Internal vs. External Cues



There’s a slight difference between learning a movement and actually performing it. Learning a movement can take a great deal of concentration, depending on its complexity. As you learn a movement or perform an activity, external and internal cues can help. These cues are generally given by a coach, trainer, or training partner, and they can either aid your performance or hinder it. 

But what are cues? And what are external and internal cues? 

When referring to “cues,” we mean the verbal cues that you receive when performing a lift. A good example of this is the mental image of a lifter, and his spotting bro, benching at the gym. One bro is performing his “epic” set of bench with 135, while techno/house music is blasting through his headphones, as his fellow gym bro yells “PUSH! PRESS! ALL YOU, BRO!” so the rest of the gym can hear. While extreme, this example describes a form of cueing. Even though the gym bro probably can’t hear his friend’s encouragement due to the high volume of pump-up music blasting into his ears, yelling “push and press” are a way of cueing.

There are two kinds of cueing, however, and while they may seem similar, they act in slightly different ways. 

External cues are results-driven. When cueing externally you are giving someone cues that take their focus “outside” of their body. An example of this is saying “stand up tall” when someone is squatting or “press to the ceiling” when they’re benching. By giving cues like this, you are taking the lifter’s mental attention and helping to focus it on the result of the lift. Giving and receiving external cues has also been shown to contribute to higher levels of force production when performing a lift.1

Internal cues concentrate specifically on the movement of the body. For example, this could mean cues such as “bend the knees,” “squeeze the bar,” and “hinge the hips.” Internal cues direct the lifter’s attention intrinsically and can be great when teaching movements. Through this method, a lifter or athlete can gain body awareness and begin to understand how a movement should feel, in order to self-correct as they gain proficiency.  

If you are attempting to cue for max performance, however, internal cues may be a hindrance. It has been shown that when receiving internal cues, there is a greater increase of muscle co-contraction.1 Co-contraction means that the prime movers are being counteracted by their muscular opposite. Think trying to flex the elbow but your tricep is also firing, so then the bicep has to work harder to complete the movement. That is co-contraction. In terms of efficiency, if your primary movers for a lift are already attempting to perform the movement, and then you add the resistance of your opposing muscle group co-contracting, you’re increasing the energy required to complete the lift. That is valuable energy that could be contributing to better efficiency when performing a lift or sporting activity such as jumping.

Although they’re similar, external and internal cues perform different tasks, depending on the outcome you would like to achieve. There is a time and a place for the both of them, but it is important to distinguish when to use the correct cues to optimize the result you want.

Strength and Plyometric Training for Runners



Running is not my first love in the world of fitness, but it's still an activity in which I partake. In my experience with the running population, runners love running… and that’s it. If you enjoy running, and it makes up the majority of your program, there are a couple of ways to bring your performance to the next level. Incorporating strength and/or plyometric training into your program can help optimize your running economy and performance. 

From a movement and injury prevention standpoint, weight training adds more movement variability to your life. Running is a very sagittal activity, where you're only moving forward and don’t shift into other planes of motion regularly. I’ve talked about moving in different planes and why that’s important in my post 3 Planes of HumanMovement, if you’re interested in reading more on that. Strength/plyometric training offers more benefits in addition to movement in different planes.

First, strength training can aid in increasing your relative strength. This makes your body weight a comparably lower percentage of your maximum strength, and makes every stride relatively less exerting. This adds up over long distances and periods of time. If your body is relatively easier for your muscles to move, the exertion of running becomes easier at a given pace. The adaptation to your muscles with strength training creates changes in your neuromuscular system. These changes train the muscles to contract in unison and synchronize their contractions to create a greater force output with each stride. These effects have been shown to have positive effects on rate of force development (RFD) and running economy (RE) for distance runners.1 When discussing strength training in this situation, however, they mean lifting 85+% of your 1RM for sets of 3-8 repetitions, with lower body exercise.

Additionally, plyometric training can improve your ability to increase RFD when running. Through both strength and plyometric training, you can train your ability to increase RFD with every stride. Due to the short duration of time that your foot is in contact with the ground when running, you want to be able to rapidly create force in a short duration of time. This is where the effects of plyometric training come into play. You can be really strong, but if you can’t generate force rapidly in a short period of time, you won’t get carryover into your running performance. Plyometric training enhances the ability to store and release elastic energy through passive elastic structures and use the stretch shortening cycle. Every time your foot contacts the ground when running, it needs to accept the load of your body, store the energy or dissipate it, and then release/generate force to propel you forward. The more effectively you can store and use elastic energy, the better RE you will have. 

This mechanism also takes the energy burden off of your active muscular structures, reducing the contribution from the anaerobic system.1 If a muscle is working at a high rate, it will develop lactic acid. I’ve talked about some lactic acid myths in the article 2 Myths, The Truth, and How to Deal With Muscle Soreness. Lactic acid creates an environment in which your muscle will begin to shut itself down. If you become better at using stored elastic energy and the stretch shortening cycle more efficiently, you increases your RE, increase RFD, and take some of the metabolic burden off of the active muscular tissues; this prevents the accumulation of lactic acid buildup at a given workload. Less lactic acid buildup when running equals better RE and performance.

I do have some recommendations regarding these training methods. Before you start performing plyometric exercises and strength training with 85+% of your 1RM, there are a couple things to take into consideration. Training progressions are the most important things to account for. 

1) For strength training, throwing around 85+% of a 1RM takes technique in itself. Technique changes, and can fall apart, quickly between 85-90, 91-95, 97, and 99% of your max. This is especially true for exercises like the squat and deadlift. Taking time to learn how to perform these will be more beneficial for your health in the long run. This is better than just going straight to 85+% of your max out the gates, if you have never lifted before or if your training experience in the gym is limited. Take the time to learn and develop these properly. It’s easy to get away with crappy technique at <80% of your 1RM, but the game changes when you venture into those higher percentages.

2) Plyometric training is shown to be beneficial to improve RE and RFD1, but it is also important to understand the forces acting on your body when performing them. Plyometric jumps can generate forces 3-5 times your body weight on impact.2 Before even performing plyometrics, it is important to have an adequate level of strength to accept the forces generated during this type of training. From there, after an adequate level of strength has been developed, plyometric training is safer and will be more effective due to better coordination and synchronization of muscle contractions. I generally like to see someone able to perform a squat close to 2x their body weight before beginning plyometric training.
