Muscle Contraction - Are You Working Out Hard Enough?

Build muscle and strength in the next 90 days… http://athleanx.com/x/train-hard-and-grow If you are trying to build muscle size or strength, it’s important that you understand the nuances of muscle contraction. In order to get a weight to move from one place to another, you have to contract a muscle. That said, muscle contractions are graded. This means, that a muscle will not contract with it’s maximum force unless called for by the task at hand. Knowing that muscles recruit motor units based on the size principle, in order to get a maximum or near max muscle contraction we have to learn how to optimize motor unit recruitment. One of the fastest ways to do this is to strive to lift heavier and heavier weights. Heavier weights will definitely recruit a more significant amount of your fast twitch muscle fibers than a weight that is far too light to challenge you. That said, lifting heavy is not enough. In order to maximize the force of your contraction and therefore the number of motor units participating in a contraction you have to have effort! Effort is voluntarily controlled by your brain. How bad to you want it? How much do you want to really get out of your workout? If you simply go through the motions of moving a weight from point a to point b, you’ll elicit a muscle contraction but most likely not strong enough to cause an overload or adaptive change in strength or size in the long run. In this video, I show you two examples of this. If you perform a cab
