The university study I posted shows that if you are doing heavy compound movements you gain NO extra growth in the arms by doing isolation movements such as Curls, tri extensions.
Basically if all you did was curls and tri extensions at the gym, you would get some, but limited growth. As soon as you add in compound movements like Deads, Squats etc. there is absolutley no gain to be had by doing curls on top of these movements, you are literally wasting your time as it doesn't make a difference if you do them or not.
You do realize it's impossible to measure extra gain, in other words, it's impossible to assign which excercise actually produced the gains. We know that a heavy compound excercise will produce overall much greater mass, but how can one measure or even know if an isolatioon excercise did or did not contribute to the gain. If you are doing compound excercises, you are going to grow, but the growth flattens out, you gain less in the same period of time the further you go.
Determining that an isolation excercises contributed to no extra growth is totally bogus on all accounts. How can you know that, especially when gains become more linear vs exponential? The bicep won't whisper it in your ear, and you can't cut off someone's arm and open it count each cell and determine that the isolation excercise didn't contibute to gains. No one cannot possibly say definitively that an isolation excercise didn't contribute to gains. It's inmeasurable. impossible.
If you get gains by doing just isos and get gains by doing just compounds, a combination of compunds and isos will have to show better results than one or the other by itself. Those studies are bogus and they are leaving out the fact that the method of determination to distinguish gains/improvement as a direct result of one excercise or another when stimulating the same muscle is beyond the realm of human possibility. It can't be had and their conclusions of study still have a huge hole in the middle. That hole would be filled by a definitive answer to this question:
"How do you determine which excercise actually produced the stimulating effects that caused the muscle to respond in a positive manner as to grow and strengthen?"
You know what the answer is?
I do, and its:
"Oh, we can't definitvely say that one excrecise or another was a main, lesser or even soul contributor the stimulation of muscle growth. That's impossible."
The hole still remains, and so does the argument that doing curls is a 100% waste of time.
(Closing statement)
So, I will keep doing my curls, and benefiting from them while djeclipse doesn't do them and makes almost a good as progress as he would if he did. Buit that last little bit, however minimal it may be, is not a waste of time.
Let the jury decide. BTW, the jury is every bodybuilder that was ever somebody that made a name for themself, and they will find that doing curls and tricep extensions is not a waste of time.... Unanimously.
