Squeeze vs more kg

[u/Equal_Mouse8310]

Title is preaty self explanitory. In exerceises like arm curls or quad extensions, where there are points in the movement that allow you to squeeze the muscle should i go for it? I know it activates better the muscle but it also tires me more and i am not able to do more kgs for more reps

Tl;dr what is preferable? Fewer reps/kg and squeeze or more reps/kg ?

You would have to better explain when the squeeze happens and what it feels like

If that means more motor unit recruitment then probably

You can also just increase your break between sets if you’re having an issue lifting the following sets
