The straight leg deadlift (SLDL), sometimes referred to as the stiff-legged deadlift, is a fundamental resistance training exercise that specifically targets the posterior chain, including the hamstrings, glutes, erector spinae, and supporting core musculature. Unlike the conventional deadlift, the SLDL emphasizes a minimal knee bend and a greater hip hinge pattern, creating unique mechanical demands that yield a range of benefits backed by scientific evidence.

This article explores five major benefits of the straight leg deadlift, with a focus on physiological adaptations, performance improvements, and injury prevention. Each claim is supported by peer-reviewed research and biomechanical analysis, ensuring the information is both accurate and practical for athletes, strength coaches, and
