In the minds of a great many people who train with weights, the deadlift is the exclusive domain of powerlifters. Few people include it in their programs, even if they’re primarily interested in gaining size and strength. In many gyms the deadlift is considered dangerous and not allowed. Then, of course, there’s the group that avoid it for a more basic reason — it’s taxing.
In fact, the deadlift is one of the very best core exercises in all of weight training, and it belongs in everyone’s routine, even trainees who aren’t interested in building great strength. What makes the deadlift so beneficial is that it involves so many large muscle groups — and since you can use a good deal of weight, it strengthens all he groups rather nicely.
