CoreBW
Elbows are walked forward of the shoulders, lengthening the lever arm between the base of support and the hips. This dramatically increases the anti-extension demand on the anterior core compared to a standard plank.

Sets

Reps
15-30 sec hold
Rest
45s
Contraindications
Skip if standard plank still breaks down in under 30 seconds — build base strength first.Setup
From a forearm plank, walk elbows forward several inches so they sit ahead of the shoulders, near forehead height.
Execution
- 1Posteriorly tilt the pelvis and brace the abs hard
- 2Keep a dead straight line from shoulders to heels
- 3Resist the urge to let the hips sag as the lever lengthens
- 4Breathe in controlled 3-second in / 5-second out cycles
- 5Walk elbows back in if form breaks down
Key cues
- Elbows ahead of your eyes, not under your shoulders
- Fight the sag the whole time
- Broomstick from head to tailbone
- Longer lever, same rigid line
Common faults
- Letting the low back sag as the lever increases
- Ribs flaring up and out
- Walking elbows too far forward too soon
- Losing breathing control and gripping tension in the neck
Tweaks
- Add rocking forward/back for dynamic tension
- Combine with single-leg lift
- Progress to feet elevated long-lever plank
