Roll only as far as your back stays flat — the abs resist the arch, that's the whole exercise.

No-Fly Zone
under 5 reps (rolling out past your control just arches and strains the lower back)
Programming
Late
Hard anti-extension under stretch — a finisher; form fails fast when fatigued, so keep reps strict.
Model — Double
Fallback model — Density
Progress ROM first (roll further while keeping a flat back), then reps, then move toward standing rollouts.
Full body
If it hurts
Pain is information, not a challenge to push through. Stop the set if pain is sharp, worsening, or changes how you move. These are exercise-selection options, not medical diagnosis or rehabilitation advice.
Work down this list in order. Stop at the first change that removes the pain.
Step 1
Knees vs standing; rollout distance; incline (roll up a ramp) to scale.
Step 2
Pause at full extension; slow eccentric out; partial ROM if the lower back arches.
Step 3
Plank/long-lever plank, barbell rollout, or stir-the-pot on a ball.
Substitutions
Plank/long-lever plank, barbell rollout, or stir-the-pot on a ball.
Compare all core optionsThe Evidence
Builds powerful anti-extension core strength under stretch. NOT a beginner move — a sagging back makes it a lower-back exercise.
