Dumbbell Exercise Advantages
The advantages of dumbbells are both obvious and not so obvious: the obvious advantage for dumbbell use is they force each arm to carry its fair share of the payload. With a barbell, and particularly with machines, one arm can provide upwards of 55% of the push or pull force, allowing the weaker arm to stay weak. Dumbbells allow for far greater “pre-stretch” in bench presses, incline and decline presses. Where the barbell’s descent halts when the bar contacts the chest, dumbbells can be lowered further down creating an extended range-of-motion and stressing muscles to a degree unobtainable with barbells or machines. Dumbbell pressing stimulates muscle stabilizers maximally. More muscle stabilizer activation means more muscle growth.
