Why is now the time identify asymmetries before they cause a running injury? Does one side of your body consistently hurt more than the other? You may be suffering from asymmetries that have gone undetected.
Although asymmetries naturally develop over time due to varying strengths, limiters, injuries, and flexibility variances, it is important to address any underlying biomechanical problems to avoid endlessly chasing injuries. The site of pain may not be the root cause of the problem. It is important to dig a little deeper, and sometimes even look to the opposite limb to identify the issue.
Let’s take a look at Stan. When Stan was in high school, he sprained his ankle playing soccer. It was a mild sprain, so his athletic trainer recommended he take a few weeks off of working out or running. His trainer did not consider rehab, since this was a rather garden variety injury that just needed rest. Stan spent a few weeks watching movies and staying off his injured ankle as much as possible.
As Stan began running again a few weeks later, his gait mechanics had changed slightly to compensate for the injured ankle. His lack of ankle stability caused an inhibited gluteal muscle and decrease in core activation on the weaker side side. Slowly, one leg began moving differently to offload to the stronger muscle groups that were not coming off of an injury. He began flaring out one arm to stabilize his body against the unstable ankle. Over time, this new gait became his new normal. A year later, when he injured his left knee, his body went through a very similar process and built an entirely new gait adaptation layered on top of the old one.
But the time he made it into our clinic it took 3 months of diligent rehab to unravel these patterns and clean up the inefficient movement patterns. These new patterns were now leading him down the road to an additional hip injury, simply due to all of the off-loading behaviors his body had been developing from old injuries.
It is extremely common for runners to have non-functional (anatomical) asymmetries. Slight differences between left and right in bony anatomy are normal, though they can still cause problems. Maybe one tibia is internally rotated more than the left, or one leg is slightly longer than the other. It is important to avoid one leg working harder than the other to the point of break down, and thus causing injury, even due to anatomic variances.
While anatomic variance is normal, it is important to understand where your specific limiters are so that they can be accounted for in training. Usain Bolt, one of the fastest men alive, suffers from scoliosis and an asymmetrical running gait.
What can you do to better understand your body’s unique makeup and identify asymmetries before they cause a running injury?
Test for asymmetry by performing your regular routine, alongside the various exercises discussed in our previous blogs. While performing any movement, be aware of the differences between left and right. Start with balancing on one leg. Are you rock solid on your right leg yet you fall over on your left? How about a lunge? Does one hip feel tighter than the other? Now try going for a long run, does one leg seem to fatigue faster than the other? Continue to challenge your body in various ways and pay attention to your strengths and limiters so you can work through the weak areas in the gym before they become sidelining injuries on the run!

Ever wonder how to safely build endurance as a runner? If you have been following our blog series, you have been establishing adequate range of motion and mobility. Your balance and stability are now ninja-like…or at least ninja-in-training-like. Now, it’s time to focus on endurance so you can crush your next running goal and continue to improve your running performance. This post is an introduction to endurance and how to safely build endurance as a runner by incorporating non-running exercise into your weekly routine.
As mentioned in previous posts, running is a high-impact exercise. Trading a few running sessions out for low-impact exercises can increase your endurance fitness without adding additional load to your muscles and joints.
What exactly are we talking about when we say “endurance”?
There are two main types of endurance we will focus on to safely build endurance as a runner, cardiovascular and muscular. Cardiovascular endurance means how well our hearts, lungs, arteries, and veins take in, transport, and utilize oxygen. Muscular endurance is related to how many contractions our muscles can perform before they begin to fatigue.
How can you impact your cardiovascular endurance?
By varying intensity levels in each of these cardio exercises, you can start to increase the ability of your heart to have more cardiac output (heart rate x stroke volume). Improving the ability to get oxygenated blood through your body allows your muscles to continue to work at a higher rate. When you first start exercising, your ability to clear out carbon dioxide, shuttle hydrogen ions, and utilize oxygen is not great so your legs start to get “heavy” and fatigue quickly. As you gain cardiovascular fitness, you are better able to clear out that pesky carbon dioxide, shuttle hydrogen ions so they don’t build up in your muscles, and utilize oxygen so you can continue the activity for sustained periods over your previous capacity. If you are interested in learning more about how to create a running program based off of intensity levels, check out Jack Daniels’ “Running Formula”.
Remember, improving cardiovascular endurance means you need to perform exercises that stress the heart. Cardio exercises include things such as running, hiking, cycling, and swimming. Performing these exercises at varying and increasing intensity levels will improve your hearts cardiac output and your heart will become more efficient at pumping oxygenated blood throughout your body. The faster you transport oxygen to your muscles, the better they will feel and perform. Try adding a long bike ride or a swim, or even dancing (try Lindyhop!) into your weekly training plan. You will improve your endurance while challenging your body in a new way, which ultimately helps improve your run.
Now let’s focus on muscular endurance. Running is essentially a series of single leg hops that you perform over, and over, and over again. In order to get through any distance run, it is vital that your leg muscles have the endurance to continue to contract and relax with each step. In addition to propelling you forward, muscle contractions help the venous system return blood to your heart. The more efficient your muscles are at contracting against the veins to return blood to the heart, the better cardiac output you will have and thus, better endurance. Exercises to improve muscular endurance for running include body weight squats, lunges and pistol squats. Try these pistol squat progressions.
Remember, you will only stick with any exercise program long-term if it’s enjoyable for you! Choose activities that you WANT to spend time doing. Almost any sport can be turned into an endurance workout if done for sustained periods. Rock-climbing, Rollerblading, playing the drums…the list is endless. Be creative and both your run AND your brain will thank you for it.

Integrating strength training to enhance running performance and prevent running injuries is important for all levels of runners. At RunLab, it is not uncommon to hear from clients, “I can barely do a push-up.” “I never do strength training. I don’t want the bulk to slow me down.”
Runners need more strength as a population. This is a universal truth, and yet runners almost seem to take pride in the lack of strength training they do. Somehow the idea that strength training is detrimental to one’s running performance has taken a space in the collective running consciousness. Often neglected by distance runners, strength is very important for injury prevention and performance optimization and is often neglected. Having adequate strength will lower the probability of injury by preparing muscles to accept increased demand during training cycles.
In order to understand the importance of strength in the context of gait, let’s take a quick look at each phase of the running gait cycle:
If you look at the pictures, you can see that you are performing a series of single-leg squats and hops in rapid succession when you run. Due to the explosive nature of running, you are producing four to ten times your body weight in force PER STEP. It is vital to have sufficient strength to accept these loads if you hope to run injury-free. If you do not have ample strength in the primary working muscles, you will start to recruit smaller secondary muscles to perform the role of the primary muscles. Secondary muscles are not adequately equipped to do the job of a prime mover, either due to size or position in the body. Too much reliance on secondary muscles will result in a premature break down and aberrant movement patterns programmed into your body over time.
It is important to understand that strength comes in various forms. Functional strength is even more important than brute strength when it comes to a repetitive motion exercise like running. Being able to squat 2,000 pounds is an example of brute strength. However, this type of strength does not translate well to running. Functional strength is the ability to use your strength to perform your desired movement pattern under repetitive load. In order to be able to transfer strength to the desired movement pattern, one must be able to coordinate muscle firing patterns efficiently. Having functional strength will not only allow you to have more control over where the load is being produced while you are running, but also how efficiently the absorption load from the ground is transformed into propulsion energy. You gain functional running strength through performing exercises that look very similar to the running motion. Think of single leg squats, step-ups, or single leg plyometric exercises.

One important point in regards to strength training is the concept of “bulking up”. With regards to bulking up, it is important to understand that strength has two major components. One component involves the nervous system’s ability to recruit motor units. Your brain is a major piece of hardware. From your brain, you have nerves that act as wires that conduct electrical signals to motor units that control muscle contractions. The more you perform an exercise, the thicker the myelin sheath, or the insulation surrounding the nerves, becomes. This makes the signal from your brain to your muscles more efficient. The more efficient your brain is at activating motor units, the more force production you are going to be able to generate and thus the stronger you are going to be. Nervous system adaptations happen rather quickly and the strength gains you experience within the first eight weeks of a strength and conditioning program will be neurological.
The second major component of strength is the cross-sectional area of your muscle. You gain cross-sectional area, or hypertrophy when you cause micro-trauma to muscle tissue through exercise. The stressed muscle repairs itself by having the myofibrils increase in thickness and number. Cross-sectional muscular gains take at least eight weeks of training. This is part of the reason to get your running gait re-analyzed every eight to twelve weeks. This gives an adequate amount of time for neurological and muscular strength adaptations to take place.
A final word with regards to the idea that strength will “bulk you up and slow you down”. The main components contributing to muscle bulk are nutrition and the amount of testosterone in your body. You would have to work a muscle very hard, have the right amount of testosterone, and eat a specific diet to bulk up significantly. The amount of high intensity cardio most distance runners undergo keeps muscles lean, but we are often missing the strength to take full advantage of our high intensity workouts, which leads to injury and suboptimal performance.
Consider adding regular strength sessions into your weekly routine to help enhance running performance and prevent running injuries. Your body will thank you for it, and so will your mind when you hit that next PR because you didn’t break down half way through the race!
