How each one starts
Barbell Good Morning — first steps
- Start by standing with your feet shoulder-width apart and the barbell resting on your upper back.
- Keeping your back straight and your core engaged, hinge forward at the hips, pushing your buttocks back as if you were trying to touch the wall behind you with your glutes.
Dumbbell Lying Leg Curl — first steps
- Lie flat on your back with your legs extended and a dumbbell resting on your lower abdomen.
- Bend your knees and bring the dumbbell towards your glutes, keeping your feet flat on the ground.

Which should you choose?
The Barbell Good Morning lets you load the heaviest weights and progress in small, steady jumps. The Dumbbell Lying Leg Curl works each side independently and demands more stabilizer control. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the hamstrings adapting.
