The 6 Best Dumbbell Hamstring Exercises

By RJ Sasseen, personal trainer at HiTone Fitness Brunswick, competitive bodybuilder and amateur kickboxer.

The best dumbbell hamstring exercises are hip hinges (the Romanian deadlift, stiff-leg deadlift, good morning, and single-leg deadlift) paired with a knee-flexion move (the dumbbell hamstring curl or hamstring march). Your hamstrings do two jobs, extending your hips and bending your knees, so a complete dumbbell routine loads both.

Key Takeaways

• Load hinges heavy and curls light. Deadlift variations respond to 8-12 hard reps, while dumbbell curls work best at 12-15 reps with a deliberate squeeze at the top.
• If you feel a hinge in your lower back instead of your hamstrings, the weight is too heavy or your back is rounding. Reduce the load and push your hips back further.
• The stiff-leg deadlift name misleads: your knees stay soft, not locked. Shifting your pressure toward the middle of your foot moves the stretch into the hamstrings.
• Good mornings punish ego lifting. The dumbbell sits far from your hips, so 5-10 pounds is a legitimate starting weight even for experienced lifters.
• Superset a hinge with a curl (Romanian deadlifts into bench hamstring curls, for example) to cover both hamstring functions in one pairing.
• Two hamstring sessions per week with at least 48 hours between them beats daily volume, since the hamstrings recover slower than most muscle groups.

How Dumbbells Train Your Hamstrings

The hamstrings are three muscles (the biceps femoris, semitendinosus, and semimembranosus) that run from your pelvis to below your knee and perform two movements: hip extension and knee flexion. EMG research published in the Journal of Strength and Conditioning Research recorded some of the highest hamstring activation in hip-hinge movements like the Romanian deadlift, which is why four of the six exercises below are hinges.
Dumbbells also let you train each leg on its own, which exposes and fixes strength imbalances a barbell hides. They place less load on your spine than a bar, and every movement here fits a home setup or a busy gym floor where the barbells are taken.

The 6 Best Dumbbell Hamstring Exercises

1. Dumbbell Romanian Deadlift (RDL)

The Romanian deadlift is the top dumbbell hamstring exercise because it loads the muscle through its full hip-extension range while it lengthens under weight, the stimulus most tied to hamstring growth.

1. Stand with your feet shoulder-width apart, a dumbbell in each hand resting in front of your thighs.
2. Keep a slight bend in your knees, push your hips back, and slide the dumbbells down your legs.
3. Stop when you feel a deep stretch in your hamstrings, around mid-shin for most people.
4. Drive your hips forward to stand, squeezing your glutes at the top.

Sets and reps: 3-4 sets of 8-12. Keep the dumbbells close to your legs the entire time; the further they drift forward, the more your lower back takes over.
This exercise is part of our 30-minute leg workout routine. Make sure to check it out.

2. Dumbbell Stiff-Leg Deadlift

The stiff-leg deadlift is an RDL with straighter knees, which shifts more of the stretch into the hamstrings and reduces glute involvement. The name oversells it: your knees stay soft rather than locked and locking them out only strains the joint.

1. Hold the dumbbells in front of your thighs with an overhand grip, feet hip-width apart.
2. With your knees nearly straight, hinge at the hips and lower the dumbbells in a straight path.
3. Lower until your hamstrings stop you, then stand by driving your hips forward.

Sets and reps: 3 sets of 10-12. If you struggle to feel this in your hamstrings, focus your pressure on the middle of your foot rather than your heels; where you load the foot changes where you feel the stretch.

3. Dumbbell Good Morning

The good morning trains the same hinge pattern as a deadlift, but holding the dumbbell behind your head moves the load far from your hips, so light weights create heavy tension. That leverage is the whole point, and it is why this movement humbles people who skip straight to a big dumbbell.

1. Hold one dumbbell behind your head or hug it across your chest, feet hip-width apart.
2. With a slight knee bend and a flat back, hinge forward until your torso approaches parallel to the floor.
3. Squeeze your hamstrings and glutes to return upright.

Sets and reps: 2-3 sets of 10-15, starting with 5-10 pounds. Progress the weight only when every rep moves with a flat back from start to finish.

4. Dumbbell Single-Leg Deadlift

The single-leg deadlift isolates one hamstring at a time, which corrects side-to-side strength gaps and builds the hip and ankle stability you lose from sitting all day. It needs less weight than any other hinge here to be brutally effective.

1. Hold a dumbbell in one hand and stand on the opposite leg with a soft knee.
2. Hinge forward, letting your free leg extend behind you as a counterbalance: as your chest lowers, the leg rises.
3. Aim for one straight line from your rear foot to your head, then drive through your standing heel to return up.

Sets and reps: 3 sets of 8-10 per leg. Move slower than feels natural; speed is what tips people over, not the weight.
If balance work like this keeps falling apart, a form check fixes it faster than more reps. Get in touch with our personal trainers in Brunswick.

5. Dumbbell Hamstring Curl

The dumbbell hamstring curl is the one knee-flexion movement on this list, and it matters because no hinge trains the hamstrings’ second job: bending the knee. Research in the Strength and Conditioning Journal supports the lying dumbbell curl as a practical substitute for the leg curl machine.

1. Lie face down on a bench with your knees hanging past the edge so your thighs stay supported.
2. Squeeze a dumbbell between your feet (a partner feeding it to you makes setup far easier) and grip the bench with your arms to brace.
3. Curl the weight up until your feet are above your knees, squeeze for a beat, and lower with control.
4. When the set ends, drop the dumbbell rather than lowering it past your knees.

Sets and reps: 3 sets of 12-15. Momentum is the main mistake here; if the dumbbell swings, it is doing the work instead of your hamstrings.

6. Dumbbell Hamstring March

The hamstring march is a bridge with a dumbbell on your hips where you march one foot at a time, forcing each hamstring to hold your hips up alone. It needs no bench, which makes it the easiest movement here to do at home.

1. Lie on your back, knees bent, feet flat, with a dumbbell resting across your hips.
2. Drive through your heels to lift your hips into a bridge and hold them level.
3. Lift one foot a few inches, place it back down, and alternate without letting your hips sag.

Sets and reps: 2-3 sets of 20 total steps. The hips dropping on one side is the signal to end the set, not to push through.

A Simple Hamstring Workout With Dumbbells

A complete dumbbell hamstring workout pairs one heavy hinge with one curl movement, done twice per week. Here is a session you can run in about 25 minutes:

1. Dumbbell Romanian deadlift, 4 sets of 8-10, resting 90 seconds between sets
2. Dumbbell single-leg deadlift, 3 sets of 8 per leg
3. Superset: dumbbell hamstring curl, 12-15 reps, straight into hamstring marches, 20 steps, for 3 rounds

On your second weekly session, swap the RDL for stiff-leg deadlifts or good mornings so both sessions hinge, but neither repeats. Add weight or reps only when your form holds through the final set.

FAQs

Do Dumbbell Squats and Lunges Work Your Hamstrings?

Not meaningfully. Squats, lunges, step-ups, and Bulgarian split squats are quad and glute movements where the hamstrings mostly hold position rather than shorten or lengthen under load, and EMG studies show their hamstring activation is low compared to hinges and curls. Keep them in your leg training, but count them toward your quads, not your hamstrings.

Can You Train Hamstrings at Home With Only Dumbbells?

Yes. Romanian deadlifts, stiff-leg deadlifts, good mornings, single-leg deadlifts, and hamstring marches need nothing but a dumbbell and floor space. The bench hamstring curl is the only movement here that requires equipment, and you can approximate it by lying face down on a mat and curling a lighter dumbbell held between your feet.

How Often Should You Train Hamstrings With Dumbbells?

Twice per week works for most people, with at least 48 hours between sessions. Six to ten hard sets per session is plenty; the hamstrings respond better to two quality sessions than to daily volume, because they take longer to recover than most muscle groups.
