Pilates Half Roll Back: How to Do It and Muscles Worked

Last updated

The Half Roll Back, sometimes called the half roll down pilates or roll back pilates, is a beginner contemporary mat exercise. It focuses on rolling halfway back from a sitting position and returning, creating gentle spinal flexion.

This movement primarily trains your rectus abdominis and transversus abdominis. As you control the roll, your obliques also work as supporting muscles to help keep your torso steady.

How to do the Half Roll Back

Sit tall on your mat with your knees bent and your feet flat on the floor in front of you. Reach your arms straight forward at shoulder height.

  1. Take a deep breath in to prepare your body.
  2. Nod your chin slightly and scoop your belly inward.
  3. Round your lower back to begin rolling backward off your sit bones.
  4. Continue rolling back until your arms are straight or you feel your abdominal muscles working hard.
  5. Pause for a moment in this halfway position.
  6. Use your abdominal muscles to pull yourself forward.
  7. Keep your spine rounded as you bring your shoulders over your hips.
  8. Stack your spine bone by bone to return to the tall starting position.
  • Breath. Teachers cue breathing differently, but a common pattern is to exhale as you roll back and inhale as you return to the top. You might also be taught to inhale as you roll back and exhale to come forward.
  • Where you feel it. You should feel deep work in your abdominal muscles as they control the movement. You should not feel pinching in your lower back or tension in your neck and shoulders.
  • How many. 5 to 8 slow and controlled repetitions

Common mistakes

  • Collapsing the chest. Keep your collarbones wide and avoid letting your shoulders hunch up to your ears.
  • Moving from the hips. Focus on creating spinal flexion by scooping your belly, rather than just leaning backward with a straight back.
  • Lifting the feet. Press your feet gently into the mat to help anchor your lower body.
  • Tensing the neck. Keep a soft space between your chin and your chest, looking softly forward rather than straining upward.
  • Going back too far. Only roll back halfway, stopping before your lower back touches the mat or you lose control of your core.

Make it easier or harder

Easier

  • Hold onto the backs of your thighs with your hands to help support your weight as you roll.
  • Roll up the edge of your mat behind your lower back to give you a physical stopping point and extra support.
  • Do a smaller range of motion, rolling back just a few inches before returning.

Harder

  • Reach your arms up by your ears as you roll back to increase the challenge.
  • Perform the exercise with your arms crossed over your chest to reduce the counterweight effect.

Who should be careful

  • If you have osteoporosis or low bone density, or a recent disc injury, ask your clinician whether repeated loaded forward bending of the spine suits you. Many bone health organizations recommend limiting it.
