As you have hopefully passed beyond the need to throw obscene amounts of weight around, it's important to realize that not only will you get better results from training by feel, but you will also tend to put less pressure on your joints. Don't get me wrong, it's still crucial to train to failure in the six to eight rep range using compound lifts. Those types of lifts are important, but they are not the focal point of every routine. Use intensity-building techniques such as rest pauses or dropsets, to recruit more muscle fibers.
When lifting it is essential to focus your mind completely on the muscle group you are attempting to work on. This makes sure that you are actually using the target muscle to lift the weight rather than accessory muscles or even momentum. This skill will develop with time, and as you progress in making that mind to muscle connection, your workouts will become much more productive and efficient.
