This should ruffle some feathers.
I think you can work a muscle group every day, and get results.
Think about this. A mechanic that uses his arm muscles tightening bolts all day, every day. He doesn't take one or two days off. Not if he wants to eat regular that is. How about putting up hay, the old fashioned way. Square bales heaved up onto a wagon then unloaded and stacked in a barn. You did this until the job was done. No days off. You got sore, but you did it any way. It made you strong, and after a summer of doing this kind of work, you looked it too.
If you want to work a set of muscles every day do it smart. Vary the routine, use heavy weights, and low reps, use light weights and high reps, use medium weights and moderate reps. Try for some functional work for the muscle set also.
I did this for my shoulders, and it worked great. Here is a quick overview of what I did:
Overhead Pressing
Monday: 5 x 5 heavy
Tuesday: 25 reps of 25% 1RM
Wednesday: 25 reps of 25% 1 RM
Thursday: 8 x 5 75% 1 RM
Friday: 20 reps of 20% 1 RM
Functional stuff on the weekends: Tire flipping, and bag work (sand and feed).
