Optimal Rest Time?

[Starcraftmazter]

When bench pressing, what is the optimal rest time between single lifts?

Also, what's an effective warmup, that won't wear out your muscles?

Cheers.

I would say rest time is up the the individual but for singles 2.5-3 minutes is what I use.

This is what I do for my warmup.
