Training for total arm development
Seated dumbbell curls starting with a supinated grip (underhand) and rotating the forearms to a neutral grip (palms facing). A traditional curl movement, whether with a barbell or dumbbell, uses a supinated grip which works mainly the biceps. In a hammer grip or neutral grip the brachialis muscle of the upper arm and the brachioradialis muscle of the lower arm start to get involved along with the biceps. When you rotate the forearms all the way to a palms down grip (pronated) you are taking most of the bicep out of the movement and it becomes predominantly a brachialis and brachioradialis movement.
I like adding in the rotation like my client Justin is doing here when possible with bicep exercises as it enables you to work the biceps along with the brachialis and brachioradialis. The brachialis can often be neglected in arm training as many people only focus on the biceps and triceps. By doing this you do a big disservice to your arm development as the brachialis makes up a big part of the upper arm.
For total arm development be sure to include brachialis work in your program. #bicepsworkout #biceps #brachialis #brachioradialis #bicepcurl #bicepcurls #hammercurls #armtraining #dumbbellcurls #lasvegas #vegas #personaltrainer #strengthcoach #gymtrainer #fitnesscoach #fitnesstrainer #muscle #gym
