what muscles are in your back
When it's done right, the deadlift is an excellent back exercise. As you pick up and put down the weight, your upper-back musclesâincluding your rhomboids, traps, erector spinae, rear deltoids, and latsâmust fire on all cylinders to keep your torso straight and your lower back from rounding. It's when you fail to engage these muscles that injuries can occur.
