As a running coach, I’ve seen it time and time again: runners who log miles consistently, but neglect one of the most critical muscle groups for strong, efficient, and injury-resistant running: the posterior chain.
You’ve probably heard the term tossed around at the gym or in strength training articles, but it’s more than just fitness jargon. Your posterior chain includes some of the most powerful muscles in your body—your glutes, hamstrings, calves, and lower back—and they play a massive role in propelling you forward as you run.
Unfortunately, these muscles are often undertrained, especially in runners who focus primarily on quads and, well, running. The result? Muscle imbalances, poor running form, and a higher risk of overuse injuries.
In this guide, we’ll break down exactly what the posterior chain is, why it matters so much for runners, and how to build strength where it counts most. Plus, I’ll share some of the most effective posterior chain exercises and how to put them together into a smart, runner-specific strength workout.
What Are the Muscles In the Posterior Chain?
The posterior chain refers to the muscles that run along the backside of the body, beginning in at the back of the upper body and extending down the lower body to your feet.
Therefore, the posterior chain muscles include the following:
- Erector spinae (longissimus, iliocostalis, and spinalis muscles)
- Latissimus Dorsis
- Trapezius
- Glutes (gluteus maximus and gluteus minimus)
- Hamstrings (semimembranosus, semitendinosus, and biceps femoris)
- Calves (gastrocnemius and the soleus)
The reason that these muscle groups are referred to as the “posterior chain muscles“ is that they are on the backside of your body, which in anatomical terms is referred to as the posterior, and the muscles function as a sequential unit in a chain-like fashion.
What Causes A Weak Posterior Chain?
Spending too much time sitting and general inactivity are linked with a weak posterior chain.
Imbalances in these muscles are linked to poor posture, lower back pain, increased risk of injury during exercise, and worse athletic performance.1Posterior Chain: Exercises for Strengthening and Improving Flexibility. (2021, February 12). Healthline. https://www.healthline.com/health/posterior-chain#:~:text=While%20the%20posterior%20chain%20runs
How to Strengthen Your Posterior Chain Muscles
Your fitness level and primary training goals will largely dictate the ideal programming for your posterior chain workouts in terms of reps, sets, and loads.
- For strength gains, aim for 2–6 reps, 3–5 sets, and at least 85% of your one-repetition maximum (1RM) for the load. The fewer reps you perform, the closer to 100% of your 1RM you should strive for. This type of training is particularly beneficial for runners looking to build raw power and stability, especially important for uphill running and sprint finishes.
- For hypertrophy (muscle growth), perform 3 sets of each exercise using 70–85% of your 1RM for 8–12 repetitions. While runners don’t typically train for bulk, building lean muscle mass can improve durability and help prevent breakdown over high mileage weeks.
General guidance for most runners: A blend of both approaches often works best. Aim to include posterior chain strength training 1–2 times per week with moderate-to-heavy resistance for 6–10 reps per set. Focus on form, control, and compound movements that mimic running mechanics.
Strengthening these muscles will support better posture, stride efficiency, and injury prevention.
The Ultimate Posterior Chain Workout
#1: Barbell Romanian Deadlifts (RDL)
This exercise trains all the posterior chain muscles to work together as a functional unit.2Fischer, S. C., Calley, D. Q., & Hollman, J. H. (2021). Effect of an Exercise Program That Includes Deadlifts on Low Back Pain. Journal of Sport Rehabilitation, 30(4), 672–675. https://doi.org/10.1123/jsr.2020-0324
Here are the steps:
- Set the barbell so that it is at mid-shin height, with your feet hip-width apart. Keeping your back straight, hinge at your hips and grip the bar with your palms facing down.
- Unrack the bar as you brace your core. Keeping your chest up and shoulders down, press through your heels, using your gluteal and hamstring muscles to pull your body upright into a standing position.
- Keeping your core tight and back straight, hinge at the hips to lower the bar back down to lower shin/ankle level.
#2: Pendlay Rows
The Pendlay row is one of the best posterior chain exercises because it requires hinging from the hips and activating your entire PC in a very explosive and powerful manner.
Because the barbell rests on the floor in between reps, you not only maximize the stretch and range of motion, but you also have to lift the weight from a dead stop position, which is a great way to build power.
Additionally, even though the Pendlay row is less common than the bent-over barbell row, it actually tends to be better for your lower back because the barbell rests on the floor between reps.
Here are the steps:
- Set up as if you are going to do a barbell deadlift.
- Perform a hip hinge to reach down and grab the barbell with an overhand grip with your hands shoulder-width apart and your palms facing the floor.
- Exclusively press through your heels as you bend your elbows, squeeze your shoulder blades together, and bring your chest up as you pull the barbell up towards your sternum.
- Slowly return the barbell all the way to the floor by eccentrically loading your posterior chain muscles.
#3: Single-Leg Romanian Deadlifts
Single-leg Romanian deadlifts strengthen your posterior chain muscles while also challenging your balance, requiring hip, ankle, and core stability.
Here are the steps:
- Stand with your feet shoulder-width apart, knees slightly bent, chest up and proud, shoulders retracted, arms at your side, and a kettlebell in your right hand.
- Bring your left arm out to your side for balance and engage your core and glutes.
- Bend your left knee (the one on your standing/support leg) about 20 degrees to activate your hamstrings and glutes while you lift your right leg off the floor.
- Contract your glutes and hinge from your hips to bring your torso towards the floor, keeping your gaze on the floor to prevent hyperextending your neck. Keep your back straight. You do not want to be rounding your back or bending from your back; the hinging should all come from your hips. Your right leg should extend behind you as a counterbalance.
- Reach the kettlebell in your right hand down towards your left foot until you feel enough of a stretch in the hamstrings of your supporting leg.
- Engage your core and glutes to press through your heel to come back up, extending your hips until they are fully locked out. If you need to regain your balance, you can touch your right foot back down to the floor; otherwise, keep it lifted and move into your next rep.
#4: Kettlebell Swings
According to a research study conducted by ACE Fitness, kettlebell swings are one of the most effective hamstring exercises.3ACE CERTIFIED • February 2018. (n.d.). https://acewebcontent.azureedge.net/February2018/ACE_HamstringsStudy.pdf
Studies have also found that the kettlebell swing exercise is a highly effective movement pattern for improving functional body strength and decreasing the risk of low back pain.4Edinborough, L., P. Fisher, J., & Steele, J. (2016). A Comparison of the Effect of Kettlebell Swings and Isolated Lumbar Extension Training on Acute Torque Production of the Lumbar Extensors. Journal of Strength and Conditioning Research, 30(5), 1189–1195. https://doi.org/10.1519/jsc.0000000000001215
Here are the steps:
- Stand upright with your feet slightly wider than shoulder-width apart, gripping the horn of a moderately-heavy kettlebell with both hands. Your arms should be fully extended so the kettlebell is hanging down in front of your body.
- Keep your heels firmly planted but allow a gentle bend in your knees.
- Engage your core and glutes as you press through your heels and explode through your hips to drive the kettlebell upward until it’s roughly chest height and your arms are fully extended out in front of you.
- Control the kettlebell as it descends, loading your glutes and hamstrings. The kettlebell should swing back through the space between your legs somewhat.
- At the end of the arc of the swing, snap your hips forward again to drive the kettlebell back up to chest height.
#5: Stability Ball Hamstring Curls
This exercise primarily strengthens your hamstrings and glutes, but it also engages your abs and hip flexors. Extending the range of motion also helps strengthen your calves.
Here are the steps:
- Lie on your back with your legs straight and your heels up on a stability ball. Place your arms at your sides with your palms down on the mat.
- Engage your abs and glutes to lift your hips up so that your body is in a straight line from your heels to your head. Your shoulder blades should be down on your mat.
- Engage your hamstrings and glutes, and press your heels into the ball as you bend your knees to bring the ball towards your butt.
- You can roll even further so that you press your toes into the ball and allow your heels to come up. This activates your calves.
- Return to the starting position. Move slowly and with control.
#6: Rack Pulls
The rack pull is a variation of the deadlift that focuses on a smaller range of motion to target glute muscle lockout strength. Because of the reduced range of motion, you can lift heavier weights, which can help increase strength in your glutes.
It is also easier on your spine than a conventional deadlift because you aren’t moving as far, which makes it easier to maintain a proper neutral spine throughout the range of motion.
Here are the steps:
- Place the barbell at a level in the squat rack that is just above or below your knees.
- Face the barbell with a standard deadlift stance.
- Keeping your core tight and engaging your glutes, hinge down to grip the barbell, placing your hands shoulder-width apart and palms facing the floor.
- Retract your shoulder blades, squeezing your upper back while keeping your chest up and shoulders down.
- Press exclusively through your heels as you contract your glutes and pull the barbell all the way up until you have reached the lockout position.
- As slowly as possible, hinge at your hips and return the barbell to the starting level before performing the next rep. You should not re-rack the weight until you are done with your entire set.
#7: Hip Thrusts
Because your hips are elevated up on a weight bench, you can achieve a greater range of motion than with a glute bridge.
In fact, studies have found that the hip thrust can be more effective than squats at building strength in the glutes and more effective than deadlifts for activating the glutes.5Delgado, J., Drinkwater, E. J., Banyard, H. G., Haff, G. G., & Nosaka, K. (2019). Comparison Between Back Squat, Romanian Deadlift, and Barbell Hip Thrust for Leg and Hip Muscle Activities During Hip Extension. Journal of Strength and Conditioning Research, 33(10), 1. https://doi.org/10.1519/jsc.0000000000003290 6Andersen, V., Fimland, M. S., Mo, D.-A., Iversen, V. M., Vederhus, T., Rockland Hellebø, L. R., Nordaune, K. I., & Saeterbakken, A. H. (2017). Electromyographic Comparison Of Barbell Deadlift, Hex Bar Deadlift And Hip Thrust Exercises. Journal of Strength and Conditioning Research, 32(3), 1. https://doi.org/10.1519/jsc.0000000000001826
The glutes tend to be relatively weak in the posterior chain, requiring greater reliance on the lower back muscles and hamstrings even though the glutes are larger and more powerful muscles.
Therefore, performing glute isolation exercises can help improve your ability to properly activate your muscles while also increasing the strength and size of your glutes.
Here are the steps:
- Rest your shoulder blades and upper back on the long side of a weight bench.
- Bend your knees 90 degrees and place your feet flat on the floor hip-width apart.
- Rest a barbell along the crease of your hips. You can use a towel underneath for comfort.
- Squeeze your glutes and press through your heels to raise your hips up to a tabletop position so that your body is in a bridge. Your thighs should be parallel to the ground, and your shins should be vertical at the top of the rep.
- Pause at the top of the movement and squeeze your glutes into a full lockout.
- Slowly lower your hips back down, allowing your knees to travel naturally back inward towards your body.
#8: Glute-Ham Raises
The glute-ham raise is a great bodyweight exercise for the posterior chain, and it helps develop eccentric strength in your hamstrings.
As you get stronger, you can add weight plates or chains for posterior chain hypertrophy workouts.
Here are the steps:
- Secure your feet and then rest your quads in the middle of the glute-ham raise machine pad. Cross your arms over your chest.
- Bend your knees 90 degrees, and make sure to keep the rest of your body completely straight.
- Press your toes into the pad as you straighten your legs.
- Hinge at your hips to slowly lower your torso until your chest is parallel to the ground.
- Squeeze your hamstrings and glutes to lift your body back up to the starting position.
#9: Barbell Bent-Over Row
This classic exercise strengthens your lats, posterior deltoids, traps, and rhomboids. It’s also a great exercise for the upper posterior chain muscles.
Because you have to hold an isometric hip hinge position throughout the duration of the lift, the bent-over row improves the strength and endurance in your lower back extensors.
Here are the steps:
- Place the loaded barbell in front of your feet with your feet about shoulder-width apart.
- Hinge at your hips, keeping your core and glutes tight to maintain a flat and neutral spine.
- Reach down and grab the bar with your hands about shoulder-width apart and palms facing the floor.
- Pull the weight up to your stomach by bending your elbows and retracting your shoulders, maintaining the hinge at your hips throughout the exercise.
- Slowly lower the weight back down until your elbows are fully extended.
Bodyweight or Calisthenic exercises such as lunges, pull-ups, and press-ups can also massively improve posterior chain strength. Check out our guide:
