LET'S TALK ABOUT INERTIA . Inertia is resistance of a physical object to change in velocity. You may have heard the phrase "an object at rest tends to stay at rest" or Newton's first law of motion, "an object not subject to any net external force moves at a constant velocity". . Aka…nothing will change unless it is forced to change. . This is strength training. You have an external object moving (or not moving) downwards and we need to act upon it to move it the opposite direction. Better put, the weight isn't going to lift itself. . Now, let's apply this to the deadlift. You are the external force. The bar and plates are the object to be moved. . It will take a certain amount of force to break the inertia of the bar. This force is created by your muscular contraction. . Now, some people are "fast lifters" and others are "slow lifters". A lot of this comes down to how fast they can develop that requisite force, a term we call rate of force development. . When you aren't tight though the upper back, if you don't exert enough force to immediately break the ground, the bar will stop you in your tracks and likely throw you out of position, altering the load distribution across your body and making the lift much harder. ? . If however you pretension the bar and your whole body, you can then exert that force quickly or build it slowly and have no change in your leverages, making for a more efficient lift. . There is benefit here of irradiation as that will increase your strength as well. . So get tight, take the slack of out of the bar, and break the inertia. Because the weight isn't going to lift itself. ?? . Tag a friend who needs to improve their deadlift and share the wealth! . #Prehab101
