new 4 day split--insufficient?

[mole351]

here it is:

monday: chest/back
tuesday: legs/abs
wed: rest
thurs: bis/tris
friday: shoulders/abs
sat & sun: rest

2 questions. how does it look, and is it insufficient if i don't spend an hour in the gym each day? i can easily spend an hour for my mon. and tues., but thurs. and fri. are tough. i.e.-bis/tris i do 9 sets for each--that would take me about 40-45 minutes. stupid question, i know, but would like an opinion.

I think thats pretty good. I might add one more rest day in there if you could. There is nothing that say you have to spend atleast an hour in the gym. Me, sometimes I spend an hour but most of my workouts last around 45 minutes. Most of the time less is more.
