Rocker with Open Legs
Rocker with open legs is a Pilates bodyweight exercise targeting the lower back and abdominal muscles. It involves rocking along the spine while holding the legs in a wide V-shape, developing spinal massage, core control, and hamstring flexibility.
How to do it
- Sit on the mat with your knees bent and feet lifted off the floor.
- Hold your ankles and straighten your legs out into a V-shape, balancing on your sit bones.
- Engage your core and round your lower back slightly.
- Inhale and rock backward, rolling onto your upper back while maintaining the V-shape.
- Exhale and rock back up to the balanced position.
- Repeat for the desired number of repetitions.
Form cues
- Keep your chin tucked toward your chest.
- Maintain a wide V-shape with your legs.
- Engage your core to prevent flopping.
- Keep the movement smooth and controlled.
- Balance on your sit bones at the top.
Breathing: Inhale as you rock backward, and exhale as you engage your core to return to the upright position.
Common mistakes
- Using momentum instead of core control, which reduces the effectiveness of the exercise.
- Tensing the neck, which can lead to unnecessary strain.
- Hitting the floor hard, which indicates a lack of spinal control.
- Rounding the upper back too much, which makes it difficult to return to the starting position.
Muscles worked
Primary: lower back. Secondary: abs, hip flexors, hamstrings.

Where should I feel this exercise?
You should feel it in your core muscles, specifically your abdominals, and a gentle stretch along your spine.
Is it okay to roll onto my neck?
No, you should only roll onto your upper back (shoulder blades). Avoid putting weight directly on your neck.
Can I do this on a hard floor?
It is best to use a yoga mat or a soft surface to protect your spine while rolling.
