how long between excercises when lifting?

[lowsweep]

I'm lifting for both strength and size. I usually wait about a minute and a half to two minutes in between sets, and usually do 3-4 sets of 6-10 reps per excercise (I change it almost every time I work out), while working the opposing muscle group in the same way between sets. I am wondering how long I should wait between excercises for the same muscle. For example, if I am doing biceps with bicep curls and hammer curls, how long should I wait after bicep curls before starting hammer curls? thanks,

For size, 1 to 1.5 mins is good. you don't want the muscle to fully recover, so you don't want a long rest period.
