Neutral Spine? How to Deadlift and Squat Without Hurting Your Back
The human spine is a robust and durable structure. It has the ability to flex, extend, and rotate through incredible ranges of motion while also able to lock down allowing the transfer of force between the lower and upper limbs so we can jump, run, throw, swing or lift heavy things.
While both motion and force transfer are normal healthy things a spine should and can do, combining motion with loading can be a problem.
The solution? Move weights, land, or create power with a spine that is in a neutral alignment.
Neutral, so keep your back straight?
Straight is close, but it’s not technically correct.
Neutral can be defined as “the normal curvature of the spine present in a standing posture”. A neutral spine has alternating sections of lordotic (lumbar and cervical) and kyphotic (Thoracic and sacral) curves.
These subtle curves form an S shape allowing even distribution of load through the intervertebral discs, placing a balanced compressive force on them.
When the spine is out of neutral, compressive force that is applied pushes unevenly on the discs, stressing the annulus. This is a big problem for the discs in flexion as the spine has no supporting posterior ligament means when a compressive force is applied to a flexed spine. The spine has an inbuilt anterior ligament (a hangover from our evolution from quadruped) which keeps the discs from bulging forwards, as a result, discs cope well under extension (although the vertebral joints themselves don’t fare so well). but are pushed backward stretching and stressing the rear annulus wall.
This presents two key problems:
- We tend to outlive our discs – Discs are the shock absorbing jelly between the vertebrae, over the course of a lifetime, they become worn down gradually and are very slow to heal and regenerate (if they regenerate at all). The discs of a twenty-something-year-old are flexible and pliable, almost like camembert cheese, as we age these discs become brittle fragile and by middle adulthood are more parmesan than camembert.
Herniated discs don’t fix easily – Once a disc is bulging (prolapsed, herniated) it doesn’t heal itself, this irreparable damage can be surgically fixed (with great difficulty, and no guarantee of success). Herniated discs are pretty common in middle and older populations and can often be asymptomatic, but that’s not a gamble I would want to be taking
Here at Core Advantage, we have a golden rule,”Get as low as you can, whilst maintaining neutral.”
We use seats to control depth on squats,
and we use blocks to control the depth on our Corelift, deadlift, and Olympic lifting variations, which we adjust according to individual’s mobility and control.
That doesn’t mean that we’re afraid of flexion, or any motion for that matter, but what we do is we separate them out, so we do our heavy lifting in a neutral spine alignment, and then if we’re going to add any flexion to the spine, we do it when the spine is unloaded in something that we call a ROM squat.
ROM Squats allow you to chase excellent range without the loads on the spine, improving the ability to get down into a low athletic stance to help us move better laterally.
How to Minimise Disc Stress
Regular breaks from the desk – Sitting puts the spine in a flexed & compressed position with our core muscles. Take calls standing, have meetings on the go, get a standing desk. If you have to sit, set timers for standing breaks, every 30-45 minutes is ideal to minimise muscular creep. These anti-desk workouts are a good start
- Always pick things up with a neutral spine – Learn proper lifting technique, bend the knees, hinge over from the hips and protect your spine.
- Strengthen the glutes – Weak glutes leads to an overload on the lower back. Strong active glutes will help your sporting and gym performance and can be a lead domino in any chronic back pain/tightness.
Consider giving the deadlifts and deep squats a rest – You are most likely in the majority of the population who cannot deadlift from the floor or squat below parallel while maintaining a neutral spinal alignment. Block or rack pulls and shortening up the range of your squat is a great way of reducing the stress to your discs while continuing to get most of the benefit for lower body training effect.
