Strive to maintain the normal lordosis of the lumbar spine during lifting.
Doing so assures that the angle of pull of the erector spinae create a posterior shear force on the lumbar vertebrae, thus reducing the high anterior shear forces that are associated with back injuries. You also avoid the repetitive strain on the posterior aspect of the lumbar discs that can result in herniation.
This may require that you reduce the depth of your squats or pull your deadlifts from a box until you’ve developed sufficient mobility in your hips.
