How to Work Out Your Hamstrings at AFAC Gym

When you think about building strong legs, your quads and glutes may get most of the attention. But there’s another major muscle group working behind the scenes, or, more accurately, behind your thighs. Your hamstrings play an important role in everyday movement, strength, balance, and athletic performance.

Whether you’re walking up a flight of stairs, sprinting across a field, picking something up from the floor, or powering through a challenging workout at Adventure Fitness Athletic Club in Thornton, Colorado, your hamstrings are hard at work.

That makes these muscles worth training intentionally. A well-rounded hamstring workout incorporates different types of movements rather than relying on one exercise. Hip-hinge exercises, leg curls, single-leg movements, and more dynamic exercises can all challenge your hamstrings in different ways.

Ready to give the back of your legs some well-deserved attention? Here’s what you should know about your hamstrings and some exercises you can incorporate into your next lower-body workout.

Hamstring Anatomy and Function

Your hamstrings aren’t one muscle. They’re a group of three muscles running along the back of each thigh: the biceps femoris, semitendinosus, and semimembranosus. Together, these muscles help control movement at both the hip and knee.

The biceps femoris is positioned toward the outside of the back of the thigh, while the semitendinosus and semimembranosus are located more toward the inside. Most of the hamstring muscles originate near the pelvis and extend to areas around the knee and lower leg.

Why does that matter at the gym? Because the hamstrings have more than one job.

Your hamstrings help you:

Bend your knee: Think about bringing your heel toward your backside during a leg curl.
Extend your hip: Your hamstrings help drive your leg backward and contribute to movements such as standing up, running, and hip-hinge exercises.
Control rotation: The hamstring muscles contribute to rotational movements involving the hip and lower leg.
Control movement: During walking and running, your hamstrings help control the leg as it moves and assist in stabilizing the knee.

Those responsibilities explain why a complete hamstring workout should include more than one type of exercise. A Romanian deadlift and a leg curl, for example, both train the hamstrings but challenge them through different movement patterns.

Why Focus on the Hamstrings?

It’s easy to prioritize the muscles you can see in the mirror. Chest, arms, abs, and quads often get plenty of gym time, while the muscles along the back of the body don’t always receive the same attention.

Your hamstrings, however, are far too important to ignore.

Strong hamstrings contribute to fundamental movements such as walking, running, jumping, squatting, and bending. They’re particularly important during movements involving hip extension and knee flexion, making them a major part of lower-body strength and athletic performance.

Training your hamstrings can also help create a more balanced lower body. Your quadriceps dominate the front of your thighs, while your hamstrings contribute strength and control from the back. A good leg-training program shouldn’t make you choose between them. It should challenge both.

The benefits aren’t limited to athletes, either. Strong legs support everyday activities, from climbing stairs and gardening to getting down on the floor and standing back up.

The good news is that effective strength training doesn’t need to be unnecessarily complicated. The American College of Sports Medicine’s updated 2026 resistance-training guidance emphasizes that consistency matters and that different forms of resistance training, including machines, free weights, bands, and bodyweight exercises, can produce meaningful results.

What Are Some Effective Hamstring Exercises?

AFAC gym gives you plenty of ways to train your lower body. Rather than searching for one “perfect” hamstring exercise, consider incorporating different movements that challenge both of the hamstrings’ primary functions: extending the hips and bending the knees.

Romanian Deadlifts

The Romanian deadlift, or RDL, is a classic hip-hinge movement that can place significant emphasis on the hamstrings.

Unlike a conventional deadlift that typically begins with the weight on the floor, an RDL starts from a standing position. With your knees slightly bent, push your hips backward while keeping the weight close to your legs. Lower the weight only as far as you can while maintaining good control and a stable spine, then drive your hips forward to return to standing.

You should feel tension developing through the back of your thighs as your hips move backward.

The goal isn’t to get the weight as close to the floor as possible. Your individual mobility will determine your range of motion. Prioritize a controlled hip hinge and proper form rather than depth.

Lying Leg Curls

Want to target knee flexion directly? Head for the lying leg curl machine.

Position yourself according to the machine’s setup instructions, bend your knees to bring the pad toward the back of your legs, pause under control, and slowly return to the starting position.

Resist the temptation to use momentum or lift your hips excessively to move more weight. A controlled repetition can keep the emphasis where you want it: on your hamstrings.

Nordic Hamstring Curls

Nordic hamstring curls are a challenging bodyweight exercise that emphasizes eccentric strength, meaning the hamstrings work hard while lengthening.

Starting from a kneeling position with your ankles securely anchored, gradually lower your upper body toward the floor while keeping your hips extended and torso controlled. Use your hands as needed to catch yourself and assist with returning to the starting position.

Nordic curls can be demanding, so beginners may need assistance or a reduced range of motion while developing strength.

This exercise has received considerable attention in sports training. Research has found evidence supporting eccentric hamstring strengthening, including programs incorporating Nordic hamstring exercises, as part of hamstring injury-prevention strategies for athletes, although adherence to the training program is an important factor.

Single-Leg Deadlifts

Single-leg deadlifts combine hamstring training with balance, coordination, and unilateral strength.

Stand on one leg with a slight bend in your knee. Hinge from your hip while extending the opposite leg behind you, keeping your hips controlled rather than allowing your body to rotate open. Once you’ve reached a comfortable range, engage your working leg and return to standing.

Training one side at a time can also help you become more aware of differences in balance, coordination, or strength between your legs.

If balance makes the exercise difficult, start with lighter resistance or use a stable object for support while learning the movement.

Seated Leg Curls

The seated leg curl offers another machine-based way to train knee flexion.

Once you’re positioned properly in the machine, bend your knees and pull the lower pad downward and backward. Pause briefly before returning the weight under control.

Although seated and lying leg curls involve a similar basic action, your hip position differs between the two exercises. Including different curl variations can provide some variety in how you train your hamstrings.

Kettlebell Swings

Kettlebell swings bring speed and power into the hip-hinge pattern.

The movement should be driven primarily by your hips rather than by lifting the kettlebell with your arms. Hinge backward, then extend your hips powerfully to propel the kettlebell forward.

Because kettlebell swings are faster and more dynamic than exercises such as RDLs, learning a solid hip hinge first is important. Start conservatively and focus on technique before increasing weight or speed.

Lunges

Lunges are often associated with the quads and glutes, but they can also be a useful part of a comprehensive lower-body workout involving the hamstrings.

From a standing position, step forward or backward into a lunge while maintaining control through your hips, knees, and torso. Push through your working leg to return to the starting position.

There are plenty of ways to vary this movement, too. Reverse lunges, walking lunges, stationary lunges, and weighted variations can all add a different challenge to leg day.

Warm Up Before Your Hamstring Workout

Don’t go straight from sitting in the car to your heaviest set of Romanian deadlifts.

A warm-up gives you an opportunity to increase your body temperature, move your hips and knees through comfortable ranges of motion, and rehearse the patterns you’re about to use during your workout. Warming up before activity is also among the recommendations for maintaining healthy hamstrings.

Before your working sets, consider spending several minutes on movements such as:

Leg swings: Perform approximately 10 to 15 controlled repetitions on each side.
Bodyweight hip hinges: Practice pushing your hips backward while maintaining good posture.
Glute bridges: Use a light set to activate the muscles along your posterior chain.
Light warm-up sets: Before heavier RDLs or leg curls, practice the exercise using less resistance.

The goal isn’t to exhaust your hamstrings before the workout begins. Think of your warm-up as preparation for the work ahead.

What Are Some Signs Your Hamstrings May Need More Attention?

You don’t need to wait until your hamstrings feel weak to start training them.

If your workout routine is dominated by quad-focused exercises with very little direct hamstring work, that’s already a good reason to consider creating a more balanced program.

You may also notice that hip-hinge exercises feel awkward, maintaining control during single-leg movements is difficult, or your posterior chain tires quickly compared with the front of your legs. These observations don’t necessarily mean there is something medically wrong with your hamstrings, but they can be useful feedback when evaluating your training routine.

Pain is different. Persistent or sudden pain shouldn’t be treated as a cue to simply work the muscle harder. If you’re experiencing ongoing pain, significant weakness, or symptoms related to a possible injury, stop the activity and seek guidance from an appropriate healthcare professional.

Common Hamstring Training Mistakes

Doing the right exercises is only half the equation. How you perform them matters, too.

One common mistake during Romanian deadlifts is turning a hip hinge into a movement driven largely by the lower back. Instead of simply lowering the weight toward the floor, think about sending your hips backward while maintaining control through your torso.

Another mistake is choosing more resistance than you can manage properly. If you have to swing the weight, rush through your repetitions, or dramatically alter your technique to complete the set, reducing the load may allow you to perform higher-quality repetitions.

Also watch out for:

Rushing the lowering portion of an exercise. Control matters in both directions.
Using an unnecessarily short range of motion. Work through the range you can comfortably control with proper technique.
Ignoring knee-flexion exercises. Deadlift variations are valuable, but curls train the hamstrings differently.
Skipping hip-hinge movements. Likewise, don’t rely exclusively on leg curls.
Training through pain. Muscle fatigue and effort during a workout aren’t the same as sharp or sudden pain.
Doing too much too soon. Increase resistance, volume, and exercise difficulty gradually as your ability improves.

For most gym-goers, consistency and progressive training are more useful than chasing complicated techniques. ACSM’s 2026 guidance similarly notes that advanced programming methods aren’t required for the average healthy adult to benefit from resistance training.

How Can Hamstrings Get Injured?

Hamstring strains occur when muscle fibers are stretched or torn. These injuries are especially common during activities that involve sprinting, jumping, lunging, or sudden acceleration and deceleration.

Hamstring strains vary in severity. A mild strain may involve a relatively small amount of tissue damage, while a partial tear involves greater disruption of the muscle fibers. A severe injury can involve a complete tear.

Symptoms can include sudden pain in the back of the thigh, swelling, bruising, weakness, difficulty walking or bearing weight, and, with more significant injuries, a popping sensation.

Risk can also be higher for people who have experienced a previous hamstring injury, have fatigued or poorly conditioned muscles, or participate in sports involving high-speed running and rapid changes in movement.

You can’t eliminate every possibility of injury, but sensible training habits matter. Warm up before exercise, allow your muscles appropriate recovery, build training demands gradually, and don’t try to power through hip, knee, or leg pain.

If you experience severe pain, substantial swelling or bruising, difficulty bearing weight, or persistent symptoms after a suspected hamstring injury, consult a healthcare professional rather than attempting to train through it.

What Are the Benefits of Hamstring Exercises?

Strong hamstrings aren’t just about improving your performance on leg day. Training these muscles supports many of the movements you perform in and outside the gym.

Make Everyday Movement Easier

Getting out of a chair, climbing stairs, bending down, gardening, playing with your children or grandchildren, and participating in recreational activities all depend on lower-body strength.

Building stronger hamstrings as part of a balanced resistance-training routine can help prepare your body for those everyday demands.

Support Athletic Performance

Running, sprinting, jumping, and changing direction all require coordinated lower-body movement. Because your hamstrings contribute to hip extension and knee flexion, they’re involved in many movements that require speed and power.

Build a More Balanced Lower Body

It’s easy for leg training to become quad-dominant, particularly when squats and similar movements make up much of your routine.

Adding hamstring-specific work helps you train the back of your thighs alongside the muscles on the front of your legs. A comprehensive lower-body program should account for both.

Add Variety to Your Training

Hamstrings can be challenged with barbells, dumbbells, kettlebells, machines, and bodyweight exercises. That variety gives you plenty of options for adapting your workouts to your experience level, goals, and preferences.

Build Strength for the Long Term

Resistance training can support muscular strength and physical function throughout adulthood. Current ACSM guidance emphasizes regular resistance exercise and notes that many different training methods can be effective when performed consistently.
