haha, parallel dips are a tricep exercise. and chin-ups are a great mass builder for the biceps. if u keep yourself completely upright and not leaning forward in any way at all, as well as utilizing a closer grip, you are going to destroy your triceps better then most compound or isolation movements. MVP try throwing 10 sets of 3 of these dips into a routine and i can guarantee you that u will add mass to your arms.
I never said they won't
work your biceps. I just said biceps are not the agonists. You cannot curl your bodyweight, the lats are still the prime movers in a chin-up. I never once said that biceps aren't worked during a chin-up. My message clearly said they are not the agonists. Try doing skull crushers with your body weight, why can't you? Because the triceps aren't the prime movers, the chest is.
and as far as chin-ups go. they are my easily on of my favorite bicep exercises. yes of course the lats are involved in the movement but with a two second pause at the top and bottom, while really focusing on squeezing the biceps u can wear your biceps out much faster then your lats!!! and i mean really squeeze. it all depends on how u do the exercise. if you are not pausing and just swinging your self up you will not work your biceps as hard. but correctly done the chin-up is one of the best bicep mass builders there is.
Regardless of what you do, overhead pulling is the primary function of the
lats. The biceps will work harder during a chin-up than a pull-up, but is not the concentric mover. Can you curl your bodyweight? I doubt it. That's where the lats come in.
i dont mean this in a negative way MVP but i think u rely a little too much on what your personal training books are telling you rather then what you have experienced through training. chin-ups and dips are very good mass builders for the arms!!!!!!!!!
Once again, who said they wasn't a good mass builder for the arms? I said
they are not bicep dominant. The lats are the dominant muscle group. This is primary function of the lats. If two muscle groups primary function (in the case of a chin-up, elbow flexsion and overhead pulling, which is primary function of the lats and the biceps) the larger muscle group will always automatically take more stimulus. That's common sense, nothing a personal trainer book has to tell you. By the way, ACE is scientifically proven writings, but I don't let them tell me anything I didn't already know.
One of the reasons your lats exists is pulling in the vertical plane. It's a primary function, hence the chinning movement to stimulate the muscle tissue.
Biceps are not the main targeted muscle of a chin-up. The movement is dependent on the lats. Biceps are the synergists to the movement. Those small muscles in your arms alone could never handle your bodyweight. When was the last time you curled your bodyweight?
Common sense tells the rest of us that the bigger muscles are for the more demanding tasks with the smaller muscles providing assistance and stabilization, not PT books.
Chin-ups target the latissimus dorsi muscle, assisted by the brachialis, brachioradialis, biceps brachii , teres major, posterior deltoid, infraspinatus, teres minor, rhomboids, levator scapulae, middle and lower trapezius and pectoralis muscles. Chin-ups are thought to build width and thickness to one's back, as well as to promote growth of the biceps, brachialis, brachioradialis and pronator teres.

With your argument, are barbell rows biceps dominant? They will make your biceps grow. No, they are
synergists to the movement just like they are with chin-ups. Infront pushing is the primary function of the chest, when the chest primary function and the triceps primary function are in the same exercise, the chest will still automatically push more weight, this is factor of common sense and nothing more.
I am not disputing the biceps are not worked in the chin-up and triceps are not worked in the bench press. I am simply disputing that they are concentric movers and not synergists.
I took the liberty of proving my point with parallel dips too. Did you know they are called "chest dips"?
