best stretches and recovery tools for persistent lower back soreness after heavy deadlifts and squats
Summary
Lower back soreness after heavy lifting is often caused by compressed spinal joints, tight hip flexors pulling on the pelvis, or overactive erector muscles. While some soreness is normal, persistent pain usually indicates that your body is struggling to recover from the high mechanical load of squats and deadlifts.
Most likely causes
- Lumbar Compression: Heavy axial loading (weight on the spine) can temporarily compress the intervertebral discs and joints.
- Hip Flexor/Psoas Tightness: Overactive hip muscles can pull the pelvis into an "anterior tilt," putting constant strain on the low back.
- Gluteal Amnesia: If your glutes "shut off" during recovery, the lower back muscles (erectors) take over the workload of staying upright.
- Delayed Onset Muscle Soreness (DOMS): Structural micro-tears in the muscle fibers following high-intensity training.
