Hamstrings Exercises

Hamstrings run down the back of your thigh and do two jobs that quads don't: bending the knee and extending the hip, which makes them central to every deadlift, sprint, and hip hinge. They're also the muscle group most linked to injury risk when undertrained relative to the quads, since a big strength imbalance between the front and back of the thigh puts extra strain on the knee. A complete hamstring routine trains both of its functions separately: Romanian deadlifts, good mornings, and hip thrusts build hip-extension strength, while leg curls and glute-ham raises isolate the knee-flexion side that hip-dominant lifts barely touch. Work in the 8 to 12 rep range for isolation movements and let deadlift variations cover heavier, lower-rep strength work. Twice a week is enough direct volume for most lifters, since hamstrings are already worked hard by squats and lower-body compound lifts. The most common mistake is training hip hinges exclusively and skipping leg curls, which leaves the knee-flexion function of the hamstring noticeably behind the hip-extension side. A second is rounding the lower back on Romanian deadlifts to chase a deeper stretch, which shifts risk from the hamstring to the spine for no real benefit. A third is neglecting eccentric control, lowering the weight slowly on a deadlift or curl, which is where most of the muscle-building and injury-prevention benefit actually happens. Barbells and dumbbells suit hip-hinge work well, while machines are the more practical option for isolated leg curls.
