Low Back Pain CoachShort Answers to Common Back Extension Questions
The main guides don't cover every small question. This page answers the ones that kept coming up: hands, neck position, numb feet, and missed weeks.
The program is the loaded 45-degree back-extension progression, 2 or 3 days a week, paced by the next morning. If there is no bench yet, floor work comes first, and only until you have one.
Setup and form
Where do my hands go?
Crossed on your chest. With your hands behind your head the lever gets longer, and it is easy to start pulling on your neck. When you hold a plate in Stage 4, it sits on your chest, where your hands already were.
Where do I look?
At the floor, a foot or two in front of the bench. Keep your neck long. Looking at the wall in front of you is how people crank the top of the rep into an arch, and the arch is where my low back used to complain mid-set. Keep your neck in line with your back through the rep.
Should I feel this in my glutes or my low back?
Both. The work sits in the muscle beside the spine and in the hips. A pinch right at the belt line during the rep can mean too much range or arching past the top, so shorten the range and come up only until your back has straightened. A sharp or electric feeling, or anything running into a leg, ends the set, and pain in the legs means stopping the extension work.
One side does all the work. What do I change?
Common if you sat at a desk for years, which is how mine started. Slow the rep down, check that your hips are centered on the pad and both ankles sit evenly in the rollers, and add no load until both sides show up. Leg or foot weakness that is getting worse, or new pain, tingling, numbness or weakness in both legs, means go to emergency care now. Other new weakness or numbness in one leg or foot means see a clinician today. Pain running into a leg means stop the extension work. Sharp pain that stays on one side is a question for a clinician.
My feet go numb in the ankle rollers. What do I do?
Stop the set and step off. The red flags come first: new pain, tingling, numbness or weakness in both legs, or leg or foot weakness that is getting worse, means go to emergency care now, and other new weakness or numbness in one leg or foot means a clinician today. If none of those apply, loosen the rollers a notch and check that your hips sit on the edge of the pad, so your weight rests on the pad rather than hanging from your ankles. Socks help on cheap rollers. If the numbness keeps coming back with a good setup, see a clinician.
Do I need a warm-up?
For me, the first hold is the warm-up. I used to foam-roll for fifteen minutes and then wonder why the session felt like a second workout. Now I walk to the bench and start the first set. If a clinician gave you a warm-up, keep it.
Pacing and schedule
The next morning is worse. Do I train?
Log it and take the session the rule gives you. Any log above your baseline cuts the next session back: about 30% off holds and full reps, a rep and 10% of range off partials, 5 lb off the plate (down to 5 lb, then reps). If the pain keeps climbing through the day, or you are walking guarded, skip the session, walk, and use the flare-up plan. I used to treat any leftover ache as a reason to rest for a week. Go to emergency care now for new numbness, tingling or change in feeling in the saddle area (groin, inner thighs, genitals or anus), new changes in sexual function, new bladder or bowel changes, new pain, tingling, numbness or weakness in both legs, leg or foot weakness that is getting worse, or back pain after a recent serious accident. See a clinician today for other new weakness or numbness in one leg or foot, fever or chills alongside the back pain, new pain after a recent smaller fall or knock, unexplained weight loss or a history of cancer, pain that is rapidly getting worse, or pain that is constant at rest and worse at night, not tied to movement. Use urgent care if you cannot get an appointment today. Check the red-flag list.
Can I squat or deadlift on the same day?
If those lifts are already in your week and the next morning still holds near baseline, yes. I have lifted since my teens and I kept squatting through this. I did not add a new heavy hinge the same week I jumped a stage on the bench. In a week when the barbell work goes up, keep the bench session the same. The return-to-lifting guide covers loaded lifting after pain.
What if I miss a week?
Come back easier than you left, and do not stack the missed sessions on Saturday. After 7 or more days off, the app eases the next session whatever the logs say. After my first daughter was born I vanished for weeks, blamed the hospital bed, and jumped back in angry. New-parent sleep and stress had more to do with that flare than the mattress, the same pattern that started this at a desk job in my early twenties: no accident, loud week, loud back. Restart light and let the next-morning logs bring the dose back up.
Other exercises and equipment
I already do bird-dogs. Do I add them on rest days?
I would not. I went through PT, chiro, needling, and acupuncture, then a long stretch of bird-dogs, dead bugs, and the McGill Big 3. They helped until they stopped helping, and the bench work took their place for me. Extra work on rest days also blurs the next-morning reading. If a clinician gave you bird-dogs, ask how they fit with the bench. The guide on why PT exercises stop helping covers the plateau.
Is the floor version a real start?
It is a start, and it lasts only until you have a bench. A floor round is a prone hold, 6 bird-dogs, and 8 glute bridges. Tap “I have a 45° bench now” on Today and the next session is Stage 1. If you said in the setup questions that you have a bench, the app moves you on by itself when each of your last three floor training days includes a prone hold of about 30 seconds (or 90 seconds of holding in total; partial sessions do not count), your pain is logged on at least 3 of the past 7 days with none above baseline or in your legs, and your next-morning check-ins allow a step up. If you get a bench sooner, move sooner. The no-bench page has the details.
My gym only has the vertical Roman chair. Can I use it?
Find a 45-degree bench. This program is not written for the vertical 90-degree chair, and its stages and numbers do not carry over to it. Try another gym, or look at a home bench in the buying guide. The floor session covers the gap until then. The 45 vs 90 guide shows how to tell the two apart.
