Valor 53lb Lifting Chains
Because the human body is stronger at some positions than at others, we are limited as to the amount of weight we can use in a certain movement. For instance, you may be able to do a quarter squat with 600 lbs, but you may be able to only full squat 400 pounds. We all know through practical experience that while doing a simple curl, at the start of the movement, is very hard, whereas at the finish it is somewhat easier because of changing leverage. This problem was first addressed around 1900 by Max Herz. His solution was the oblong cam, which he patented. Years later, the Nautilus line of exercise equipment tried to solve this age-old problem, -in my opinion unsuccessfully.
One lifter's strength will certainly be different from another lifter's at the same joint angle. Let's go back to the 1960s and power rack training. A power rack will, in one way, address this problem. For example, let's say a lifter can deadlift 600 pounds off the floor. Utilizing a power rack, with the weight 2 inches off the floor he can pull, let's say 625, and 4 inches off the floor, 650. By sitting the weight as high as 8 inches off the floor, he may be able to pull 750. In this manner, we have solved, at least partly, the problem of overloading, or providing adequate resistance as joint angles change.
However, it's difficult for some to display this new found strength to flow from from pin height to pin height. This can be explained by the fact that it is very seldom that one's body positions the same while pulling off the floor as it is while pulling off the rack. Isokinetics may be a partial solution, by maintaining a constant bar speed. But as with most machines, you must follow the path of the machine which is different from the path of a free weight. The path of a barbell is somewhat unpredictable at times. Another drawback is that prior to the start, as well as the finish, there is no load bearing on the lifter with this type of apparatus.
Is there answer to the problem of how to overload or adequately load the body to match the body's increase in leverage? Yes, there is.
Training with chains in this manner accomplishes three things. 1) We have maintained our original weight in order to use the correct percentage for explosive training. 2) We have overloaded the top portion of the lift, which normally does not receive sufficient work because of increased body leverage at this position. 3) A neurological response to build explosive strength is developed. This training will train you to drive to the top because you cannot slack off at the top phase as you used to.
Those who bench press 400 pounds or less should use 40 pounds of chain; those who bench over 500 should use 80 pounds of chain. Those in between should experiment with both amounts and aim for adequate bar speed. Remember, half the chain should rest on the floor when the bar is racked.
Lifters who have a sticking point at or slightly above the knees in the deadlift will also find great benefit from using chains. Attach the chains to the bar with a lightweight chain to adjust where the heavy chain will leave the floor and contribute to the weight on the bar.
