I started a new program ,a basic 3 days program
monday : shoulders,chest,tris
wednesday: back and biceps
fridays : legs
There's this exercise that I really like,it's for the rear shoulders using the machine. It's an isolation exercise so it's not of major importance for beginners like me but anyways I want to do it.
Where does it go ? in the chest/shoulders day or in the biceps/back day ?
