Heres the thing.
This happens to me in several exercises, to be honest in almost all of them.
But to give you a clear example.
When im at the low row machine.
Ok, so I put half of the weight Id normally use for a set to warm up, but I really focus on the muscle mind connection, tempo of the reps, etc…
And obviously this way I really feel the lats/mid back working great.
Then when I hit the working sets, my grip or biceps, gets tired before the back muscles.
So its kind of obvious(I should go the way I feel my back more), but the weight I use for those sets its fairly light.
So what, should I pursuit heavy weight or muscle mind connection?
Just kidding!!
Im not asking for advice for myslef in this particular case but as a general question/ debate, should we bodybuilding practitioners aim for large amounts of weights even though we dont feel the right muscles?
Is it really needed to use heavy weights, in order to get BIGGER(not stronger necessarily)?
And I need to mention, I still feel my back during the heavy sets but just as I said before other parts get tired first.
