While the lower back may be the easiest part of your back to acquire mass, it is also the easiest to injure. Think about all of the people with factory jobs spending all day picking up heavy boxes. These people will have very developed backs from doing this all day and they aren’t even weight lifters or bodybuilders.
The way people get injured isn’t necessarily the injured. I swear, you hear people all the time say all this shit about deadlifts being bad. This could not be further from the truth.
It is the way you perform the exercise. If you pick the bar off the ground with your back rounded like crazy, then yeah, of course you are going to get injured.
How to Get a Muscular Lower Back
Like mentioned above, this may be the easiest muscle to get built up. Obviously, the deadlift will be the best exercise to utilize to achieve this goal.
Deadlifts can also be dangerous since a lot of people just never figure out how to use correct form. Either that, or they will try to go too heavy to inflate their ego and sacrifice form in doing so.
Here’s a hint: if you have to round your back in order to deadlift 500 lbs, then you should probably lower the weight. Drop the ego and use the right form, please.
