Tight hamstrings don’t just feel uncomfortable, they block your hips from moving. When that happens in a deadlift or hinge, your spine flexes to steal the range. Flexion isn’t bad, but loaded flexion without control is what overloads the L4/L5 and L5/S1 discs. 👉 The fix isn’t endless stretching. It’s getting long and strong: 1️⃣ Jefferson Curls. Build hamstring length and spine control in flexion. 2️⃣ Romanian Deadlifts. Hinge deep while keeping the spine neutral. 3️⃣ Back Extensions with Reach
