Less weight with many reps or More weight with less reps ?

Hi guys so lets discuss about this which one you think is better or which one you prefer to do when you are at gym ?

Let's start with you shall we?

ya i prefer easy with light weight and many reps like 30 reps with 3 set sometimes 4 set

Why so? What's yr rationale of doing high reps? Do you do that for all exercise?

Pump chaser. Curling pink db for 30 reps. Feels good on the muscles, less sore thus feel less crap, more motivated to go to the gym. Then open another thread asking why he is not grwoing. Most probably he wont reply after this.

Both have their places.
