Named Muscles. The specific primary muscles used in a deadlift are the erector spinae, gluteus maximus, quadriceps, hamstrings and adductors. The secondary or stabilizing muscles are the trapezius, rhomboids, flexors, extensors, serratus anterior, rectus abdominus, transverse abdominus, gluteus medius/minimus, soleus and the gastrocnemius.
The deadlift is a full-body exercise that works almost all muscle groups. It must be done carefully and with good technique, however, because an incorrect deadlift can strain muscles and joints in the back. sumo deadlift works the hip and groin muscles more than the conventional style. Any deadlift can be done with either a barbell or dumbbells. You start a barbell deadlift with your feet under the bar and roll it up your shins and thighs.
