Spine and Lower-Back Care for Squats and Deadlifts

Published October 23, 2026 · Last reviewed October 23, 2026

What the evidence says about the lower back in lifting

A review of injuries across weight-training sports found that the shoulder, lower back, knee, elbow and wrist or hand were generally the most commonly injured sites, and that strains, tendinitis and sprains were the most common types. It also found few differences in injury outcomes by age, sex or competitive standard, and noted that only four of the 20 studies were prospective (Keogh and Winwood 2017). The lower back is a common site, not an inevitable one.

AAOS names muscle soreness from unaccustomed activity as a common cause of low back pain, with overstretched or injured muscle and ligament fibres that usually settle within a few days, while disk problems can cause longer-lasting pain. On the bar, how much pressure you create inside the trunk changes by lift: a systematic review of 16 studies found the highest intra-abdominal pressure in squats (over 200 mmHg), 161 to 176 mmHg in deadlifts, slide rows and leg presses, and the lowest in the bench press (79 ± 44 mmHg) (Blazek et al. 2019). For BFor C Full protocol:

Action

Build squat and deadlift load in small, logged steps, and spend your first weeks on the lighter version of the pattern (goblet, trap-bar, rack pull from knee height).

Why it helps

The pressure review concluded that untrained people should avoid heavy squats, deadlifts and similar lifts until they have adapted to high loads. AAOS lists soreness from unaccustomed activity as a common cause of low back pain.

Verification

Your back rating the next morning is within 1 point of your pre-session rating, and the log shows one change per week.

Action

Set your position and brace before the rep starts: feet planted, bar close, a full breath, then hold the same torso shape through the lift.

Why it helps

A review concluded that the Valsalva maneuver reliably raises intra-abdominal pressure, which may help spine stability and trunk rigidity in resistance exercise, and that its health risks remain unconfirmed (Hackett and Chow 2013). The pressure review suggested the bench press and slide row for beginners and for people with hypertension (Blazek et al. 2019), so ask a clinician about breath-holding lifts if you have a blood pressure or heart condition.

Verification

The torso looks the same on the last rep as on the first, and you finish the set feeling stable rather than strained.

Action

End the set when your position changes, not when the bar stops. Stop the exercise if back pain builds.

Why it helps

Mass General Brigham advises resting if pain persists when you return to exercise and warns that pushing through can turn a minor strain into a real injury. No study cited here sets a rep or RPE cut-off for protecting the back, so this rule is a coaching convention.

Verification

Your set ends with a clean last rep and no new back tightness that evening.

Action

Stay active on a sore back within comfort, with walking and gentle movement, rather than resting in bed.

Why it helps

The NHS advises staying active and continuing daily activities, avoiding long periods in bed, and notes that back pain often improves within a few weeks. AAOS says exercise to restore motion and strength can help.

Verification

Stiffness eases with walking, and each day is no worse than the one before.

The 15-minute back check

1. Walk or cycle easily for 5 to 10 minutes before you touch the bar.
2. Do two or three ramp-up sets of the lift, with the first at a weight you could do all day.
3. Set your position before each rep: feet planted, bar close, a full breath, and a brace you can hold the whole rep.
4. End a set when the position of your torso on the last rep looks different from the first rep, and stop the exercise if back pain builds.
5. Walk for a few minutes afterwards and rate your back from 0 to 10 that evening and the next morning.
6. At the next session, compare the ratings with the last one before you decide the load.

Profile variants

For A Beginner. Keep loads conservative and positions stable. Learn the pattern with a light load first, and see the first six months guide.

For B Intermediate. Do not add both a heavier deadlift and a new squat day in the same week. Let the 0 to 10 back rating decide whether you repeat or progress.

For C Advanced. Heavy singles and doubles at high intra-abdominal pressure carry the highest trunk demand. Space them, and use the back rating plus the log to catch a trend before it becomes a flare.

For D Coach. Teach a repeatable set-up routine and give the stop-the-set rule as part of the session plan. Ask every client about blood pressure and heart conditions before teaching breath-holding.

For E Rehab-focused. Stay inside your clinician’s clearance, and let them decide which lifts return and when. See returning to lifting after injury.

How it works

Both lifts load the trunk heavily. Pressure inside the abdomen is shaped by body position and external load, which is why the squat sits at the top of the range and the bench press at the bottom (Blazek et al. 2019). Holding the breath against a closed throat raises that pressure further and may assist trunk rigidity (Hackett and Chow 2013). Whether any particular breathing or bracing pattern prevents back injury in lifters is Not reported in the sources cited here.

Worked example

Pressure demand differs by lift. Using the review’s figures, squat pressure of over 200 mmHg is 200 ÷ 79 = about 2.5 times the bench-press average of 79 mmHg. That is why a lifter returning from a back flare might rebuild the pressing and rowing work first. The figures are averages from different studies with different loads, so they show a pattern, not a safe limit.

A back-pain log: Monday’s deadlift session leaves pain limiting your function on Tuesday, Wednesday and Thursday, which is 3 days. If Friday is a fourth day, pain has limited function for more than 3 days, the point at which Mass General Brigham advises seeing a clinician.
