Is using references for anatomy practice good?

So if I constantly 2 hours a day or 1. Copy a bunch of anatomy reference and draw it. Different poses and drawing multiple limbs. Will I'm a month I improve and be able to draw better WITHOUT a reference? Or does a reference slightly help. I want to know if that I spend 2 hours a day just drawing a bunch of limbs making them similar to an reference if it will help me overtime when I try to draw my own stuff.
