Body weight barbell rows represent the foundation of the upper body exercises along with unassisted pull-ups.

Most exerciser avoid these exercises for a number of reasons. The only reason that is acceptable would be a medical reason. In many cases these exercises are avoided because they are extremely challenging. They can also be complicated. It is much easier to use a machine that does most of the work for you.

If you are new to exercise and you are in poor physical shape it is fine to use the machines for a few months. The basic idea is to get the muscles ready for the real exercises.

Think of the next level in your training with the ultimate goal being able to use your existing body weight as the resistance you want to move with good form.

Develop a mindset of getting stronger if you are weak relative to your body weight. Once you can effectively move your body weight  or greater for multiple repititions,  using the largest muscles in your body,  you will dramatically impact how you look and perform.

Demonstrated below is the barbell rows with 225 pounds which is approximately 50 pounds more than my body weight.

My clients work at a level subject to their health history, strength training experience and their personal drive.

The basic idea is to learn proper technique and execution before pushing yourself to the limit. Keep in mind however, that it is by pushing yourself to the limit that you will achieve your greatest results.
