If your quads keep stealing the spotlight while the back of your legs lag behind, your hamstring training probably has a gap. The best hamstring exercises for strength do not come from tossing a couple curls onto leg day, they come from training both the hinge and the curl so your hamstrings get strong where it actually counts.
What makes a hamstring exercise “best” for strength and size?
A great hamstring exercise does at least one of three things really well: it lets you load the hamstrings heavily, it challenges them while stretched, or it trains one of their two main jobs, extending the hip and bending the knee. The best plan covers all three across the week.
That is why no single exercise wins every category. Romanian deadlifts are outstanding for heavy hinge strength. Nordics are brutal for eccentric knee flexor strength, meaning the lowering phase where your hamstrings are lengthening under tension. Machine curls make it easier to pile on quality volume for size. Put together, that mix works far better than chasing one magic move.
Research backs that up. A biomechanics study found the bilateral Romanian deadlift produced the highest peak hamstring forces, including about 1.6 times body weight in the biceps femoris long head and 1.9 times body weight in the semimembranosus. At the same time, Nordic hamstring training has been shown to drive about a 40% increase in eccentric knee flexor strength after 9 weeks. Different tools, different strengths.
1. Romanian Deadlift
If you want one anchor lift for stronger, bigger hamstrings, this is it. The Romanian deadlift loads the hamstrings hard in a stretched position, which is exactly what a lot of leg programs miss.
Start with the bar in your hands, knees softly bent, chest tall, and ribs stacked over your hips. Push your hips back like you are trying to close a car door with them. Keep the bar close to your thighs the whole way down. Your knees should bend a little, but not keep drifting forward. If they do, the move starts turning into a squat, and your hamstrings lose tension.
How low should you go? Lower until your hamstrings feel maxed out and your back position still looks the same. For some people that is just below the knees. For others it is mid-shin. Deeper is not better if your lower back rounds to get there.
A lot of lifters feel RDLs more in the low back than the hamstrings. Usually the fix is simple: slow down, keep the bar close, and think hips back instead of chest down. Picture your hamstrings stretching like a loaded rubber band. That is the feeling you want.
Why it works so well
RDLs shine because they train the hinge pattern under serious load while the hamstrings are lengthened. That matters for both strength and growth. In that same biomechanics paper, the RDL also produced some of the greatest hamstring stretch of the exercises tested, which is a big reason it has such a strong reputation for building the back of the legs.
Best variation options
The barbell RDL is the classic choice for maximum loading. Dumbbell RDLs are easier to learn and great for home workouts or limited equipment. A trap bar RDL can feel more stable and comfortable if the straight bar bothers your back or hips. For beginners, dumbbells are usually the easiest starting point because you can keep the load lighter and the setup simpler.
2. Nordic Hamstring Curl
Nordics are one of the hardest bodyweight exercises in the gym, and one of the best. You anchor your ankles, keep your body straight from knees to head, then lower yourself forward as slowly as possible. That lowering phase is the eccentric, where the hamstrings are fighting length as they open up.
This exercise hammers the knee-flexion side of hamstring strength, which heavy hinges do not fully cover. It is also one of the best choices for building resilience. Hamstring strains are a big issue in sprinting and field sports, accounting for roughly 10% of injuries in field-based sports.
How to scale it without wrecking your form
Most people cannot do a full clean Nordic right away, and that is fine. Use a band in front of you for assistance, lower only partway through the range, or do slow negatives and push yourself back to the start with your hands. Those versions still train the important part.
The trick is to keep your hips extended and your body straight. If your butt shoots back, you are escaping the position. A shorter range with better form beats a face-first collapse every time.
Why athletes should care
Nordics are especially useful if your sport involves sprinting, cutting, or hard acceleration. In an 8-week study on competitive soccer players, both Nordic hamstring exercise and single-leg deadlift training improved hamstring strength, and the Nordic group also improved extremity symmetry index, a measure of left-right balance. That matters if one side always feels a little sketchy when you open up your stride.
3. Single-Leg Romanian Deadlift
The single-leg RDL builds hamstring strength, balance, and side-to-side control in one shot. It also exposes weakness fast. If one hip twists open or one foot wobbles like crazy, you get instant feedback.
Reach your free leg straight back as you hinge forward. Keep your standing knee soft, your hips square, and your pelvis level. The goal is not to spin open and chase range. The goal is to make your hamstring on the standing leg do the work.
If balance is the limiting factor, hold onto a rack, bench, or wall with one hand. That is not cheating. It is smart. Support lets you focus on the hamstring instead of turning the exercise into a circus trick.
When to use this instead of bilateral RDLs
Single-leg RDLs make sense when asymmetries are obvious, when heavy bilateral loading is not practical, or when you want a strong training effect with less total load. They are also a nice fit on home workout days with one kettlebell or dumbbell.
4. Glute-Ham Raise
The glute-ham raise is one of the most complete hamstring builders in the gym because it combines knee flexion and hip extension. Your hamstrings do both jobs, and this exercise makes them earn it.
On a glute-ham developer, start with your knees positioned so you can move freely without jamming the pad. Keep your hips extended and lower under control. Then curl yourself back up without snapping through the lower back. Done right, this feels like your entire posterior chain is joining in, but your hamstrings still take center stage.
Form cues that make the difference
Keep your torso and thighs in line as long as you can. Think long body, tight glutes, and smooth tempo. If you arch hard through the lower back to finish the rep, tension shifts away from the hamstrings and the lift gets sloppy fast.
If your gym doesn’t have a GHD
No GHD, no problem. Nordic curls, stability ball leg curls, and slider leg curls all cover similar ground. You lose some loading potential, but you still train the same pattern.
5. Good Morning
Good mornings are underrated, mostly because a lot of people avoid them. The catch is that technique matters here more than with easier hinge lifts. When you do them well, they train the hamstrings hard at long length and build real posterior-chain strength.
Set the bar on your upper back, unlock your knees, brace your trunk, and hinge by sending your hips back. Your torso tips forward while your spine stays neutral. The range is usually shorter than people expect. You do not need your chest parallel to the floor to make this work.
Who should use it carefully
If you are still learning how to hinge, start with the RDL first. Good mornings fit better as a secondary exercise for experienced lifters who already control spinal position well and want more hinge volume.
6. Lying or Seated Leg Curl
Isolation work still matters, especially if size is one of your goals. Leg curls train direct knee flexion without your grip, balance, or low back getting in the way. That makes them perfect for adding clean hamstring volume after your bigger lifts.
Use a full range, pull with intent, and lower with control. That last part is where a lot of people waste the exercise. If you just slam the weight back down, your hamstrings miss a huge part of the stimulus.
Seated vs. lying leg curl
The seated curl often has a slight edge because your hips are more flexed, which places the hamstrings in a more lengthened position. The lying version is still excellent, and it is easier to find in most gyms. The better machine is the one you can use well and progress consistently.
How to make machine curls more effective
Pause the squeeze for a second at the top. Lower for two to three seconds. Let your knees straighten fully without bouncing off the stop. Small fixes like that can make a basic machine suddenly feel a lot less basic.
7. Kettlebell Swing
A good kettlebell swing is not just cardio with a weight. It is an explosive hip hinge that teaches your hamstrings to load and snap powerfully.
The movement starts with a hinge, not a squat. Hike the bell back, feel your hamstrings catch the load, then drive your hips through to send the bell up. Your arms are hooks. If your shoulders are doing the lifting, the pattern is off.
What the swing is best for
Swings are best for power, conditioning, and athletic carryover. They reinforce fast hip extension and crisp hinge timing. For pure hamstring size, though, they work better as a supporting exercise than a main builder.
8. Hip Thrust or Barbell Glute Bridge
This is more of a support lift than a pure hamstring move, but it still belongs here. Strong glutes make your hinge stronger, your sprint mechanics cleaner, and your hamstrings less likely to do every job alone.
In both lifts, drive through your heels, keep your ribs down, and finish with the hips extended rather than your low back arched. Your hamstrings help extend the hip, especially when your feet are set a little farther out.
Bridge vs. thrust
The glute bridge starts from the floor and has a shorter range of motion. It is easier to set up and great for home training. The hip thrust uses a bench, gives you more range, and is usually easier to load heavily. If your setup options are limited, the bridge gets the job done.
9. Slider Leg Curl
Slider leg curls deserve more attention because they are home-friendly, nasty in the best way, and surprisingly effective. Put your heels on sliders, furniture pads, or even towels on a hardwood floor, lift your hips, and slide your feet out slowly before curling them back in.
This creates a big eccentric challenge, especially on the way out. Research on hamstring loading found the unilateral eccentric slider produced hamstring forces similar to maximum-speed sprinting. Not bad for something you can do in your living room between the couch and the coffee table.
Beginner to advanced progressions
Start with two-leg curls. If that is too hard, keep your hips down or focus on just the lowering phase. Once those feel solid, progress to full hips-up reps, then eventually to single-leg versions. Difficulty rises fast here, like turning one extra notch on a dial and suddenly realizing your hamstrings are on fire.
10. Stability Ball Leg Curl
The stability ball curl blends hamstring strength with trunk control. Lie on your back, place your heels on the ball, lift your hips, and roll the ball toward you while keeping your hips up.
It looks simple until you rush it. Then the ball shoots around, your hips drop, and your lower back tries to take over. Slow reps solve most of that.
Why this works for beginners
This exercise teaches posterior-chain coordination without heavy loading. You learn to keep the hips extended, control the curl, and feel the hamstrings working together. That makes it a solid entry point before harder curl variations.
11. Back Extension with Hamstring Bias
A standard back extension can become much more hamstring-focused with a few tweaks. Keep a soft bend in the knees, push your hips back into the pad, and think about driving through your heels as you raise your torso.
That shifts more work away from pure spinal extension and into the hip hinge. Done well, this becomes a useful accessory for strength and hypertrophy, especially when your main heavy work is already done.
Common setup mistake
Going too upright and extending aggressively through the spine turns this into a lower-back exercise. If your hamstrings never show up, that is usually why.
12. Bulgarian Split Squat with Forward Torso Lean
This is the surprise pick on the list. A Bulgarian split squat is not a pure hamstring exercise, but with the right setup it can hit the back of the leg much harder than most people expect.
Take a longer stride than usual and lean your torso forward slightly as you lower. That creates a more hip-dominant pattern and brings the hamstrings and glutes into the movement more. You still get plenty of quad work, but the balance shifts.
How to shift more work to the back of the leg
Use a long stride, keep your front shin closer to vertical, and let your torso lean naturally forward instead of staying bolt upright. If your knee travels far forward and your chest stays tall, the exercise becomes much more quad-heavy.
13. Conventional Deadlift
The conventional deadlift is a great total-body strength lift, but it is not number one for direct hamstring growth. Your quads help a lot off the floor, and the lockout does not keep the hamstrings under the same long-length tension you get from an RDL.
Still, it absolutely has value. If your goal includes overall posterior-chain strength, pulling power, and heavy loading, the conventional deadlift earns its place.
Why it’s not number one for hamstrings
It loads the hamstrings, yes, but not as directly or consistently as the best hinge and curl options above. Think of it as a great full-strength builder with decent hamstring carryover, not your most targeted hamstring hypertrophy tool.
14. Walking Bridge Walkout
This bodyweight move looks harmless until you do it right. Start in a bridge position, then take tiny heel steps away from your hips while keeping your hips lifted. Every step lengthens the hamstrings and raises the difficulty fast, like sliding a ladder out one rung at a time.
You do not need many reps. A few controlled walkouts can light up the back of your legs more than a much flashier exercise.
Best use cases
Bridge walkouts fit warm-ups, finishers, rehab-style progressions, and home workouts beautifully. They are also useful on days when you want hamstring work without adding much spinal load.
How to choose the right hamstring exercises for your goal
The best list is still just a list until you sort it by purpose. If your goal is strength, lean harder on heavy hinges and high-tension eccentrics. If your goal is size, add enough direct curl volume. If you train at home, use sliders, bridges, walkouts, and dumbbell hinges instead of waiting for perfect equipment.
Best picks for strength
For pure strength, the strongest choices are RDLs, Nordic curls, good mornings, glute-ham raises, and conventional deadlifts. Those give you the highest tension and the most carryover to serious lower-body performance.
Best picks for size
For hypertrophy, start with RDLs and leg curls, then add glute-ham raises, slider curls, and Bulgarian split squats. Size usually responds best when you combine heavy loading with enough total weekly work.
Best picks for beginners or home training
Bridges, stability ball curls, slider curls, walkouts, and dumbbell RDLs are the easiest wins here. They are simple to set up, easy to progress, and much less intimidating than jumping straight into Nordics or barbell good mornings.
How to program hamstring exercises for strength and size
For strength, your hamstrings respond best to heavy loading, full range of motion, and repeating the work often enough to get good at it. The ACSM 2026 resistance training position stand found the best support for strength gains came from loads at or above 80% of 1RM, 2 to 3 sets, complete range of motion, and at least 2 sessions per week.
For size, more weekly volume matters more. That same review linked hypertrophy more strongly to 10 or more sets per week. In plain English: one hard set of RDLs and a prayer is not enough.
Sample setup for strength
Across two weekly sessions, a simple setup works well. On day one, lead with heavy RDLs for 3 sets of 4 to 6, then do Nordic negatives for 2 to 3 sets of 4 to 6 controlled reps. Finish with back extensions or a leg curl for 2 sets of 8 to 10.
On day two, use a second hinge or unilateral pattern, like single-leg RDLs or good mornings, for 3 sets of 5 to 8. Then add glute-ham raises or slider curls for 2 to 3 sets of 6 to 8. Keep the quality high and the reps clean.
Sample setup for hypertrophy
For size, spread 10 to 14 weekly sets across two or three sessions. One day could include RDLs for 3 sets of 6 to 8, seated leg curls for 3 sets of 10 to 15, and Bulgarian split squats for 2 to 3 sets of 8 to 10 per side.
A second day could use dumbbell RDLs or good mornings for 3 sets of 8 to 10, slider curls for 2 to 3 sets of 8 to 12, and back extensions for 2 sets of 12 to 15. More volume, more control, more direct work.
How many reps and sets to use
Heavy hinges like RDLs, good mornings, and conventional deadlifts usually fit best in the 3 to 8 rep range. Machine curls, split squats, back extensions, and ball curls often feel best from 8 to 15 reps. Nordics and sliders are special because the eccentric matters so much, so fewer reps with slower lowering usually beats higher-rep slop.
Form mistakes that keep your hamstrings from growing
The biggest mistake is turning every hinge into a squat. If your knees keep drifting forward and your hips stop traveling back, tension leaves the hamstrings.
Another common problem is cutting the range short before the hamstrings ever lengthen enough to work hard. Then there is the classic bounce, dropping fast into the bottom and using momentum to get out of it. That is just borrowed movement.
Loading too heavy too soon is another trap, especially on Nordics, sliders, and good mornings. Your ego heals slower than your muscles. And on unilateral work, balance can hide weakness. If you are wobbling so much that the hamstring never gets a clear job, use support and train the muscle instead of the drama.
When sore hamstrings are normal , and when to back off
A dull ache, tightness when you sit down, or that careful walk down the stairs the day after Nordics, all normal. High-eccentric exercises are famous for soreness, especially when you have not done them in a while.
Sharp pain is different. Sudden pulling, pinching near the sit bone, bruising, or pain that changes your stride is your sign to stop pushing through it. The fix is not to panic, just to back off, reduce range or load, and let the tissue calm down before building again.
Try this simple hamstring workout first
If you want a straightforward first session, do this at your next gym visit: Romanian deadlifts for 3 sets of 6 to 8, seated or lying leg curls for 3 sets of 10 to 12, and slider leg curls for 2 sets of 8 slow reps. That covers the heavy hinge, the direct curl, and the eccentric challenge without overcomplicating anything.
Stick with that for a few weeks and notice what changes. Your hinges should feel cleaner, your hamstrings should finally feel like they are doing real work, and the back of your legs should stop getting treated like an afterthought.
Frequently Asked Questions
How often should you train hamstrings for strength?
Two sessions per week is a strong starting point. That matches the best-supported frequency for strength gains in the ACSM position stand, and it gives you enough practice with both hinge and curl patterns.
Are Romanian deadlifts better than deadlifts for hamstrings?
For direct hamstring growth and tension, yes. RDLs usually keep the hamstrings loaded longer in a stretched position, while conventional deadlifts spread more work across the whole body.
Do you need both hinge and curl exercises?
Yes. Hinges train hip extension under load, while curls train knee flexion more directly. Your hamstrings do both jobs, so your training should too.
Are Nordic hamstring curls good for beginners?
They can be, but only with regressions. Band assistance, partial range reps, and slow negatives make them manageable and much safer than forcing full reps too soon.
Can you build hamstrings at home without machines?
Absolutely. Dumbbell RDLs, slider leg curls, stability ball curls, bridges, and walkouts can build a lot of strength and size when you progress them consistently.
Why do your hamstrings cramp during curls or bridges?
Usually because the hamstrings are weak in that position, or because your body is not used to producing tension there yet. Lower the difficulty, slow the reps, and keep practicing. Cramps often fade once your control improves.
