The Miles Circuit is a prenatal exercise routine developed by childbirth educator Gail Tully of SpinningBabies.com, designed to promote optimal fetal positioning during late pregnancy. It involves a sequence of three specific body positions, each held for 30 minutes, to improve pelvic space and encourage the baby to rotate into a head-down, anterior-facing position for labor. This routine matters for expectant parents seeking natural ways to support birth outcomes, potentially reducing interventions like cesarean sections. Always consult a healthcare provider before starting, as individual circumstances vary.
What Is the Miles Circuit?
The Miles Circuit targets maternal posture and ligament balance to create more room in the pelvis. It consists of:
- Hands-and-knees position(30 minutes): Kneel on a soft surface with hips over knees and shoulders over hands, keeping the back flat. This opens the upper pelvis and relieves upper body pressure.
- Right-side lying position(30 minutes): Lie on your right side with the right leg straight and left leg bent at 90 degrees, supported by pillows. A peanut ball or pillow between the knees enhances hip opening.
- Left-side lying position(30 minutes): Mirror the previous position on the left side, with left leg straight and right leg bent.
Total time commitment: 90 minutes. These durations are measured in minutes, equivalent to 1,800 seconds or 0.5 hours per position—precise timing supports consistency.
Does the Miles Circuit Have to Be Done in Order?
Yes, the Miles Circuit is most effective when performed in the specified order. The sequence is intentional:
- The hands-and-knees position first loosens the upper uterus and broad ligament.
- Transitioning to the right side addresses common right-rotation fetal patterns.
- Ending on the left side balances the pelvis and encourages left-occiput anterior positioning.
Disrupting the order may reduce cumulative benefits, as each step prepares the body for the next. Spinning Babies recommends following the progression, though slight adjustments (e.g., shortening times) can be made under professional guidance. Flexibility exists for comfort, but the core principle relies on this progression.
Step-by-Step Guide to Performing the Miles Circuit
1.Prepare your space: Use a firm mattress, pillows, peanut ball, and timer. Ensure a quiet environment.
2.Start with hands-and-knees: Set a timer for 30 minutes (or convert to 1,800 seconds if tracking precisely). Breathe deeply and relax the jaw.
3.Move to right-side lying: Without standing, roll directly into position. Time another 30 minutes. Focus on hip opening.

5.Finish gently: Sit up slowly, hydrate, and note any sensations.
Repeat daily or every other day from 37 weeks, or as advised.
Practical Applications and Common Mistakes
In real-world use, the Miles Circuit applies to home-based prenatal care, complementing midwifery or doula support. Engineers and researchers tracking maternal health metrics appreciate its structured timing, where unit accuracy matters—e.g., converting 90 total minutes to 1.5 hours for scheduling.
Common pitfalls:
- Ignoring sequence: Skipping order diminishes ligament release synergy.
- Inaccurate timing: Use a reliable timer; avoid estimating to ensure full benefits.
- Poor support: Insufficient pillows lead to strain—measure pillow heights (typically 12–18 inches) for alignment.
- Overdoing it: Stick to recommended durations; convert units correctly if adapting (30 min = 0.5 hr).
Key Takeaways
The Miles Circuit works best when done in order to leverage sequential physiological effects on pelvic alignment and fetal positioning. While not mandatory to the letter, adhering to the progression maximizes results.
