CoreBW
A dynamic side plank variant where the hips lower toward the floor and lift back up repeatedly, adding a concentric/eccentric loading component to the isometric anti-lateral flexion demand.
Demo: Eccentric Physio
Sets
3
Reps
10-12 per side
Rest
45s
Contraindications
Shoulder pain — regress hold time.Setup
Set up in a standard side plank position, hips elevated in line with the body.
Execution
- 1From the top side plank position, lower the hips slowly toward the floor without fully resting
- 2Stop just before the hips touch down
- 3Drive the hips back up to the straight-line position
- 4Keep the body from rotating forward or backward during the drop
- 5Repeat for reps, then switch sides
Key cues
- Lower with control, don't just drop
- Drive back up through the obliques
- No rotation forward or back during the dip
- Small controlled range, not a big bounce
Common faults
- Dropping too fast and losing control
- Body rotating forward during the descent
- Not achieving full hip extension at the top
- Using momentum instead of oblique strength to rise
Tweaks
- Reduce range of motion as a regression
- Add a pause at the bottom for more time under tension
- Progress to elevated feet for more difficulty
