I am trying to understand the workings of Greasing the Groove (GTG) method (youtube video) With this method you should only do 50 % of the max reps you are capable of but do as many sets as possible every day and with minimum 5 of minutes break in between.
In hypertrophy training on the other hand you are supposed to go to failure and you may only have to do 1 set twice a week ("The 4-Hour Body"). Also the exercises should be performed slowly (5 seconds down and 5 seconds up).
So to me GTG sounds like the exact opposite of hypertrophy, which would make it pure strength. This would also mean that almost all progress is neurological adaption. Is this correct?
Does this mean that the rep count should be low (3-5)? I see some youtube videos of people trying to go from 50 to 100 push ups by doing 25 several times a day. This does not sound like pure strength or even hypertrophy but more like endurance training. So I am confused.
Also what should the tempo be in GTG? I understand that in strength you want controlled down (loading phase) and explosive up.
What is the use of GTG for ordinary people? I would think this would be how an olympic weightlifter train, but for ordinary people it seems impractical. I could imagine this being useful for getting past sticking points such as going from a very few to 10 pull ups for instance.
