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.
It doesn't involve chest that's for sure. Other than that, the primary target is lower back, core, traps, harmstrings and some other supplementary muscles. My favorite lift by far, just got 580 lbs two days ago. Even if it hit different muscles to some degree, don't expect your whole body to grow doing just deadlifts.
