
You lie on your back, lift your head and shoulders off the mat, extend your legs to a challenging angle, and pump your arms up and down with small, rapid movements. You inhale for five pumps. Exhale for five pumps. Ten breath cycles. One hundred pumps. Your core is engaged the entire time.
The hundred is a breathing exercise disguised as a core exercise. The arm pumping forces your diaphragm and abdominal wall to coordinate under sustained contraction. Your lungs expand and contract while your abs hold an isometric position. That dual demand is what makes it uniquely effective and uniquely uncomfortable.

How to Do The Hundred
Set up in the starting position for the hundred. Feet hip-width apart (or as the exercise requires). Engage your core before initiating any movement.
Begin the movement with control. Lianna Brice cues: "Tuck your chin to your chest... little presses down with your arms."
Complete the full range of motion. "As we're pushing the legs forward, and then exhale. Back in."
Return to the starting position with control. Back is pulling down, centering our body.
Amelia Jane adds: "Curl up, palms to face down. You're gonna pulse down."

Why this matters in perimenopause
