Supine Bent-Knee Fall-Outs
Low-load rotational control exercise with maintenance of the neutral pelvic position. Challenges the abdominal obliques and the transversus to resist rotation — a natural progression after mastering heel slides in abdominal diastasis rehabilitation.
How to perform
- Starting position. Lie face-up with knees bent, feet flat on the floor, and arms relaxed at the sides.
- Step 2. Activate the transversus abdominis (drawing-in).
- Step 3. Maintaining activation, slowly let the right knee fall to the right side, with control — only as far as you can without letting the opposite pelvis lift off the floor.
- Step 4. Return the knee to the neutral position actively, using the core, over 3 seconds.
- Return. Alternate with the left knee. If the pelvis compensates (one side lifts), stop and resume the drawing-in — the range should be limited to what the core can control.
When not to perform
- Postpartum first week
- Recent hip surgery
- Acute sacroiliac pain
- Severe diastasis with visceral protrusion
- Acute pelvic pain
- Symptomatic rotational lumbar disc herniation

Transversus Abdominis Activation (Drawing-In)
Isolated motor activation of the transversus abdominis, the deep stabilizing muscle of the lumbar spine. The foundational motor-reeducation exercise — fundamental in core instability, sacroiliac dysfunction, and postpartum abdominal diastasis.

Pelvic Tilt
Gently activates the deep abdominal muscles through a pelvic tilt. Relieves low-back tension and retrains motor control of the deep stabilizers — one of the foundations of chronic mechanical low-back-pain rehabilitation.

Heel Slide with Transversus Activation
A low-load exercise that combines alternating heel slides with isolated activation of the transversus abdominis. Safe in the postpartum period and appropriate for early rehabilitation of abdominal diastasis — progresses the core without overloading the linea alba.
