One of my clients asked me this question today:  “I put down below what I’ve been doing recently and was wondering if I’m doing sufficient work on the posterior chain.”

Here is his list of exercises:

  • Wheel Roll Out
  • Anti Rotation Planks
  • Bird Dog
  • Bulgarian Split Squat
  • Deadbug with Physio Ball
  • Glute Bridge
  • Reverse Lunge
  • Hip Flexor Stretch (Knee hug on back) – with core activation
  • Knee Hug, Calf Raise, Warrior Lunge Walk
  • Rotating Plank (lifting one arm up and then into a side plank)

The posterior chain, or PC for short, is composed of normally three muscle groups:

1. Paraspinals which line your spine
2. Gluteals
3. Hamstrings 

These muscles are considered the PC because they are on the back side of the body.  Some coaches include any muscle you can’t see as part of the PC (e.g. upper back and calves); however, normally, only these three muscle groups are considered part of the PC.  Therefore, any exercise that utilizes and strengthens these muscles would be a PC exercise.  
Makes sense right?

Typically, runners have overdeveloped quadriceps and hamstrings, but more importantly is the strength ratio between the hamstrings and the gluteus maximus.

Runner’s need to have a strong posterior chain because that is where a lot of the power comes from seen in the running stride.  Typically, runners have overdeveloped quadriceps and hamstrings, but more importantly is the strength ratio between the hamstrings and the gluteus maximus.  The big glute max should be the power house of hip extension, but most of the time, the hamstrings like to crash the party and take over.  This can be problematic for a runner.  This muscle imbalance can lead to long term issues with the hamstrings, hips and knees.  Runners need to improve the strength and recruitment of their posterior chain to:

  • improve power output (improve running performance and top end speed)
  • improve gluteus maximus strength relative to hamstrings (injury prevention)
  • improve tissue resiliency to overuse injuries

Well, lets go through the list of exercises above and see what their individual focus is.

Wheel Roll Out – Core stability (anti extension); target muscles anterior core; NOT PC specific.

Anti Rotation Planks – Core stability; target muscles entire core; paraspinals are involved but not PC specific.

Bird Dog – Core stability; target muscles abdominals, paraspinals and gluteals.

The paraspinals are activated to maintain a neutral spine.  This is one of Professor Stuart McGill’s favorite core stability exercises.  He’s the man who wants to kill crunches.  Anyway, the gluteals are also activated to maintain an extended hip to hold the leg straight out.  This exercise however is still not PC specific enough.  The main focus of this exercise is core stability.  Also, it can only be progressed and loaded so much that it will not develop strength in the PC as other exercises can.  These exercises will be discussed a little later…

Bulgarian Split Squat – also known as a rear foot elevated split squat or RFESS; target muscles quadriceps, hamstrings and gluteals

This exercise is one of my favorites for developing lower leg strength and pelvic stability.  Because this exercise is performed on one leg, the stance leg’s hip has to stabilize the entire body.  This muscle does not get strengthened with running alone and is associated with knee injuries and IT Band Syndrome.  (This muscle I’m referring to is the gluteus medius by the way).  Anyway, like I said, this exercise is great and can be progressed by adding more weight or holding the weight in different positions.  For example, a weight can be held in each hand like a suitcase or a barbell can be placed on the upper back.  To increase difficulty, a heavy kettlebell can be held in the front racked position or even over head.  However, after saying all that, this exercise is still not as PC specific as others.

Deadbug with Physio Ball – Core stability; target muscles entire core; NOT CP specific.

Glute Bridge – WINNER; CP specific; target muscles gluteals, hamstrings and paraspinals.

This exercise is considered PC specific because it utilizes the posterior chain to work together to perform the exercise.  Essentially, by lifting the hips, they are moving from a flexed position to an extended position.  The movement can be performed for reps or held for time.  It can also be loaded by placing a dumbell or barbell across your hips.  This exercise can actually be loaded very heavy depending on how much weight is added to the barbell.  However, in most gyms, you wont see any one perform this exercise loaded, unless they have been coached.  To improve strength, runners should lift heavy (sets of 5 or less) and this is one example where sets of 5 can be performed with a heavy bar held across the hips.  Normally, I include this exercise, unloaded with weight, but enhanced with a band in the muscle activation section of a runner’s warm-up.  The version in the picture not only activates the gluteals to extend the hip but also the hip abductors and the tibialis anterior (front shin) (both very important to a runner’s health!).

Reverse Lunge – target muscles are similar to the RFESS; NOT PC specific enough even though the hamstrings and gluteals are involved in the lift.

Hip Flexor Stretch – obviously a stretch to lengthen the hips flexors; NOT an exercise.

Knee Hug, Calf Raise, Warrior Lunge Walk – this is a dynamic warm up exercise I have my runners perform in their dynamic warm up (duh!).  The quadriceps, hamstrings and gluteals are involved in the lunge but this drill isn’t loaded; it’s only performed with body weight; therefore, it does not strengthen the PC as good as other exercises which are loaded can.

Rotating Planks – Core stability; target muscles entire core; NOT PC specific.

So, out of the exercises listed above, only one focused on improving the entire PC. Therefore, to answer his question, I would say he is NOT training his posterior chain as effectively as he could.

Stay tuned for important posterior chain exercises that are important for runners to perform.

Thanks for reading,

RUN STRONG.

I originally joined JKC because I was anxious about passing out and embarrassing myself since I hadn’t weight trained in a while and I’d hoped to find somewhere sympathetic. My husband @terry_hussey had been training at JKC and his success there made me miss the achievement you feel from a good workout. I went to meet Jon and immediately knew it was going to be a safe space for me. I was never judged for the fears I had and where I was starting from. Jon and Thomas made sure to check on me often, and found a way to challenge me but make me feel secure at the same time, and Terry and I were able to book sessions together, so working out became a shared win for us!

JKC is different from other gyms because of the personal growth you have outside JKC (the sessions inside JKC creates a great positive feedback loop!). You gain self confidence, learn how to show up for yourself, meet a community of newfound friends, and get the support of your trainers who are behind you 100%. I’ve left a scattered workout so proud of myself I’ve honestly shed a tear in the car on the drive home. JKC is the mental health relief valve I need to stay positive, and keep my anxiety and health related fears at bay.

I started strength training at JKC in the Spring of 2021. I am in my 60’s but happy to say I feel much younger since joining this gym. I joined JKC upon the advice of a doctor. I went through some difficult medical issues last year, that’s when one of my doctors recommended strength training at JKC. I have been physically active most of my adult life but mainly running and completed many road races as I am a distance runner. Strength training has definitely benefited me by increasing my stamina and energy. It sure has enhanced my recovery over the past year. I have the added benefit of becoming a stronger runner as well.

I’m 30 — started at JKC Aug 2016. I moved to NL to open lululemon and we chose Jon as one of our store’s ambassadors, did one workout and have raved about it ever since! The JKC team can adapt a workout no matter what the situation — injuries, new goals, you name it! The trust and expertise can’t be matched!

I had virtually no real experience using weights and felt intimidated going gyms. I avoided gym-goers using free weights, especially when hearing that loud crash, as they would drop weights to the floor. I thought this was to show everyone around them that they owned that area and that I shouldn’t go anywhere near! So I guess I just wanted to learn how to lift weights safely in a gym environment.

I spent over 18 years in the British Military, so I got to use some nice gyms. 99% of my time and experiences in those gyms was spent doing cardiovascular workouts, because I could just jump on a treadmill, plug in my head phones and do my own thing! JKC is different, because they have given me the confidence to use free weights and equipment that I had feared for years. Their demonstrations and knowledge is impeccable and I thank them for their continuous belief and support they show me at every session.

I’ve been weight training on and off for years but never really had a specific goal or target in mind so routinely stalled out, plateaued or stopped training all together. Before I joined JKC I was definitely in a fitness slump and needed something to motivate me and get me back on track. I did a bit of digging online, looking at various personal training options and gyms around town but JKC seemed like the best option by far. I’ve tried big box gyms and other personal trainers in the past but none of them have had the perfect combination of goal specific fitness programming, welcoming and supportive environment, and the knowledge and passion to back it all up that you’ll find at JKC. Jon and Thomas are great to work with, they know how to motivate you if you’re having an off day and are well versed in all the different ways to make your muscles burn! I also have noticed some major improvements in my deadlifts since I started with JKC and was really happy with the result.
