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.
Any deadlift you do will hit your hamstrings, and the Classic Deadlift is one of the best. Bending over and using your lower back strength to lift heavy weights will help to keep your lower back, glutes, and hamstrings strong. You can do it at home with a heavy box, large soup cans, or a set of dumbbells or kettlebells.
