when you do a typical isotonic movement so same like a normal lift of a normal dumbbell something um you're only going to be challenged in the areas in the range of motion where you're the weakest so if you look at our study um on lifting with bands like heavy bands from a deadlift you're going to lift at the very very bottom and you're you're going to have very low load in fact like you could have as much as a 40% reduction and load at the bottom but when you come up and you start crossing the knee joint and you start gaining mechanical advantage it becomes extraordinarily easy but the bands start getting heavier and so the actual tenic that happens throughout the entire thing is is fairly equal if not well certainly greater at the top
