Screening a Postpartum Client Who Wants Planks
Nadia is 34, 10 months postpartum after her second cesarean birth. She has been cleared for exercise and wants visible abs in 12 weeks. At intake she reports leaking a small amount of urine when she jumps or sneezes and sees a ridge along her midline when she does a crunch. Her self-measured inter-rectus distance is about 2.5 finger widths at the umbilicus and 1.5 finger widths 4 cm above. She has no pain, no bulging at the incision, and no heavy bleeding. She can commit to three 30-minute sessions per week at home with a mat, resistance band, and chair. She asks to start with planks and weighted Russian twists because those are in a program she found online. She is also training for a 5K in 8 weeks.
1. What does the screening information suggest, and what additional assessments would you perform before loading her core? Explain the reasoning for each.
Read the worked answer
Interpretation: the combination of urine leakage with impact, visible doming with a crunch, and a 2.5-finger inter-rectus distance at the umbilicus suggests impaired load transfer through the linea alba and pelvic floor, not simply weak abs. She is 10 months postpartum and cleared, but clearance does not equal readiness for high-load flexion or rotation. The 5K goal adds impact demands that can provoke leakage.
Additional assessments:
- Breathing: check whether she can inhale into the ribs and exhale without chest lift. This screens diaphragm and pelvic-floor coordination.
- Pelvic-floor screen: can she contract and relax? Leakage with jumping suggests a coordination or support issue; do not assume it is just weakness.
- Trunk endurance: side plank from knees, dead bug, and light loaded carry, watching for doming and breath holding.
- Hip and thoracic mobility: limited hip extension or thoracic extension can drive lumbar compensation.
- Symptom response: track leakage, doming, and next-day symptoms.
Reasoning: the screen should identify whether the problem is load management, breathing and coordination, or tissue capacity. A finger-width measurement alone does not determine whether planks are safe; the response to load and the ability to manage pressure matter more.
2. How would you respond to her request to begin planks and weighted Russian twists? Include modifications, progression criteria, and referral triggers.

Response: do not start weighted Russian twists; they combine flexion, rotation, and load, which is a high-demand pressure strategy for her. A front plank may be appropriate only after she can breathe and keep the rib-pelvis relationship; start with a knee plank or incline plank and watch for doming.
Initial block:
- 90/90 breathing, 2 x 5 breaths.
- Dead bug with one leg only, 2 x 6 per side, exhaling on extension.
- Supported side plank from knees, 2 x 15 s per side, with a cushion or chair.
- Light suitcase carry, 2 x 20 m per side, focusing on no lean and easy breathing.
Cue: exhale as you reach, keep the ribs stacked over the pelvis, and stop before the midline ridges.
Progression criteria: no leakage, no doming, no breath holding, and no next-day heaviness for two consecutive sessions; then increase lever length or time before load. For the 5K, add impact gradually and monitor leakage.
Referral triggers: pain, heaviness or bulging at the incision, worsening leakage, doming that does not resolve with cueing, or any sensation of pelvic-floor dropping. Refer to a pelvic-health physiotherapist; do not diagnose diastasis recti yourself.
