The "Cat Back" Deadlift

The most common cause of lower back pain is lifting with a rounded lumbar spine(flexion).

When your spine rounds, the load shifts from the muscles(Erectors) to the passive structures(Discs and Ligaments).This creates massive shear force.One bad rep can bulge a disc.

The Fix is NOT "Squatting" the Weight.

Many lifters try to fix this by dropping their hips too low and trying to "Squat" the bar up.This doesn't work. Your hips will shoot up first, and you will end up rounding your back anyway. The Deadlift is a Hinge, not a Squat.

The Protection Checklist

  1. 360 - Degree Bracing: Take a huge breath into your belly, not your chest.Imagine wearing a belt and trying to break it with your stomach.Brace your core like you are about to be punched.This creates Intra - Abdominal Pressure(IAP) that acts like an airbag for your spine.
  2. Engage the Lats: This is the most forgotten cue.Imagine you have oranges in your armpits and you are trying to make orange juice.Squeeze your arms against your sides.The Lats(Latissimus Dorsi) are massive back muscles that span the spine.When they are tight, the spine cannot round.
  3. Pull the Slack Out: DO NOT jerk the bar off the floor.Before you lift, pull up gently on the bar until you hear the "click" of the plates hitting the top of the sleeve.Get tight. Then drive.
  4. Push the Floor Away: Think "Leg Press the floor away." Do not think "Pull the bar up."

Rehab & Prevention

If your back hurts, stop deadlifting for a week.Use this time to do:

  • Bird Dogs & Planks: Re - teach your core to stabilize the spine.
  • Glute Bridges: Wake up your glutes.If your glutes are weak, your lower back takes over.
  • Reverse Hyperextensions: If you access to this machine, use it.It decompresses the spine while strengthening the lower back.

The Verdict: The Deadlift is actually one of the best exercises for preventing back pain, if done correctly.A strong back is a healthy back.

Sumo vs.Conventional

If you have long femurs(thigh bones) and a short torso, Conventional Deadlifts will always put more shear force on your spine because you have to lean over more.

Try Sumo Deadlift .

The wide stance allows you to keep your torso upright.This drastically reduces lumbar load.It is not cheating; it is biomechanics.If Conventional hurts, switch to Sumo.
