What is Muscle Inhibition?
Essentially, it’s a muscle that is receiving no or distorted neurological input. The easiest way to tell if you have muscle inhibition is when you move a muscle at the joint and it feels sluggish and lacks range of motion. Muscle weakness can start with muscle inhibition. You are still able to train and workout with inhibited muscles. However, that muscle is only going to get as strong as it can contract.
Remember, only the muscles that can contract fully are the muscles that are getting stronger. For example, if biceps short head is getting more signal than biceps long head the bicep short head will always overpower the long head and become stronger. The more that long head is left out the weaker it becomes over time.
How to Work Out Your Muscle Inhibition
Feel you have inhibited muscles? One way to increase your muscle signal is to do isometric exercises that are contractions of a specific muscle or group of muscles.
You can do isometric exercises against a stationary object or with gravity. To increase the signal to the gluteus medius, stand or lie down and push your leg into the wall with 10% effort and hold for about 6 seconds. Rest and repeat for at least 6 repetitions.
