A body row is essentially a push up turned upside down.
It can be done by virtually ANYONE, as it achieves a strong rowing action without any stress to the lower back.
You can set the handles high, and position the feet so you are more upright, so the row is easy. Or you could set up so your arms hang straight down from the handles, and elevate your feet on a plyo box, and the row is much more difficult.
Some crazy folks can even keep their feet in the air, so that their entire body weight is in their hands....I consider that to be one of the hardest pulling exercises!
Whether you have access to a Smith Machine, a Squat Rack, some Bandit Loops, a TRX or a VERSUS, you can easily incorporate this into your routine.
Don't worry about "out growing" this exercise, as you can imagine are PLENTY of ways to make it more difficult ;)
Seeing as your strength training workouts HOPEFULLY consist of a push, a pull, a squat or a lunge and a core exercise.... the body row can add variety to your pull choices!
Another important reason to incorporate the row is the fact that you probably sit at a desk or in a car for SEVERAL hours a day, 5 days a week, so strengthening the awareness in your upper back
while improving your posture might just be what you need :)
There are also different ways to grip the bar or the handles while you are performing your body row. Whether its underhand, overhand, mixed grip, internal or external rotational as you pull in...I promise new muscles will be worked.
