Take a look at your training program. How many horizontal pressing movements do you have? How many horizontal rowing movements you have? Compare the two numbers. Are they the same? Probably not. What about the number of posterior chain movements compared to the number of quad dominant movements? Are those numbers the same? Probably not. These are two examples of imbalances within a training program. An imbalanced program is a faulty program setting you up for injury or poor results. A well designed training program will emphasize balance between movements and muscles.
