Why are the rest periods between sets so critical?

[ucf465]

As stated above: why are the rest periods between sets so critical?

i rest 3-4 mins when i do a 5x5.

if im doing a 10RM per set how long should the rest periods be and why?

Thank you all

resting so you can lift more/heavier...not sure what/if theres a magic number of minutes...thought i'd bump it for you

i always wonder this as well and have read other theories...guess what works best for you is best

Just depends on what your goals are. If your just looking for pure strength take your time, 3 minute minimum.....If you're trying to build muscle I would stay in the 2min-3min range.
