Down Stretch: How to Do It and Muscles Worked

Last updated

The Down Stretch is an intermediate Reformer exercise that focuses on kneeling extension while pressing the carriage back. Often called the down stretch reformer, it challenges your ability to maintain a long, supported arch in your back as you move.

This movement primarily targets your spinal extensors, triceps, and latissimus dorsi. As you press the carriage away, you will also experience a lengthening stretch through your supporting muscles, the hip flexors. It requires focus and control to keep your spine supported throughout the extension.

How to do the Down Stretch

Kneel on the Reformer carriage facing the footbar with your knees against the shoulder blocks and your hands resting lightly on the footbar.

  1. Press your hips forward and lift your chest to create a long, supported arch in your spine.
  2. Keep your arms straight and your shoulders down away from your ears.
  3. Press the carriage back by using your latissimus dorsi and triceps, maintaining your spinal extension.
  4. Keep your gaze slightly lifted to follow the natural curve of your upper back.
  5. Pull the carriage back to the starting position without losing the extension in your spine.
  6. Pause briefly at the stopper before beginning the next repetition.
  • Breath. Teachers cue the breath differently, but you will often hear an inhale as you press the carriage back and an exhale as you return. Some instructors prefer the opposite, so follow the pattern that helps you maintain control.
  • Where you feel it. You should feel your spinal extensors, triceps, and latissimus dorsi working to support the movement, along with a stretch in your hip flexors. You should not feel sharp pinching or compression in your lower back.
  • How many. 3 to 5 slow, controlled repetitions

Common mistakes

  • Sinking into the lower back. Focus on lifting your chest and lengthening your spine rather than just bending backward. Keep your abdominal muscles engaged to support your lower back.
  • Bending the elbows. Keep your arms straight to effectively engage your triceps and latissimus dorsi. Press through your palms without locking your elbow joints.
  • Dropping the head. Keep your neck in line with the rest of your spine. Your gaze should be forward and slightly up, following the curve of your upper back.
  • Shrugging the shoulders. Draw your shoulders down and away from your ears. This helps activate your latissimus dorsi and keeps tension out of your neck.
  • Losing the hip stretch. Keep your hips pressed forward gently as you move the carriage. If you let your hips drop back toward your heels, you will lose the lengthening in your hip flexors.

Make it easier or harder

Easier

  • Practice kneeling spinal extension on the mat without the moving carriage.
  • Reduce the range of motion by pressing the carriage back only halfway.
  • Perform the movement with a neutral spine instead of full extension to build upper body strength first.

Harder

  • Increase the spring resistance to challenge your triceps and latissimus dorsi more.
  • Hold the extended carriage position for three seconds before returning to the stopper.

Who should be careful

  • Back extension can irritate some conditions, such as spinal stenosis or spondylolisthesis. Keep the lift small or skip it if it brings on back or leg symptoms.
  • Kneeling can be uncomfortable with knee pain; use extra padding or choose a version that keeps you off the knees.
  • Weight-bearing through the hands can aggravate wrist, hand or shoulder pain. Fists, forearms or a raised surface can reduce the load.
  • Reformer springs and the moving carriage add load and instability. Learn it with a qualified instructor, who can set the springs for your body and goals.
