Hey so today I am going to take a couple moments to talk to you about motionless exercise. Now the fitness trends are about as plentiful as fashion, they come and they go, you hear those words all the time. Motionless exercise is one of those new ones and that's what's floating around and I am going to clear up for you what it is. Nothing, nothing really complicated, motionless exercise is really referring to something called an isometric contraction which is really simply just when your muscle is not lengthened or shortened and the joint angle does not increase or decrease. For example my bicep muscle here in a curl, I would be curling that is a contraction you are accustomed to, this would be an isometric contraction not moving one way or the other. Normally you see this in pushing motions and I am going to show you today one that you probably never thought was an isometric contraction but it does qualify. This is a bridge and all you are going to do is come down here and some people align your fist with your shoulders and you are sort of in a pushup position and I am going to come up, raise your body up like that and you will notice nothing is moving, I am tense in my abdomen but nothing is changing one way or the other, the back is not flexing or extending, my abs are staying at the exact same joint angle. Elbows aren't changing, shoulders aren't changing. This would be considered isometric. Other examples of isometric motion include something as simple s pushing against the wall without actually changing your joint angle in your elbow. So do some more research on isometric contractions. You can incorporate that into your exercise routine and see how it can most benefit you and that's how to perform an isometric contraction.
