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.
Glute Muscles. The deadlift also targets your butt muscles, the gluteus maximus. This is the large muscle that runs diagonally down from the middle of your body to the outside of your thigh. It attaches to your pelvic bone and sacrum on one end and your femur, the thigh bone, on the other end.
