How come when I lift ....?

Question

when i lift a lot of weight, i dont feel the stress on my muscles like when I lift lighter weight. I bench 120 max (not much), but when I bench a lot of weight i dont get off the bench with swollen muscles like when I lift something i can do 8-10 reps with. why is that?

Answer 1

try (heavist weight you can do) X 5x5

see if that will work

Answer 2

You are not tearing down and burning out the muscle like with the multiple reps. It is working though.

Answer 3

You lift more when you lift something light making your work out more effective.
