An  ascending strength curve exists when you can display more force as you extend the joints; exercises such as deadlifts, squats, bench presses and military presses have ascending strength curves. Chains would be valuable for these exercises because the increasing resistance during the strongest joint angles would make the exercise feel  smooth through the entire movement.<BR>A descending strength curve exists when you can display more force as you flex a joint. An adductor (inner thigh) pull with cables or a machine would have a descending strength curve, as you can display more force when the legs are closest together. Some exercises have ascending-descending strength curves, which means that you can display more strength at the mid-range of the movement. Chins and standing biceps curls are such exercises. Using chains for exercises with descending or ascending-descending strength curves would not be very useful, as the chains would apply the most resistance in the parts of the exercise where you would be weakest.<BR>One important point to consider about strength curves concerns the effects of muscular fatigue. For a bench press, as the set progresses fatigue would make the athlete less strong at the finish of the exercise than at the start. Let s say an athlete can bench press 200 pounds and is trying to perform as many reps as possible with 160 pounds. For the first five reps the weight feels lighter at the finish, for the next five reps the weight feels even through the entire movement, and at about the 15th rep the athlete will only able to lift the barbell a few inches off the chest but cannot finish the lift. <BR>The practical application of the fatigue factor is that chains would not be appropriate for bodybuilding protocols that require high repetitions, such
