which rm is better ?

[xolix]

3 or 1 rm on max effort bench... when do you use one of them and for which goals ? specially for raw benching ...

[rmccray]

well if its a max your looking for i think it should be one that would be the maximum amount of weight you could move! i also like heavy azz triples too know what im saying.

when you go for heavy trips, how many sets are usually recommended?

[waynedang]

I have always been a big fan of triples.

[Eric Downey]

triples are preferred. doubles are ok but all out heavy singles and your just asking for injuries

[BFGUITAR]

I personally like doubles, I have been having great progress with them.

It's also a probability thing...

The probability of you hitting a a weight you can only handle once over and over is much lower than the probability of hitting a weight you can only handle for 3 reps over and over (assuming you have done it).

A 3 rep max seems more assuring to me during training.
