Yes, stiff leg deadlifts are a good exercise for strengthening the hamstrings and lower back.
The hamstrings attach to the ischial tuberosity of the pelvis and extend down to the tibia and fibula bones in the lower leg.
To properly perform a single leg reverse hyperextension exercise for targeting your lower back and hamstrings effectively, lie face down on a hyperextension bench with one leg hanging off the edge. Keep your core engaged and slowly lift your leg up towards the ceiling, squeezing your lower back and hamstrings at the top of the movement. Lower your leg back down with control and repeat for desired reps.
The action of bending the leg at the knee and pulling the foot backward is called knee flexion. Gym equipment allows users to pull up on a weighted lever behind the lower leg to strengthen the hamstrings.
Dumbbell stiff leg deadlifts involve keeping the legs straight while lowering the weights, targeting the hamstrings more. Romanian deadlifts involve a slight bend in the knees and focus on the lower back. Both exercises are effective for the hamstrings and lower back, but Romanian deadlifts may engage the lower back more.
The hamstrings are located on the back of the thigh.
This movement is called knee flexion. It is controlled by the hamstrings at the back of the thigh and the calf muscles. The knee joint flexes to allow the leg to bend and bring the lower leg towards the upper leg.
The dorsiflexors include the extensorum longus, the tibialis anterior, and the peroneus.

The hamstrings cross and act upon two joints - the hip and the knee. They extend the hip, flex the knee and rotate the lower leg inward when the knee is bent. The hamstrings also extends the hip as when beginning to walk; both short and long hamstring heads flex the knee and outwardly rotates the lower leg when the knee is bent. The hamstrings play a crucial role in many daily activities, such as, walking, running, jumping, and controlling some movement in the trunk.
To effectively perform SB leg curls for targeting your hamstrings and improving lower body strength, lie on your back with your feet on a stability ball. Lift your hips off the ground and roll the ball towards you by bending your knees. Hold for a moment, then slowly return to the starting position. Repeat for desired reps. Focus on engaging your hamstrings throughout the movement for maximum effectiveness.
