Quotes taken from last link:
"If you attach a cable set to some overhead anchor and suspend weights from its free end, it stretches farther and farther as you hang additional weights and builds up what is known in physics as elastic potential energy. Using the analogy of a fully cocked bow, the greater the amount of elastic potential energy stored, the greater force exerted on a released arrow and the farther and faster it will fly. Contrast this to, say, a barbell deadlift. If a bar is loaded to 500 lbs., applying 501 lbs. of pressure will lift the bar, but 499 lbs. will not budge it. So, to perform a press, a deadlift, or a squat, the exertion required to lift the weight can be relatively static and uniform throughout the whole movement. For elastic cables, the farther you stretch the cable ¾ like a bow, a slingshot, a bungee chord, or a trampoline ¾ the more resistance you encounter. A movement that begins with 60 lbs. of resistance may terminate at 100 lbs."
"One other sort of technical note about cables versus weights: when you pull or push cables through any motion, say, a Back Press, Front Pull, or a Overhead Pull Down, each side is under the full amount of resistance. So, if you have a cable set that provides 200 lbs. of terminal resistance in a Back Press (for your particular stretch of that cable set), each arm is under that load, not 100 lbs. for each arm. Remember, that in most cable exercises, your hands are opposing one another in terms of direction so each side feels the full brunt of the resistance from the stretch, not one half of it. This is different from, say, a barbell bench press where both arms are assisting each other to complete a movement by pushing in the same direction. So, the exerted pressure of a 200 lb. Cable Back Press on each locked-out arm is more accurately equivalent to one’s arms under a locked-out 400 lb. bench press, than a 200 lb. bench press. Think about it!"
Was just wondering if anyone had done any strandpulling or cable training or chest/backexpander exercises and what your experiences/opinions of them were....
