If someone can already do 15 or more chins, would you expect this type of work lead to just getting better at bodyweight chins (and endurance), or overall pulling strength and mass are expected as well?[/quote]
If there is to be an increase in muscle mass (which is not always desirable for individuals who need pulling strength-endurance like climbers) it will be dependent on doing a lot of overall volume (many many sets of the course of the day).
If you can do 15 chins for 2-3 sets several times per day (meaning that you can probably max out at 20-22) then strength gains will be minimal, but you will increase strength-endurance relative to your bodyweight, which is what climbers normally need.
You can still perform the same protocol (2-3 sets several times a day, 2-3 reps short of failure) with added weight if you can do 15-20 chins or more. In that case use a weight that would allow you to do a maximum of 10 quality chins and do several sets of 7-8 reps per day… add 5lbs or so every 2-3 weeks.
Or if you want a more precise protocol…
Using a weight you can get 10 quality chins with:
Week 1: many sets of 7 reps throughout the day
Week 2 many sets of 8 reps throughout the day
Week 3: many sets of 9 reps throughout the day
Week 4: add 5lbs and start the progression with 7 reps[/quote]
Christian,
For bi and lat muscles as foundation (Chin up) you use the “old method” to add a rep each week,as it must be done with straight series and rep range from 6 to 12 reps.
But if it was a muscle performance (overhead), it would be better to add a series every week rather that reps?
Because it is better to stay white low reps for performance muscles?
I just want to know if i understand your principe 
Pour bi et lat (fondation)tu utilise la veille methode qui consiste a ajouter 1 rep chaques semaines,puisque cela doit etre fait avec des series directe et dans la ranger de 6 a 12 reps.
Mais si cela etait pour un muscle de performance,serait il mieux de ajouter des series plutot que des reps?Mieux de garder les reps basses pour ces muscles?
Merci
