How do I warm-up for a one rep max?

[Sandy]

I want to try a 100 lb one rep for bench press next time I am the gym, but I am not sure what the ideal warm-up would be.

Thanks.

Something like

45x5
65x3
85x1

Go for it!

What is the benefit of going for the 1-rep max?

Outside of wanting to specifically know what your 1RM is, nothing.
