Hundred

I want you to feel a steady, humming engagement across your entire core as you pulse your arms by your sides. Good reps feel like controlled, rhythmic energy—deep abdominal bracing without breath-holding, shoulders anchored away from your ears. You’ll notice a gentle heat building in your midsection and a light, focused fatigue in your arms. Stay grounded through your pelvis, let your breath drive the tempo, and embrace the burn as a sign of precise, sustained activation.
Steps
- 1
Lie flat on your back with your legs extended straight and your arms resting by your sides.
- 2
Draw your navel toward your spine and gently press your lower back into the mat to engage your core.
- 3
Lift your head, neck, and shoulder blades off the floor while keeping your gaze fixed on your navel.
- 4
Raise both legs to a 45-degree angle, maintaining a straight line from hips to toes, or bend your knees to a tabletop position if needed.
- 5
Extend your arms straight out alongside your torso, hovering them just above the floor.
- 6
Pump your arms up and down in a steady, short range of motion while inhaling for five counts and exhaling for five counts.
- 7
Continue the rhythmic arm pumps and coordinated breathing until you complete ten full breath cycles.
- 8
Lower your head and shoulders back to the mat, then slowly bring your legs down to rest completely.
If you're new to this
Focus on maintaining a neutral spine by gently pressing your tailbone toward the floor before lifting your head. If your lower back arches or lifts off the mat, bend your knees into a tabletop position to reduce the lever arm and protect your lumbar spine. You should feel a deep, sustained contraction across your entire abdominal wall, not a sharp pinch in your neck or lower back. Stop immediately if you experience neck strain or dizziness, and rest your head down to reset. A common compensation is shrugging your shoulders toward your ears or pumping your arms from the elbows instead of the shoulders. Keep your shoulders relaxed, chest open, and movements controlled. Remember, the Hundred is about breath control and core stability, not speed. Start with fewer breath cycles and build your endurance gradually. Consistency will teach your nervous system to recruit your deep stabilizers efficiently without unnecessary tension.
Common mistakes
Most practitioners rush the arm pumps, sacrificing control and turning the movement into frantic flailing rather than a deliberate core exercise. Another frequent error is holding the breath or forcing shallow chest breathing, which defeats the entire purpose of the rhythmic five-count inhale and exhale. Many also lift their head too aggressively, jamming the cervical spine and creating neck tension instead of relying on the abdominals to initiate the curl. Finally, allowing the legs to drift too low or sagging the hips creates a pronounced lower back arch, shifting the load away from the core and onto the lumbar joints. Prioritize a stable pelvis, steady breathing, and smooth shoulder-driven arm motion over hitting the exact count quickly.
