When working two muscle groups a day

[JAYWHITE]

When working two muscle groups a day. Ex Back & Bi's is it better to do a bicep then back bicep then back or all of the biceps then all the back. Also how long should it take to work two muscle groups 1hr to 1hr and a half good?

do all back then do your biceps......
that workout depending on how many exercies you do shouldnt take you much longer than 1hr including warming up IMO......

I prefer to work the large muscle group first, but it doesn't hurt to switch it up every so often.

I mix everything all up. I can do most of my back excercises without relying too much on my bi's or tri's, so I'll do one set for my back, then one set for my bi's, then a different movement for my back and then a set for my tri's (something like that).

Its nice to switch it up... even superset back/bi's and chest/tris.... good pumps..
