A cranky lower back is a routing problem, not a stop sign.

Most backs that are sore, stiff, or generally reactive will tolerate far more than their owners expect — as long as you change the direction the load is coming from rather than how hard you’re working. The instinct is to stop everything for a fortnight. That’s the one intervention with a dependable downside.

First, the things that aren’t training problems

Some symptoms mean the conversation isn’t with me. Stop and call a clinician today if you have any of these.

• Any loss of bladder or bowel control, or numbness through the saddle area. That’s an emergency department, not an appointment.

• Weakness in a leg that’s getting worse — a foot that drops, a calf that won’t raise you onto your toes.

• Back pain that started after a fall, a crash, or any real impact.

• Pain that wakes you every night regardless of position, or that arrives alongside fever or weight loss you didn’t plan.

None of that is common. Everything below assumes none of it applies to you.

Find the direction it doesn’t like

Backs have preferences, and yours will tell you what its one is inside a week. Notice which of these makes it worse over the following hour.

• Sitting for thirty minutes, or a long drive.

• Standing still in one place, or walking downhill.

• Bending forward to tie your shoes, particularly first thing in the morning.

• Arching back to reach something on a high shelf.

If sitting and morning bending are the aggravators, your back is flexion-sensitive — that’s the common one. If standing and arching are worse, it’s extension-sensitive. That single answer determines nearly everything about the next fortnight, because it tells you which loaded positions to route around and which ones you can lean into.

What I actually change

For a flexion-sensitive back, here’s the two-week version.

• Axial load comes off. Back squat becomes a heel-elevated goblet squat or a belt squat; the deadlift comes out entirely for now.

• The hinge stays, lightly loaded. 45-degree back extensions at 2×12 @6 RPE · 90s · 20X1, driven by the hips, with no rounding at the top.

• Unilateral work goes up. Split squats, step-ups and single-leg RDLs at loads that are meaningful for your legs and negligible for your spine.

• Everything above the waist continues unchanged. There’s no reason your bench press should suffer because your back is annoyed.

• Walk twenty to thirty minutes a day, every day. It’s the single most reliable item on this list and the one people skip.

• Nothing heavy inside the first hour after waking. Discs are at their most hydrated overnight and least tolerant of loaded flexion first thing.

Coming back

Once you’ve had three consecutive days with no symptoms at rest, reintroduce the loaded pattern at roughly half what you were using, one session a week, with an explicit rule for what’s allowed: a dull two-out-of-ten sensation during the set that’s gone within an hour, and nothing worse the next morning. Clear both tests and you add ten percent next week. Fail either and you drop back one step and hold there. Most people are back at their old numbers in four to six weeks — slower than they’d like, and far quicker than the total-rest route.

The reason total rest performs badly is that the back gets weaker and more sensitive at the same time. Then the first session back reproduces the symptom, and you learn the wrong lesson: that lifting hurt you. It didn’t. The three weeks of doing nothing did.

RANGE is built entirely on this logic — five short sessions a week, no axial load, unglamorous by design. It’s the thing I most often run alongside somebody’s return to the barbell, and it’s usually the last program they expected to need.
