GTG
GTG is about Technique and Neural development.
With novice lifter, increases in strength initially occur from the development of the nervous system. It also a key factor for advance lifter, as well.
It is best developed with lower repetition and higher loads.

Greasing The Grove: How To Make It Work For You
The phrase greasing the groove has been used in many articles. The basic premise in greasing the groove is to do the same exercise frequently, with every set performed without going to muscular fatigue. Let’s take a look at what it really means, the origin of the phrase, and some example...

"...It is about building up the neurological pathway of lifting heavy weight."
"...It is about building up the neurological pathway of lifting heavy weight."
"Greasing the groove methods provide a great way to build the neurological skill to move heavy objects. It is not a
hypertrophy type of program, but rather a way to build the muscle firing patterns for a max effort."
With that in mind, let look how to develop Technique and Neurological Skill
Technique Training
1) Performing an Exercise with a Load of 80% or more of a 1 Repetition Max
Loads of around 70% can be performed at time. However, they are not as effective as the use of heavy training load; load of 80% plus.
2) :Low Repetition Sets; 1-3 Repetition Per Set
3) Performing GTG Technique Training at the beginning of a training session, when you are fresh.
4) Taking long Rest Periods between GTG Technique Sets.
5) Stopping the GTG Technique Training Exercise once fatigue set in. Continuing to perform an exercise in a fatigued state produces poor technique. Also, the muscle firing sequence changes.
"If you chase two rabbits at the same time both are going to get away."
In other word, you need to focus on GTG Technique Training, "One exercise at at time."
