the real question is, what would be the best way to warm up before attempting your 1RM
I prefer Jim Wendler’s percentage technique of working up to a max. This is what I do if I’m trying to work up to a max bench of 300.
Adjust according to your own numbers and start at 50% of your max, making 10% jumps until you hit 100%. Or you can hit 95% before 100%, which I tend to like better.
I’m sure it is a little different for everyone but how long do you rest between attempts?
