Everytime you get the chance on your back day skip the machines sometimes and the dumbbells and hit the pull up bar I promise you your back will look crazy the back is the biggest upper body muscle and is being used 24/7 so it can take a lot more of beating then your small muscles that don't get used as much like your chest
