You also might want to add in a bicep
workout on your leg days and a tricep workout on your chest days. Again
this should depend on how your muscles feel that day. If you do decide
to do your biceps for example on your leg day, I suggest chosing two
bicep exercises and performing two sets each.
On Arm day (Friday) simply choose three
tricep and three bicep exercises. You do not have to choose the arm
exercises that I listed.
