Bad to finish week shreading upper body all at once???

Ok, here is a question. I just went to the gym and ended up hitting bi's, tri's, delt's, Trap's, and Lat's. Instead of the free weights I did the machines and did 8 sets each to failure on two different machines per muscle group.

Is this bad? I can barely type my arms are so tired. The reason I ask is that my normal routine seemed to be getting stagnet, I never feel it the next day. I figured I'd mix it up some. So is there a problem working out 3x a week and hitting the muscle groups, taking a day off and then hitting all the muscles in one big session if the muscles are not sore and seem recouped?

Thanks,

DMX

interesting question, would like to know this too :)
