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.
A deadlift is a strength-training exercise that primarily targets your hamstrings, lower back, quadriceps and glutes. Building these muscles helps improve your body's strength and stability. The deadlift is a compound exercise that strengthens the muscles you use each day to bend and lift. Exercising proper form when performing a deadlift is essential to minimize the risk of injury to your hamstrings or lower back.
